Optical particle counter.

Alphasense has launched a new version of its optical particle counter. The new OPC-N3 retains all of the advantages of its predecessor (OPC-N2) with the added benefit of automatic range switching covering PM10, PM2.5 and PM1. With an expanded measuring range (0.38 to 40 µm), the OPC-N3 is able to measure the particulate fractions of most interest; from the finest of particles up to larger particles such as pollen.

 “This is an extremely important development for manufacturers of air quality monitoring instrumentation,” says Alphasense Director, Arthur Burnley.

“A few years ago, the public was generally unaware of the threat posed by air pollution. However, the many thousands of premature deaths that occur every year in almost every country, have finally caused a high level of media coverage and political interest, and this has led to demands for air quality improvement measures, which in turn have created a need for accurate particulate sensors.

“This bodes well for our customers as the demand rises for small, accurate, reliable, cost-effective particulate sensors.”

The OPC-N3 measures particulates with minimal maintenance using a patented design, providing both particulate matter readings and real-time particle size histograms. As such, the sensor competes in performance with existing analytical units, but at a fraction of the cost.

Hinged frame connector.

Harting has added a new hinged frame module to its established Han-Modular® industrial connector system.

The new Hinged Frame Plus module incorporates a stainless steel spring that holds the frame together in the open and closed positions, as well as a number of other features that have been optimised to make assembling the connector modules easier and more efficient.

Highly visible lettering provides support in this context. All module positions are evident at first glance, while an additional marking with a black triangle indicates the orientation for proper insertion of the modules on the frame.

Insertion of the modules is especially easy since the spring maintains the frame in the open position and the modules fall into a defined support edge. The frame windows are optimised so that they have a funnel-shaped opening with the modules automatically centred when the frames are closed. When locking, a contour fitted to the joint works in tandem with the stainless steel spring to produce a clearly audible click, and holds the frame securely together – meaning that the fixing elements previously used can be dispensed with.

Since the new module is based on the design of the original hinged frame module, it continues to offer the properties of high mechanical stability and full compatibility with the entire Han-Modular® connector range - the market standard for modular industrial connectors.

Despite the variety of over 100 different modules for power, data and signals, all available modules can be used without limitation, and no compromises need be made in terms of mechanical stability.

Miniature object recognition.

The new O300 miniature laser sensors with IO-Link by Baumer are the specialists for the reliable detection of very small objects and gaps. A laser beam which focuses to within 0.1 mm and the high repeat accuracy of 0.1 mm, ensures that objects can be positioned with high precision and follow-up processes controlled exactly.

Thanks to the extremely short response time of less than 0.1 ms, the sensor reliably detects even closely spaced objects, thus allowing fast processes and high throughput rates. A big advantage is the exact alignment of the laser beam to the fixing holes by design (qTarget).  Detection with pinpoint accuracy can be guaranteed over the entire series.

Helping ensure hazardous waste is safe.

Tabib Toxic Waste Services Ltd has purchased a second Tiger handheld photoionisation detector (PID) from Ion Science – leading specialist in gas detection instrumentation for global occupational health and environmental monitoring applications – to ensure the safe export of hazardous waste from a new hazardous waste transfer station in Israel.

Tabib, which repackages and exports hazardous waste materials, is using the intrinsically safe TigerLT instrument to monitor levels of volatile organic compounds (VOCs) in box containers before they are sent to Europe.

Tabib provides comprehensive solutions for all types of waste, from the generation phase to the delivery of waste to its final destination. Since the company was established in 1992, it has become a leader in its field, thanks to the increased awareness of environmental issues and increased enforcement of environmental laws in Israel.

Daniel Stern, Chemistry Technologist at Tabib Toxic Waste Services comments: “Tabib holds an export license for recycling, treating and destroying all types of hazardous waste, in line with the Basel Convention. This means we are authorised by Israel’s Ministry of Environmental Protection to export toxic waste for treatment abroad. We have treatment and destruction facilities outside of Israel that specialise in all types of hazardous waste.

“With the opening of a new hazardous waste transfer facility, we required another PID to monitor VOC levels in box containers being exported to Europe. Our existing Ion Science Tiger VOC detector has proved reliable, accurate and trouble-free so it made sense to use the same brand.

“As we only monitor VOCs, the distributor recommended the streamlined TigerLT as both a functional and cost effective option. We are confident the performance will match the original Tiger instrument as it also incorporates Ion Science’s market-leading PID technology for increased resistance to humidity and contamination.”

Tabib’s skilled chemists are using the TigerLT on a daily basis to check box containers of hazardous waste before they are sent to the port from the waste transfer station. The results are recorded within containerisation reports.

Ideal for conducting environmental surveys, the handheld TigerLT boasts a detection range of 0.1 - 5,000 parts per million (ppm). It utilises a standard two-point calibration protocol and offers an unrivalled industry response time of just two seconds and equally quick clear down.

Both simple to operate and service, the TigerLT allows easy access to the lamp and sensor and the safe replacement of batteries in hazardous environments. The intrinsically safe instrument also meets ATEX, IECEx, UL and CSA standards.

The TigerLT six pin MiniPID detector cell with anti-contamination design dramatically extends run time in the field. Low cost filters and lamps can be easily changed in minutes, minimising downtime.

This instrument also features long life rechargeable Li-ion batteries which give up to 24 hours usage. Fast battery charging allows the instrument to be fully charged in 6.5 hours, while eight hours of use can be achieved from 1.5 hours of charging time.

TigerLT features a protective, removable boot for harsh environments while a large, clear back-lit display allows for easy viewing in any light condition. It is IP 65 rated against water ingress. An integrated torch is designed for directing the instrument’s probe into dimly lit areas. Other features include a loud 95 dB audible alarm and multiple language support. It also has push to log data log option.

Reducing electric vehicle test development times.

Major automotive manufacturers like Subaru are using National Instruments (NI) hardware-in-the-loop (HIL) technology to simulate actual road conditions for electric vehicle testing, eliminating environmental factors to reduce test time and costs.

Traditionally, engineers have conducted vehicle tests using finished cars on test courses or public roads to check the vehicle’s performance and safety response. However, certain limitations, such as weather and fluctuating road surface conditions, can make it difficult to conduct reproducible tests on roads in a timely manner. Moreover, electric vehicles are extremely complex due to their many subsystems, which are all interdependent on each other. This complexity makes the job challenging for automotive test engineers with short development cycles and pressure to limit costs.

To combat these issues, Subaru replaced the roads in the validation tests with a NI HIL simulation solution built on NI PXI products and LabVIEW software. With the HIL system, Subaru can eliminate environmental factors and thoroughly and efficiently test a vehicle’s embedded controller in a virtual environment before running real-world diagnostics on the complete system.

“By using NI PXI products and LabVIEW, we were able to completely implement a customized HIL system in just one to two weeks and develop our software in-house,” said Daisuke Umiguchi, Electrified Power Unit Research and Experiment Dept., Subaru Corporation. “This helped us keep product purchasing costs to around one-third of the cost of adopting solutions from other companies, and, because of our familiarity with LabVIEW, keep our software development costs to around one-sixth of the cost of commissioning an outside developer.”

Subaru further outfitted its vehicle test solution with a controller-driven dynamometer by HORIBA and CarSim vehicle dynamics simulation software deployed by Virtual Mechanics. Together, they produce load conditions equivalent to those generated on actual roads. This driving system transmits the calculated values to the NI HIL system in real time to create closed-loop control between the models on the HIL system and the driving system. As a result, the HIL interaction system can apply the appropriate load to the vehicle throughout the tests.

Subaru plans to use this test system at the final stages of development for electric vehicles as a final quality check, and eventually expand its use for all car types. By adopting this system, Subaru anticipates reducing labor hours by half compared to conventional methods.
