"Push me pull me" in industry!

Variant 4 of the Harting PushPull industrial connector family is ideally suited for providing reliable termination for today’s camera systems in applications such as industrial quality control or security surveillance.

The new connector is equally suited to industrial environments involving dirt and dust or outdoor applications subjected to heat and cold. Based on an intelligent building-block construction, their PushPull family offers a multitude of bulkhead-mounted housings, wall bushings, and connectors for a range of system configurations.

An important element of this system is the RJ45 connector for 1 Gbit/s and 10 Gbit/s Ethernet transmission in Cat 6 Class EA systems. This is available as an overmoulded system cable or as a field-installable connector with insulation displacement technology. Options for USB 2.0 (types A and B) and USB 3.0 (type A) are also available, as are optical solutions based on an LC duplex configuration.

In addition to the compact design, high data rates and rugged IP 65/67 construction, an essential characteristic of the PushPull series from HARTING is its suitability for simple and swift commissioning in the field, thereby guaranteeing short setup and installation time

14 October 2013 – Notification of abstract acceptance/denial
12 December 2013 – Draft papers and presentations due
7 February 2014 – Final papers and presentations du

The 2014 FPID symposium will bring together experts, vendors and end users in a two-day symposium to cover the critical challenges and issues in automation and serialization and how they are affecting food and pharmaceutical supply chains. Recent legislation and incidents of contamination and tampering have raised the importance of automation to reduce errors and implement enhanced serialization controls to improve tracking and tracing throughout distribution channels.

Serialization—the assigning and marking each product or product component with unique identifiers—in both the food and pharmaceutical industries is regarded as essential to protect consumers and to reduce risk exposure for food and pharmaceutical manufacturers, says Dennis Brandl, President of BR&L Consulting, Inc., who, along with Alex Habib, co-chairs the 2014 FPID Symposium.

“Upcoming product serialization requirements in the pharmaceutical industry, notably in California, are driving major projects and changes in the life science industries,” reports Brandl, whose company specializes in helping companies leverage manufacturing IT to improve their production and logistics processes. “In pharmaceuticals, it’s essential that counterfeit or tampered drugs are not introduced into the supply chain and end up with customers. That can obviously lead to some very dangerous situations.
“At the same time, a greater emphasis on tracking and tracing food products in order to prevent the sale and distribution of contaminated food is also prompting serialization in the food industry. Food serialization helps pinpoint the distribution and location of specific food products and lots, which is particularly valuable during recalls of contaminated foods. And because you can target in on specific lots of food, you don’t have to disrupt the flow of other, unaffected food supplies.”

Serialization, he points out, requires a highly coordinated, multi-faceted approach that integrates automation, supply chain management and information security.

“Effective serialization involves changes on the shop floor, in corporate business systems and with multiple supply chain partners outside of the company. For instance, printers and verification systems must be added to existing production and packaging lines. Information security is essential to safeguard the integrity of the data. And serialization information must be maintained in corporate ERP systems, and must be available on a 24/7 basis to production and supply chain partners.

Heat rate reduction kit!

Magnetrol International, has introduced the Heat Rate Reduction Kit, aimed at helping power companies manage controllable losses through effective, accurate feedwater heater level control. The Heat Rate Reduction Kit is available for download and addresses the mission-critical need to increase the efficiency of power plants in today’s challenging economic and regulatory environment. The Heat Rate Reduction Kit, an industry first, provides solutions that will help reduce fuel expenditures, which can account for 70% to 80% of production costs, by minimising heat rate. According to Magnetrol, the potential savings represent an estimated €500,000 annually for a 500 megawatt power plant.*

Included in the Magnetrol Heat Rate Reduction Kit are several useful guides to reducing heat rate, why it is important and how the process will help reduce costs:
• Heat Rate and Feedwater Heater Level Control white paper
• Managing Heat Rate and Controllable Losses video
• Next-Generation Level Instrumentation for Heat Rate Awareness and Control special applications bulletin
• Reduce Your Heat Rate and Drive Down Fuel Costs brochure

“We created the Heat Rate Reduction Kit because we recognize the challenges power companies face today in an increasingly competitive environment and with the advent of climate change protocols and the Clean Air Act,” said Magnetrol's Product Manager Jim Homoly. “The kit explains how minimizing heat rate can help plants use energy more efficiently and save significant fuel expenditures.”

The causes of heat rate inefficiency can be due to aging level instrumentation or instrument-induced errors, which negatively impact heat rate and fuel costs, according to Homoly.

“Effectively controlling feedwater heater levels drives overall plant performance and fuel cost savings,” said Homoly.

* A 1% improvement in heat rate is worth €500,000 in annual fuel cost savings based on: Fuel cost of €1.25/million kJ, capacity factor of 85% and boiler efficiency of 88%.

Torque sensor has upgraded communication

Kistler Instruments has launched a new version of its versatile KiTorq torque measuring system with additional data communication options.

The Kistler KiTorq torque sensor system is now available with Profibus, Profinet CANopen, Ethercat and EthernetIP interfaces in addition to the analog/frequency, USB and RS-232 interfaces. The new stator is fully compatible with all KiTorq type 4550A rotors.

The new communication options allow the KiTorq system to be integrated directly into the user’s test environment through the fieldbus interfaces. This saves time during installation and eliminates the cost of additional equipment to convert measured data making the new stator exceptionally cost effective for test stand design, installation and operation in applications for electric motor, internal combustion engine, transmissions, pump and compressor testing.

The new stator can be used with any KiTorq rotor of the same speed rating and will automatically recognise the rotor measuring range. With rotors available with seven measuring ranges from 100 to 5,000 Nm, hardware investment is minimised as one stator may be used with rotors of differing ranges for different applications. Installation is simplified by the contactless, digital telemetry that eliminates the need for an antenna ring whilst maintaining the excellent signal bandwidth of 10 kHz and accuracy of better than 0.05% of range. A speed measurement of 60 pulses per revolution is integrated in the standard system.

ZigBee enables new markets for device developers

Expanding ZigBee networks in the home will open up multi-billion dollar markets for Sentroller and Device Developers

GreenPeak Technologies tells us that the growing success of ZigBee sentroller devices (sensors, controllers and actuators) enables Smart Home device developers and integrators to expand their markets into new areas and multiplying their sales.

As virtually all cable operators and broadband service suppliers are starting to offer Smart Home services to their subscribers and have chosen ZigBee as the wireless communication standard, there will be an almost insatiable demand for affordable and easy to install Smart Home devices that connect to the set-top box. Device developers are just starting to recognize this great opportunity to offer all types of different Smart Home devices at very affordable costs. GreenPeak’s ZigBee chips enable device developers to build and market ZigBee based smart devices starting at less than $5 each.

Multi-Service Operators need these smart home devices to bundle into their roll out of connected home systems. These new services include security, home monitoring, energy management and control, elderly care, health care support, location monitoring, and even mundane things like automated window and door controls, light switches, etc., enabling profitable business models for both the device developers and the service providers alike.

“ZigBee allows device developers to address a very profitable Smart Home market, expected to grow to several billion units in 2015.” says Cees LinksFounder & CEO of GreenPeak Technologies. “In many ways, ZigBee’s worldwide reach of the market parallels the market acceptance of WiFi. Just like Apple’s adoption of WiFi was the tipping point for the spread of WiFi networking to every internet connected home, the operator and service providers’ adoption of ZigBee is the tipping point for ZigBee to establish ZigBee networking for sentrollers and small devices in every internet connected home as well.”

“Operators looking to expand revenue by offering home automation services are currently driving the majority of growth in the connected home market,” said Greg Potter of Multimedia Research Group, “Low chipset costs, good security, and low power usage have made ZigBee the protocol of choice for most cable providers today and will remain so for the foreseeable future. In fact, revenues for services derived from ZigBee backbones within the home are set to grow immensely over the next years and are driven primarily by cable providers and operators looking for new revenue streams by offering fifth play services.”

“Although WiFi would be technically capable to connect these devices, the battery life of ZigBee is superior compared to WiFi,” adds Cees. “In the future Smart Home we expect to see maybe 10 to 20 WiFi devices along with 100 or more ZigBee devices, all working simultaneously in the home, without any interference. WiFi will be handling the big data applications like entertainment, while ZigBee will connect the sentroller Smart Home network.”

Level detection sensors

Non-intrusive level measurement now also for conductive products

Adequate level measurement of conductive products inside a tank, like humid pet food, has been very difficult with highly sensitive materials, harsh environments (pressurized, abrasive, hot, corrosive) or complicated tanks. The resulting reliability issues have a negative effect on costs and downtime. To solve these problems, Fluidwell Instruments, a division of Fluidwell, launches an extension of its Triflex level detection sensors family: The LNI 250, a “Field Time Control” (FTC) based level detection sensor, which uniquely measures with great reliability from the outside of a non-metallic tank.

Measuring through small or complicated, non-metallic tanks for contamination sensitive or aggressive products,
Insensitive to changing process conditions stimulating higher output,
Easy access for faster maintenance without process interruption,
Saving cost on additives, installation and maintenance,
Insensitive to product accumulation on the walls.
Unit on dryer!

Discriminatingly unique
The distinguishing element of the Triflex LNI 250 is its ability to reliably measure conductive material in a non-metallic tank without having to be present inside that tank and therefore without product contact. The tanks even need not be transparent. Its discriminating benefits include no risks of contamination of the product, easy access for maintenance (without process interruption!), suitable for small/complicated tanks, easy plug-and-play installation, suitable for aggressive materials or environments and insensitive to changing process conditions inside a tank. The yield is remarkable: Lower costs, higher output in better quality and increase in reliable measurements.

Key applications
The Triflex LNI 250 is suitable in a wide range of applications, but especially for industries with conductive bulk products (solids and liquids) where product contact needs to be avoided (e.g. out of health reasons or with acids). Also where placement of a sensor inside a tank is not possible due to the construction of the tank (too small/complicated) or where the environment inside the tank is highly abrasive or subject to change, the Triflex offers the solution. As well as for any company that wants to profit from less hassle and cost involved with installation (one-button set-up) and maintenance (easy access)!

Field Time Control (FTC) Technology
The patented Triflex LNI 250 incorporates Field Time Control Technology (FTC). This technology generates an electric field between a transmitting electrode and multiple receiving electrodes. The cycle time of the FTC level sensor changes as soon as the solid particles are detected by this electric field. Advanced multiple receiver circuitry has been designed for reliably detecting various bulk products, (even with extremely low dielectric constants). The results are higher signals with less variation for increased reliability. This allows for minimizing cost, increasing revenues and providing clearer visibility of the process.

Single efficient solution
Louis Ras, General Manager of Fluidwell Instruments commented: “With the help of FTC technology we developed a unique product that makes a difference. The Triflex LNI 250 has been validated by several large manufacturers, including VOBRA, a producer of pet food in The Netherlands: Their set-up of a counterflow dryer for dog food, without access points on the inside, did not offer the option of measuring technologies like TDR/radar solutions. The Triflex LNI 250 has proven to be their only solution for a continuous and efficient process, stimulating output, margins and product quality. The additional cost benefits with installation and maintenance increased their satisfaction even further.”

Accurate & reliable ultrasonic level measurement for corrosive, harsh environments!

Rosemount® 3100 series now available with rugged and lightweight plastic housing with Ingress Protection rating up to IP66/67

Emerson Process Management has expanded the accurate and reliable measurement capabilities of the Rosemount® 3100 Series of ultrasonic non-contacting level transmitters to harsh environments with the option of a plastic (glass-filled nylon) housing. Available on the Rosemount 3101, 3102 and 3105 process level transmitters, the new housing is rugged, lightweight and corrosion resistant.

The plastic housing reduces the weight of the transmitter by 0.5kg compared with the standard aluminium version, making it suitable for installation on extended mounting brackets, or on thin gauge metal tank roofs or plastic tanks. Rated up to IP66/67, it is ideally suited to applications such as water storage installations and waste water and effluent treatment plants.

Rosemount 3100 Series ultrasonic level transmitters provide a cost-effective solution for a wide range of liquid measurement and control applications, providing accurate and reliable level measurement up to 11 metres (36 feet). The local operator interface makes installation and configuration quick and easy. The non-contacting technology with no moving parts enables a long operating life with minimal maintenance requirements.

The series comprises the Rosemount 3101 which measures level, and outputs it as a 4-20 mA signal, and the 3102 and 3105 which can calculate distance-to-surface, contents (volume), or open channel flow, and output the result as a 4-20 mA signal and a digital HART® signal. An integral temperature sensor continuously measures the air temperature around the transmitters. It then computes the speed of sound in air, automatically compensating the calculated distance for temperature effects. In addition, the Rosemount 3102 and 3105 have an optional remote temperature sensor.

The Rosemount 3100 Series is part of a broad range of Rosemount level measurement devices available from Emerson. These include guided wave radar, non-contacting radar, DP and hydrostatic level, ultrasonic, vibrating fork, float switch and specialised conductivity solutions for virtually any level application

Innovative new technology for improved safety, productivity and energy efficiency

With the introduction of the new MELSERVO MR-J4 series - and corresponding positioning modules, motion modules and high-end motion control systems - Mitsubishi Electric is now offering a servo amplifier which will enable machine manufacturers and end customers to improve both safety within the production process and productivity, while guaranteeing ease of operation and commissioning at the same time. The MR-J4, successor to the tried and tested MELSERVO J3 series amplifiers, scores highly in all categories by ensuring better performance and providing expanded functionality. Their target market for these units includes manufacturers of packing machines, indexing tables and handling systems.

MELSERVO MR-J4 product range with
rotating, linear and direct-drive motors.
Mitsubishi Electric has integrated a wide range of new user-friendly functions in its new series of amplifiers in order to minimise the time-consuming and complex operations involved in harmonising mechanical and electronic systems. The system makes adjustments itself quickly and easily by means of “online auto tuning” and automatic “vibration filters”. The customer can utilise these functions during start-up and during ongoing operation, enabling commissioning and parameterisation times to be reduced.

The amplifiers also have a “life diagnosis function” that monitors the actual condition of the components installed, such as capacitors and relays, throughout the life of the product. It also notifies the user and operator regarding any degradation in their operation, making both downtime and machine outage time a thing of the past.

The designers have also looked in to the future as far as safety and safety related functions are concerned. They have come up with a modular architecture which provides a redundant two-channel STO input (Safe Torque Off) as a standard on all MR-J4 amplifiers. This can be augmented by an additional option module to provide SS1 (Safe Stop) input in line with EN61800-5-2. The system configuration then also supports SIL2 (EN62061) and PLd (EN13849-1). For more advanced systems, and the highest levels of safety such as support for SS2, SOS, SLS, SBC and SSM, this can be achieved when Mitsubishi's MR-J4-B amplifiers and motion controllers are used in combination. This flexibility means that users can reduce costs by being able to "tune" their system configuration to meet only the needed safety requirements for the target application.

Another plus in terms of functionality and flexibility compared with its predecessor is the fact that a wide range of motors can be connected to the MELSERVO MR-J4 amplifier. Both rotating and linear or even direct-drive motors can be used with the servo amplifier, thus optimising the stocking processes for users.

The amplifiers are fitted with 22-bit absolute encoders as standard, providing a resolution which corresponds to more than 4 million pulses per revolution. The result: excellent rotational accuracy and optimum positioning accuracy.

Besides the MR-J4-A (analogue/digital/pulse train) and MR-J3-B (SSCNET III/H motion network), the MELSERVO J4 series from Mitsubishi Electric also includes two additional versions for two- and three-axis operation which are being offered for the first time. The two- and three-axis amplifiers (MR-J4W2B and MR-J4W3B) are correspondingly more compact and efficient than three individual amplifiers, not only saving the machine manufacturer money in terms of energy costs and reducing CO2 emissions but also saving on the space required in the switching cabinet.

Motors from the HG-KR/MR series are available for the lower output range from 50 to 750 watts. The maximum torque ranges from 0.48 to 7.2 Nm, with a maximum speed of 6000 rpm. The HG-SR series covers the medium output range from 0.5 to 7 kilowatts with a maximum torque of 100 Nm. All the motors have IP65 or IP67 protection (dust- and water-proof), making them suitable for use in the harshest industrial environments.
At the initial product launch, the 200-Volt version of the MELSERVO MR-J4 was first made available with servo motors ranging from 100 W to 7 kW. The 400-Volt versions from the MR-J4 series with servo motors up to a maximum of 110 kW has since been launched.

The PD6080 and PD6081 include dual analog inputs and an RS-485 serial communications module, allowing integration of existing 4-20 mA transmitters and Modbus devices on the same display. The PD6088 and PD6089 include on-board RS-485 serial communications and no analog inputs. The PD6081 and PD6089 have a unique feet and inches display, ideal for level applications.

The ProtEX-MAX PD8-6080 Super Snooper scanners are housed in explosion-proof enclosures for use in hazardous areas. SafeTouch®, through-glass buttons provide accessibility to the front buttons without removing the enclosure cover. The entire product carries FM, CSA, ATEX, and IECEX approvals for use in hazardous area applications.

"Most Modbus scanners are dated technology in the form of low-level software packages or DIN rail devices with no display," said Jeffrey Peters, President of Precision Digital Corp. "The Super Snooper scanners integrate sophisticated packet sniffing capabilities with industry standard packaging -- 1/8 DIN housing that meets NEMA 4X specifications or explosion-proof enclosures for hazardous areas. With the ability to poll up to 16 process variables, a single Super Snooper can replace an entire control panel’s worth of instruments."

The Super Snooper scanners can be easily integrated into an existing Modbus network. Remote displays can be added without making changes to other Modbus devices. In Master mode, the Super Snoopers are Modbus masters, polling slave devices for the process variables. In Snooper mode, the devices display any process variable being polled on the bus. All the process variables are clearly labeled with a custom tag and unit.

Each scanner is provided with RS-485 Modbus RTU serial communications standard. Options include up to four (4) relays, a 4-20 mA analog output, and dual 24 VDC power supplies.  Expansion modules for the 1/8 DIN models add an additional four (4) relays, two (2) 4-20 mA outputs, and eight (8) digital I/O.

LVDS digital I/O module for control & data capture applications

The Model 71610 digital I/O module with LVDS (low-voltage differential signaling) I/O connected to a Virtex-6 FPGA has been introduced by Pentek. This Cobalt® module provides 32 LVDS differential input or output pairs plus LVDS clock, data valid and flow control signals via an easy access front panel 80-pin connector routed to the Virtex-6 FPGA.

LVDS is a general purpose digital interface operating at very high speeds over inexpensive twisted-pair or flat ribbon copper cables. It is popular for many common control or data capture applications such as high-speed video, graphics, video camera data transfers and general purpose computer buses. The standard built-in data capture and data generation facilities of the Model 71610 make it an ideal turnkey solution for developing and deploying custom FPGA processing algorithms.

Data can be pulled from devices such as sensors, data converters, custom digital systems or spectrum analyzers and then processed, decoded or formatted in the Virtex-6 FPGA before delivery to the host system processor. Likewise, signals from the host can be processed and formatted by the FPGA before delivery to the LVDS output.

“The LVDS interface gives developers a low-level interface that is highly configurable to handle many types of unique interface requirements,” said Rodger Hosking, vice president of Pentek. “This module is ideal for custom I/O, which can be tailored to match a wide range of different LVDS peripheral devices.”

The Model 71610 is a VITA 42 XMC (switched mezzanine card) module that can plug into carriers such as VPX, CompactPCI, AMC (Advanced Mezzanine Card) and PCI Express. The Model 71610 supports x4 PCIe on the primary P15 XMC connector. The secondary P16 XMC connector supports dual 4X or single 8X user-installed gigabit serial interfaces, such as Aurora, PCIe or Serial RapidIO. The Model 71610 has an optional PMC P14 connector with 20 pairs of LVDS connections to the FPGA for custom I/O to the carrier.

Multiple Virtex-6 FPGA options are available so developers can select the best match for their processing and environmental requirements. The Virtex-6 is ideal for encoding/decoding, modulation/demodulation, encryption/decryption and channelization of signals between transmission and reception. 2GB of DDR3 SDRAM provides ample memory buffer space for transient capture, digital delays, DMA packet formation and signal processing algorithms.

Supporting Features and Products
Pentek GateFlow FPGA Design Kits allow users to develop and install their own custom IP for data processing. The kits include full VHDL source code for factory installed intellectual property (IP) functions, so developers can easily add new functions by incorporating additional FPGA IP modules.

Pentek's ReadyFlow board support packages, with high-level C-callable library functions and device drivers, are available for Windows and Linux operating systems.

Strain or temperature measurement

Measurement of strain or temperature in harsh environments often requires specialist equipment, preparations or processes, with the most common environmental challenges coming from:

• Multiple sensing points

Traditional electric technologies can sometimes only be used once sophisticated and expensive barriers, shielding methods or other protection is in place. As such it is rewarding to know that there is a new technology that can be used to address all the above challenging applications.
   ECN’s Fiber Optic Blade Monitoring (FOBM) strain sensor, that uses FBGS optical fiber as the measuring element. For monitoring of turbine blade root bending moments

FBGS uses draw tower technology to manufacture their fibre optic grating sensors. This results in a product that is not only mechanically stronger than traditional Fibre Bragg Gratings (>5% strain) making manual handling easier, but due to the unique composition of the glass it can be mounted on intricate structures requiring twists and turns not normally associated with optical fibre based measurement systems.

Furthermore, multiplexing many sensors on a single fibre is possible, thus reducing both the complexity and weight of the installation. As the fibre is immune to the effects of EMI, the range of possible applications where electric sensors are not suitable is vast. It has even been proven to work whilst bombarded with gamma and proton radiation and can operate effectively in temperatures from cryogenic to 200degC.

Perhaps most importantly and unlike electric strain gauged sensors, optical fibre based sensors do not require a recalibration once installed. It is possible to return to them after weeks, months or years and simply plug in an instrument to read the relative change of strain since the last visit.

Through the combination of their unique draw tower manufacturing process and the special coating material supplied exclusively by the Fraunhofer Institute for Silicate Research, FBGS optical fibre is highly suited to industrial sensing applications. The opportunities for manufacturers of sensors and transducers in industries as diverse as medical, composite, metal processing, oil & gas, weighing and wind turbines are now starting to take advantage of this.
