Electronic Vibration Switches

Electronic vibration switches use a Built in precision accelerometer to accurately monitor vibration levels. An electronic switch consists of an accelerometer, circuit board and one or more electromechanical or solid state relays for alarm and shutdown protection. The internal circuitry monitors the sensor’s vibration level and compares it to a preset threshold or alarm value. When the vibration level exceeds this threshold, the relay is then activated. A typical electronic vibration switch has several advantages over a mechanical unit. It has no moving parts, is more reliable and has a much higher degree of accuracy and repeatability. Time delays can be used to avoid false trips during switch power up, equipment startup, operational changes and the chance occurrences of short term vibration increases.

Highlights:

  • Offers two set points with individual alert and alarm relays
  • 4-20 mA output signal for vibration monitoring
  • Explosion proof models available
