TEST & MEASUREMENT PRODUCTS INDUCTIVE POSITION MEASUREMENT
The new PMI F90 inductive positioning system from Pepperl+Fuchs can precisely detect the absolute position of one actuator as well as the distance between two. Thanks to IO-Link technology, the system has comprehensive communication functionality and is equipped for Industry 4.0 applications. The new PMI F90 inductive positioning
system works with a patented multi-coil system.
The absolute position of the actuator is accurately detected from the measuring signals of a single coil. In addition to sending the analogue position signal, switch points can also be defined. The sensor can detect two actuators as well as the distance between them, meaning that dynamic positioning tasks can be completed with the smallest amount of measuring technology. The device enables continuous data flow due to its IO-Link interface.
This makes it particularly suitable for applications featuring Industry 4.0 architecture. Event logs, error messages, signal quality data, device status, and operating hours can all be read directly by the IO-Link master. The PMI F112 and PMI F166 sensors from this product family are
available for confined areas and harsh environments. The compact design allows these sensors to be installed in even the tightest of spaces while the robust metal housing protects them from external influences. The advantages of the inductive measuring principle apply to all devices: non contact, low-wear and maintenance-free, dirt-resistant, and resistant to interference. All steel components or objects can generally be used as actuators since the inductive system is not reliant on a magnetic actuator.

National Instruments (NI) has launched the Vehicle Radar Test System (VRTS). Engineers can use the VRTS to test 76–81GHz radar technology from the R&D lab through to high-volume production tests and from individual radar sensors to integrated advanced driver assistance systems (ADAS). The VRTS is available through select NI Alliance Partners who provide advanced system integration and support. The VRTS combines NI’s mmWave front end technology, a PXI Vector
Signal Transceiver (VST) and application-specific software. The VRTS integrates a 76–81GHz vector signal generator/analyser designed for dynamic obstacle generation and comprehensive RF characteristic measurements. Using a more comprehensive approach to radar test that includes both traditional and hardware-in-the-loop (HIL) test techniques, engineers can deliver more robust autonomous driving technology to comply with evolving regulatory requirements. The VRTS scales from a base configuration that can emulate
two obstacles to sophisticated configurations that can emulate four independent obstacles per PXI chassis. Key VRTS attributes include the ability to simulate Doppler effect velocity of up to 250km/hr, minimum obstacle range of 4m, and object distance resolution down to 10cm. The VRTS includes both object simulation capabilities and the radar measurement suite. In addition, engineers can take advantage of the flexibility of the
software to use the VRTS to simulate scenarios ranging from a pedestrian walking across the street to lane-change driving scenarios. VRTS software flexibility is a key benefit of the system as engineers can easily adapt to rapidly evolving regulatory environments. The VRTS empowers engineers to build smarter, customised test
systems. Users can also benefit from the productivity of the LabVIEW, VeriStand and TestStand software environments.
