USB Programmable Smart Vibration Switch

August 18, 2010
The switch is 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 for use in hazardous environments, the switch is hermetically-sealed and mounts with a single stud like a sensor. The unit includes an embedded piezoelectric accelerometer for accurate measurement, monitors vibration velocity for more consistent results, and provides the reliability not found in mechanical switches. Also offers a remote reset capability and USB programmable threshold and time delays to avoid false trips.
