Patented technology for precise position detection

| By Chemical Engineering



The new PMI F90 inductive positioning system (photo) works with a patented multi-coil system. The absolute position of the actuator is precisely detected from the measuring signals of a single coil. In addition to sending the analog 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, says the manufacturer. Certified versions of the PMI product family allow the system to be used in ATEX Zone 2/22 (3G nA, 3D tc) hazardous locations. The compact design allows these sensors to be installed in even the tightest of spaces, while the rugged metal housing protects them from external influences. IP67 protection and a temperature rating of –25 to 85°C ensure reliable positioning in outdoor environments. — Pepperl+Fuchs GmbH, Mannheim, Germany
