Smart vibration switch for use in hazardous areas

21 September 2010

IMI Sensors, a division of PCB Piezotronics has announced ATEX approval of the Series 686B USB programmable smart vibration switch, designed for 24/7 continuous protection of cooling towers, fin fans, pumps, HVAC systems, and other critical machinery operated in hazardous areas.

Meeting ATEX and CSA approval requirements, the Series 686B is hermetically sealed and mounts with a single stud like a sensor. This smart vibration switch includes an embedded piezoelectric accelerometer for accurate measurement, monitors vibration velocity for more consistent results, and provides the reliability not found in mechanical switches. Series 686B also offers a remote reset capability and USB programmable threshold and time delays to avoid false trips.
