FEATURE TEST & MEASUREMENT


TESTING BRAKE DISCS A


market leading brake disc supplier has been supplying high quality products to


the UK automotive market for over 50 years. The company recently contacted Hydrotechnik UK after viewing its portfolio of test rig solutions online. From customer brief to commissioning, the user


controlled hydraulic test rig measures parameters: disc thickness and disc thickness variation of the customer’s series of brake discs. Enclosed in 316 stainless steel, the test rig is


designed for industrial testing. The rig is fitted with polycarbonate, ensuring operators remain safe during testing. To measure the thickness of the brake discs,


Hydrotechnik UK installed sensor heads that carry out a four-point measuring system to +/- one micron accuracy. Precise inductive RPM sensors display the speed of the brake disc from zero to 100 RPM. Both sets of data help inform the customer of the precise variations of brake discs under a given speed to specific tolerances.


Test data can be seamlessly exported via USB, enabling the engineer to have data at their finger tips which can be graphically presented through Microsoft Excel. After delivering the test rig to the customer,


Hydrotechnik UK trained all operators on the software and hardware procedures. It


has now become an integral part of the customer’s manufacturing facility and are now increasing their production capacity and throughput.

5G MMWAVE TEST PLATFORM HANDHELD


The Warwick Manufacturing Group (WMG) at the University of Warwick, recognising the monumental impact that 5G is and will continue to have on wireless communications, has recently announced an upgrade to their lab to include 5G mmWave technology. This upgrade has been possible because of a WMG Centre HVM Catapult award and equipment collaboration from NI. The WMG will be using our mmWave Transceiver


System to expand their research from the traditional sub 6GHz frequencies into the new mmWave spectrum and unlock significantly wider blocks of contiguous bandwidth. More bandwidth means higher data throughputs, which is already beginning to lead to a variety of new applications. For WMG, their specific interest is researching how mmWave communications can enable connected and autonomous vehicles (CAVs).


ENABLING THE FUTURE OF AUTOMOTIVE CAVs will require 5G technology to be truly successful. Existing LTE systems are lacking for several reasons, most importantly high latency and lack of data throughput. Since Vehicle to Vehicle (V2V) communication needs to be fast in order to be meaningful, latencies above the 1ms stated goal of 5G will not give the vehicle enough time to react. Large bandwidths are necessary to send and


receive the massive amounts of data potentially sent between sensors, the cloud, and other vehicles. Why the cloud? If all processing and sensor hardware lives on the vehicle itself, updates become extremely difficult. (Vehicles are not upgraded every two years like a cell phone.)


TEST PRODUCTS


RS Components has announced the availability of three FLIR handheld units that feature the company’s Infrared Guided Measurement (IGM) technology. The DM285 is an all-in- one industrial True-RMS digital multimeter and thermal imager that enables users to find hot spots or temperature anomalies. The CM275 is a clamp meter that


But, if they can upload and download data from the cloud, this issue could be resolved. The processed data could then be downloaded by any connected vehicle, reducing the need to upgrade hardware inside the vehicle itself. WMG’s Connected and Autonomous Vehicles research team are already working with a range of industrial partners on connectivity, verification and validation, and the understanding and optimization of user/customer interaction with driverless technology. This new facility will further enhance WMG’s vison to be the United Kingdom’s “go-to” CAV development platform providing unrivalled research and testing that will accelerate product introduction, infrastructure design and implementation.

combines thermal imaging with electrical measurement, providing a reliable way to identify hot spots and overloaded circuits from a safe distance. The third device is the DM166, which is a multimeter with a built-in 80 x 60 thermal imager, ideal for locating temperature anomalies, along with a feature-packed multimeter for troubleshooting and diagnosing issues in either high- and low-voltage applications. FLIR has also launched two new


multimeters: the DM62 and DM66. The units offer measurement of voltage, current, frequency, capacitance, and temperature, as well as impedance for the DM66.
