PCB Piezotronics' 686B01 series vibration switch has been ATEX approved for use in hazardous environments. The EX686B01 is suitable for 24/7 continuous protection of cooling tower fans and gearboxes, fin fans, motors and pumps, HVAC systems, wind turbines and other critical machinery operated in hazardous areas.

Meeting ATEX Ex nL IIC T3 approval requirements for use in hazardous environments, the EX686B01 is hermetically sealed and mounts with a single stud like a sensor. This smart vibration switch includes an embedded piezoelectric accelerometer for accurate measurement and monitors vibration velocity for consistent results.

It also offers a remote reset capability and USB programmable alarm threshold, and time delays to avoid false trips.
