This Series 686B USB program-mable smart vibration switch is ATEX-approved. It is designed for continuous protection of cooling towers, fin fans, pumps, HVAC systems, or other critical machinery operating in hazardous areas.
Also CSA approved, the hermetically sealed instruments mount with a single stud like a sensor. They include an embedded piezoelectric accelerometer for accurate measurement and to monitor vibration velocity for more consistent results than mechanical types.
Series 686B is fully user programmable via USB as a drop-in replacement for most popular mechanical vibration switches. It requires two wires and can replace older switches without need for additional cable runs. The smart switch is also cited to cost less as an alternative to electronic vibration types.
