Ultrasonic sensor.

The new model P53-80-D18 from Hoffmann + Krippner is a compact (45mm long and 18mm diameter) ultrasonic sensor. It is one of the smallest ultrasonic sensors on the market worldwide and is designed for use in harsh environmen­tal conditions as well as in hygienic applications.

Due to the special housing construction made of V4A stainless steel (1.4404) with a roughness depth of 0.6μm, the P53 STEEL HEAD is well suited for use in harsh environments such as dust, moisture and water vapor. As the sensor and its mounting assembly can be sanitized with strong cleaning materials, the P53’s real world applications include manufacturing, food and chemical processing, medical, agriculture, packaging, etc. It can be used for a variety of distance measurements as well as level measurement, presence detection, detection of moving objects, counting objects and checking for completeness.

According to Jens Kautzor, CEO of Hoffmann + Krippner, “The P53 is perfect anytime a machine requires a small profile, reliable and cost-effective ultrasonic sensing solution that is easy to install and to clean.”

The new miniature P53 provides a range of up to 800 mm. The high temperature range of up to + 80 °C opens up a wide range of ap­plications.

The EHEDG certified model is equipped with an integrated cable screw connection, ensuring best hygiene for food and beverage as well as bottling and packing industries. The industrial model includes a M12 connector with power supply, signal output and teach in. It can be mounted with two Teflon nuts that provide acoustic decoupling. The P53 can be configured via the M12 connector cable. In addition, optional external hold/sync switches are available.

The ultrasonic sensor P53-D18, together with the support clamp P53-SC-D18-5-EHEDG, meet the “hygienic equipment design criteria” released by the EHEDG for “Type EL, Class I Aux” in terms of the mechanical design, materials and surface qualities. For areas with strict hygienic requirements, the ultrasonic sensor should be used with the provided support clamp P53-SC-D18-5-EHEDG. The usage of ECOLAB certified materials provides resistivity against cleaning agents like P3-topactive OKTO, P3-topactive 200, P3-topax 52, P3-topax 66 and P3-topax 990.

Breaking a torque tradition.

TorqSense Rotary Torque Sensors, made by Sensor Technology Ltd, are unlike traditional slip ring transducers. They use a simple non-contact radio link for collecting real-time torque signals, letting machine builders and control engineers can do away with expensive and temperamental slip rings. Thus simply mounting the sensors and checking the radio connection is all that is required to set up a TorqSense.

Electronics convert the data stream directly into engineering outputs, such as torque, speed, power and angle. Serial and USB interfaces make TorqSense directly compatible with PCs and other user-friendly features include built-in peak torque sampling, storage and torque averaging, and a self-diagnostics test package. The electronics can be provided, integral with the main unit or in a separate housing, to suit individual applications.

To achieve the non-contact operation that makes the TorqSense transducer range unique, SAW (surface acoustic waves) devices are used as frequency-dependent strain gauges to measure the change in resonant frequency, caused by strain experienced in the driveshaft. This measurement is directly related to the torque experienced in the rotating machine element.

In use, SAW devices are mounted onto the shaft and their output signals are transmitted by a low-power radio frequency (RF) coupled to an adjacent pick-up, which interprets the signals and converts them into a torque measurement readout or feeds them on into a PC for further calculation.

In a SAW sensor, the surface waves are produced by passing an alternating voltage across the terminals of two interleaved comb-shaped arrays, laid onto one end of a piezoelectric substrate. A receiving array at the other end of the transducer converts the wave into an electric signal.

The wave frequency is dependent upon the spacing of the teeth in the array and the direction of wave propagation is at right angles to the teeth. Therefore, any change in its length, caused by the dynamic forces of the shaft's rotation, alters the spacing of the teeth and hence the operating frequency. Tension in the transducer reduces the operating frequency while compression increases it.

To measure the torque in a rotating shaft, two SAW sensors are bonded to a shaft at 45° to the axis of rotation. When the shaft is subjected to torque, a signal is produced, which is transmitted to the adjacent stationary pick-up via the capacitive RF couple comprising two discs, one of which rotates with the shaft, the other being static.

The frequency of the oscillation used is typically 200MHz. The frequency-basis of the TorqSense concept gives a wide bandwidth and the susceptibility to electronic interference, common with other analogue-based techniques such as inductive devices, is eliminated.

Monitoring machine conditions.

Bosch and Harting have pooled their expertise to produce the first Plug&Play IoT kit for industrial applications with IP54 protection, available on the market. It quickly and easily allows digital condition monitoring for any type of machinery.

Digital condition monitoring using physical measurements such as temperature and vibration is an efficient means of permanently monitoring and improving the system availability of machinery and plant. It enables changes in machine behaviour to be identified and the appropriate action taken. However, selecting, installing and integrating suitable components in existing infrastructure can sometimes be very costly, as production plants turn to trained IT specialists for support. The IoT starter kits previously available on the market are suitable for first prototyping but are not designed for long-term use in an industrial environment.

With the MICA® CISS Industrial IoT Kit, developed in cooperation with Bosch Connected Devices and Solutions and Harting Technology Group, an IoT solution is now available which is operational within a day and supplies initial data immediately. The kit comprises a CISS (Connected Industrial Sensor Solution) multi-sensor unit by Bosch and the MICA® Edge Computing System by Harting.

Only a few steps are necessary to start the application. The small CISS sensor unit can be attached to any surface (IP54) and detects up to eight physical factors, including temperature, humidity, vibration, change of position, pressure, light, magnetic field and acoustics. The robust MICA® mini-computer can also be installed alongside the machine (IP67) without the need for a control cabinet. MICA® is connected to the sensor unit and the local network via industry standard connectors. Immediately after start up, the sensor data is provided in MQTT format and displayed in the web browser, via the integrated Node-RED dashboard. Data can be analysed and stored in any IT systems or IoT platforms and a connector for Microsoft Azure Cloud is already pre-installed. Local data storage is also possible as MICA® can be supplemented with various database software to meet the specific requirements.

Vehicles emissions live at show!

Visitors to AQE 2018 in Telford (GB) will be able to view live emissions data from vehicles travelling on a road close to the Telford International Centre, where the event will take place (21-22nd Nov.) Ricardo plc, a global strategic engineering and environmental consultancy, will operate the monitoring equipment, providing a live feed into their AQE exhibition stand number No. 74.

“This is very exciting,” comments show organiser Marcus Pattison. “Vehicles are being blamed for urban air pollution, so this will be a great opportunity to see ‘real-world’ emissions rather than car manufacturers’ data. Entry to the AQE 2018 exhibition is free of charge to pre-registered visitors so whilst the event was created for air quality professionals, there is no reason why members of the public or local pressure groups should not also attend.”

Ricardo and its technology partner, OPUS RSE, use state of the art vehicle emission remote sensing equipment to accurately measure real-world driving emissions from large numbers of vehicles, under actual driving conditions, in a short space of time. The equipment is portable and will be configured to measure emissions of the pollutants of most interest, namely nitric oxide, nitrogen dioxide, particulate matter, hydrocarbons, carbon monoxide and ammonia.

The data gathered provides local insight necessary to inform the cost-effective design of low-emission policy and helps to ensure that mitigation measures focus only on the most polluting vehicle types.

The world’s leading manufacturers of air quality monitoring equipment will display the latest technologies at the event, and with registrations up by 21% AQE 2018 is set to be busier than ever. In addition to the exhibition there will be a comprehensive programme of free workshops as well as conferences on Clean Air Zones, the Medium Combustion Plant Directive, air quality legislation and Brexit, emissions from organics recycling, and air quality monitoring and improvement measures.

Handheld control valve tester.

Control valve testing has meant using complicated testers that require extensive training, the removal of the valve, and often one-to-two hours of test time on the bench. The new Fluke™ 710 mA Loop Valve Tester allows technicians to source the 4-20 mA signal while it interrogates HART data to collect critical information about the valve’s position and status, providing quick checks of control valves while they are in place. With built-in test procedures and an intuitive interface, the Fluke 710 allows technicians to quickly and easily perform valve tests, while the valve test quick-check results provide at-a-glance diagnostics to make faster maintenance decisions.

With the Fluke 710 tester’s built in HART communication function, technicians can source a 4-20 mA signal to cause the smart control valve to move, while simultaneously interpreting the valve’s HART feedback signal to determine whether the valve is moving to the expected position. In addition to positional information, the measured pressure delivered from the valve’s internal I/P (which moves the valve) can be seen with the HART communication protocol.

The Fluke 710 features pre-configured valve tests for reliable and repeatable testing. The built-in routines include:

  • Manually changing the mA signal and viewing the HART position and pressure variable information.
  • Full range ramping of the mA signal from 4 to 20 to 4 mA while recording the 0-100-0 percent position, or the pressures applied that move the valve from 0-100-0 percent.
  • Stepping the mA signal on the input to the valve in steps and evaluating the valves response to the mA input changes.
  • Speed tests to determine how fast the valve can open or close.
  • Bump and partial stroke tests that help test valves over a portion of their range so they can be tested in a live process.

Test results are stored in the memory of the Fluke 710 where it can be uploaded to the included ValveTrack™ analysis software. ValveTrack allows users to

  • Upload and plot logged valve tests taken in the field.
  • Compare previous uploaded tests to recent tests.
  • View valve test history by HART Tag ID.
  • Export valve test data to CSV for additional analysis in Microsoft Excel.

Vision on view!

The 2019 UKIVA Machine Vision Conference and Exhibition is scheduled for 6th June at the Marshall Arena in Milton Keynes (GB). This will be the third year that the event has been run. It is becoming increasingly popular with attendance figures in 2018 up 17% compared to 2017.

The event will follow a similar format to previous years, with a comprehensive program of technical seminars supported by an exhibition featuring vision component manufacturers, vision component and system distributors and systems integrators from around the world. However, the 2019 Conference will feature an additional theme, covering applications of vision in automation and robotics.

Chris Valdes, UKIVA event organiser and business development manager for the PPMA (Processing & Packaging Machinery Association), said: “At the event in 2018, a number of exhibitors included robots and cobots in their displays, which provided a great deal of interest. There have also been recent developments in the communication standards for machine vision and robots for use in Industry 4.0, making technical seminars on vision, robotics and automation even more relevant.

“UKIVA has a natural affinity with the combined use of vision and robotics as BARA (British Automation & Robotics Association) is, like UKIVA, part of the umbrella PPMA (Processing & Packaging Machinery Association) and many of our members have an active interest in BARA as well."

While the Conference sets out to cover the key issues in machine vision, such as deep learning and embedded vision, as well as Industry 4.0, there are plenty of presentations that cover basic vision technology.

The previous events have attracted large numbers of people who wanted to learn more about the fundamentals of vision technology, coupled with those who were keen to explore the latest developments. Other key topics that will be covered in-depth at the Conference will include: 3D Vision, Optics and Illumination, Vision Innovation, Systems and Applications, and Camera technology.

Keynote speakers at the two previous events have also attracted large audiences, and details of the 2019 keynotes, together with the conference program and information about the exhibition, will be published on the Conference website when they have been finalised.
