Multislot Ethernet chasses.

National Instruments (NI) have announced the release of two new multislot Ethernet chassis at their annual NI Week in Austin (TX USA) . The cDAQ-9185 and cDAQ-9189 introduce new time-based synchronization built on the latest Ethernet standards, furthering NI’s efforts in Time Sensitive Networking (TSN) and rugged CompactDAQ hardware for distributed measurements.
The nature of physical systems test is rapidly changing as measurement systems migrate from the control room to closer to the device under test. While this shortens installation time, reduces the cost of sensor wiring and improves measurement accuracy, it creates challenges with synchronization and systems management, especially using today’s industrial networking technologies. NI is actively working to help define TSN, the next evolution of the IEEE 802.1 Ethernet standard, to deliver distributed time synchronization, low latency and convergence of time critical and general networking traffic. The cDAQ-9185 and cDAQ-9189 provide tight time synchronization with TSN to simplify and improve scalability of synchronized, distributed systems.

Features and benefits include:
• Precise synchronized timing over the network, which eliminates the need for lengthy, physical timing cables and ensures tightly synchronized measurements for accurate analysis.
• Simple daisy chaining through an integrated network switch for quick setup and expansion in distributed applications.
• Reliable operation in harsh environments with -40° to 70° C operating temperature range, shock resistance up to 50 g and vibration resistance up to 5 g.
• Software abstraction through the NI-DAQmx driver that automatically synchronizes multiple chassis for simple programming.

“These new chassis automatically synchronize measurement data using network-based time. This allows accurate synchronization over long distances, which greatly simplifies customer setup and systems management of high-channel-count and distributed systems,” said Todd Walter, chief marketing manager of the DAQ and embedded lead user team at NI. “This new, innovative method of synchronization combined with the signal processing libraries in LabVIEW system design software helps engineers quickly collect and analyze results, which drives faster test completion and higher efficiency.”

For more than a decade, engineers have used CompactDAQ with LabVIEW to quickly customize DAQ systems to meet their application needs. With NI’s investment in the latest technologies for synchronization and communication, the new CompactDAQ chassis are equipped to meet the current and emerging needs of distributed test and measurement applications, delivering high-performance, rugged DAQ systems that can acquire data from highly distributed sensors.

Metal-seated ball valves.

Emerson introduces the Fisher™ Z500 line of metal-seated ball valves to its severe service portfolio.

Fisher Z500 metal-seated valves from Emerson, are engineered to withstand higher temperatures, pressures, and more erosive conditions than a standard on/off ball valve, providing increased reliability and protection of critical assets in demanding applications. A patented, bi-directional sealing design offers a unique solution to process back pressure and shutoff requirements in both flow directions, safeguarding control valves and other equipment in the line.

Fisher Z500 valves are designed with an integral metal seat and self-energised metal body gasket to help eliminate leak paths and withstand extreme temperature changes. Live-loaded packing, side-mounted brackets, and fixed centrelines help reduce side loads on the packing and decrease overall wear for a longer service life. This addition of on/off valves to the Fisher portfolio complements the existing control valve offering and helps ensure seamless integration between products.


“The combination of isolation valves and control valves gives our customers the opportunity to work with a single solution-provider to achieve the process protection and reliability they need for their critical applications,” said Kevin Meyer, president of Emerson’s Fisher Valves & Instruments business. “We feel that adding another quality product to our wide-reaching network of Emerson sales offices and service centres around the world will not only give our customers a comprehensive valve assembly, but the local support to go with it.”

Angular position sensors.

ZF Switches & Sensors can now offer designers a complete range of angular position sensors based on Hall Effect technology which responds to magnetic fields generated by a (rare-earth) magnet. The sensors provide a linear change in voltage output corresponding to the rotation of the actuator.
Mark Mills, Distribution Sales Manager for ZF Switches & Sensors, comments, "ZF has vast experience of supplying sensors to the automotive market and our range of industrial sensors provide cost effective, high reliability sensing solutions for the growing industrial sensing market."

The ANG series of sensors are non-contact angular position sensors which provide a linear change in the voltage output corresponding to an angular rotation of the input shaft. One or two independent (non- or semi-redundant) outputs are available. The sensors offer rotation up to 360°, can replace potentiometers and have a 12 bit resolution. Custom programming is available for angle range, slope and PWM output. ANG sensors are waterproof to IP68, have a temperature range from -40 to +140° and have wire termination. The compact design has no mechanical interface ensuring there are no parts to wear out or jam.

Typical applications include position sensing, throttle-by-wire, steering, gear selection, and outboard trim sensing on industrial vehicles, fork lift trucks and agricultural trailer hitching.

The ZF AN1 sensors family are angular position sensors with an integral magnet with sensor housing and mate with a Delphi Metri-Pak 150 connector. They offer a nominal rotational range of 120° with counter-clockwise rotation. The sensors are mechanically tested to 10 million cycles, meet IP67 have an electrical operating range 5°to 85°C and operating temperature range from -40 to +125°.
The completely encapsulated assembly is suitable for printing equipment and rough terrain applications including farming machinery

The AN8 sensor is available with wire termination or Delphi Metri-Pak 150 connector. The IP67 rated device has an operating temperature range of -40 to +125°C, an angular rotation up to 360° and can be used to replace potentiometers. Having no mechanical interface ensures high reliability as there are no parts to wear out or jam.

Applications include fork lift truck position sensing, steering-by-wire and foot pedal control of throttle and brake for golf and utility carts

The final model in the ZF angular position sensor range is the AN9 which offers redundancy for safety-critical applications an angular rotation of up to 360°, wire termination, IP67 rating and an operating temperature range of -40 to +125°C.

An example of a design requiring redundancy for safety purposes is the steering column of forklifts where the rotation angle of the steering column needs to be detected to justify the wheel position of the vehicle. Other applications include steer-by-wire, position sensing and foot pedals for throttle and brake control.

Heated humidity sensors.

The HMC03M humidity sensor from E+E Elektronik is dedicated for use in radiosondes and weather balloons. The sensor is characterized by a short response time even at low temperature. An integrated heating resistor ensures an excellent measuring performance under condensation and icing conditions. This makes the sensor ideal for weather observations in the upper atmosphere.

The sensor combines on a silicon substrate a capacitive relative humidity (RH) sensor and a heating resistor. By heating, the sensor quickly recovers after condensation or icing, which leads to a very good measuring performance even under extreme weather conditions. Another key feature of the HMC03M is the short response time at very low temperature. As a result, the HMC03M is ideal for use in radiosondes to measure humidity in the upper atmosphere.

The 5.85 x 2.85 mm small SMD sensor is appropriate for automatic assembling with subsequent reflow soldering. HMC03M is available on tape and reel of 500, 1000 or 2500 pcs.

E+E Elektronik’s product range for meteorology also includes probes and transmitters for highly accurate humidity and temperature measurement. The sensing elements of these devices are well protected from pollution and corrosion by the proprietary E+E coating. This leads to improved long-term stability and a longer lifetime, two essential criteria for long-term use in weather stations.

• E+E Elektronik products are marketed in Ireland by Instrument Technology.

The secret is better control.

Over the last fifty years, almost none of the productivity gains in manufacturing have come from better chemistry or better design, or even better management and financial controls. Rather, those gains have come from better automation and control of the processes: continuous, batch, hybrid , and discrete. The secret to making manufacturing sustainable is better control.

So, why aren't the theories that have led to enormous gains in productivity being used above the plant level? This book, Real-Time Control of the Industrial Enterprise*, from the authoritive pens of Peter Martin and Walt Boyes,  explains both why not and how better controls can be applied to the supply chain, and to enterprise financial management.

This book provides engineering and technology managers the insight and tools for achieving a fully integrated automated manufacturing enterprise, from the technical and engineering side to the business management side. It is particularly helpful to readers seeking to bring the non-technical parts of a manufacturing operation - customer service, cost and financial management - in line with the already-automated production, inventory management, and plant management.

The reader will learn: how to use the principles of real-time process control to manage and measure your manufacturing business more effectively; how to achieve much greater speed of information transfer for improved control over supply chain and distribution; and how totally integrated inventory control, automated manufacturing, automated customer service, and smart pricing control - and ultimately lead to higher profits.

Miniature triaxial accelerometer.

The new Type 8766A lightweight, triaxial accelerometer from Kistler Instruments uses the, patented PiezoStar® crystal developed by Kistler to provide ultra-stable performance with very little sensitivity deviation with temperature changes. Over a temperature range of -50°C to +165°C a PiezoStar® sensor has a sensitivity deviation with temperature which is over thirty times better than a similar quartz sensor. The Temperature Coefficient of Sensitivity of a quartz triaxial accelerometer is 0.18 %/°C, compared with only 0.005 %/°C for a 250g measurement range for the new PiezoStar triaxial accelerometer.

The new accelerometer has been designed specifically to bring these unique properties to applications demanding high accuracy measurements in varying temperature up to 165°C. The small cubical, hermetic titanium housing has threaded mounting holes on each of three sides to facilitate calibration and simplify installation for tests whilst the low mass of only 4g reduces any influence on the test structure. The Kistler PiezoStar® shear element design provides a flat frequency response over a wide operating frequency range and extremely low sensitivity to temperature changes.

The IEPE sensor combines the PiezoStar® crystal with high gain, integral, hybrid microelectronics to achieve very low sensitivity variation over the wide operating temperature range, compared to other sensing element designs, and high immunity to base strain errors. The Transducer Electronic Datasheet (TEDS), embedded in the chips integrated within the IEPE sensor, enable data acquisition systems to automatically recognize the sensor specification and so reduce set up time, minimise risk of human errors and eliminate the need for manual point-to-point connection identification.

Five variants cover the measurement range from ±50g to ±1,000g all with a 100% overload capability plus a high temperature option for temperatures of up to 165°C. In contrast to ceramic and quartz, the extremely stiff piezoelectric crystal sensing element offers a flat frequency response with no slope across the entire useable frequency range of 0.5 to 20,000 Hz.

The accelerometer uses a welded titanium construction for low mass and an industry standard 4 pin connector, as well as a mini 4 pin connector option for lower mass and wider frequency operation. All variations provide reliable measurements and long-term stability, especially at higher operating temperatures. The miniaturized light-weight measuring element in a hermetic titanium housing which has threaded mounting holes on each of the three axes to simplify cable connection and minimise unwanted cable loops. A range of ground isolated mounting bases are available with adhesive, threaded and magnetic mounting options and an integral silicone cable variant is available for underwater vibration testing at up to 10 bars (150 psi).

With its extremely wide and flat frequency response, the unique Type 8766A accelerometer from Kistler instruments is ideal for use in modal and durability testing applications at widely varying temperatures.
