VIBRATION SENSOR

  • Two switching outputs for pre-alarm and main alarm
  • Integrated history memory with real-time clock to monitor, display and record values
  • Scalable analogue current output for vibration velocity
  • Analogue input can be used for monitoring another measurand
  • Parameter setting and visualisation directly on the device or optionally via the parameter setting software
