Monitor Vibration Levels of Industrial Equipment

Perfect for monitoring the vibration levels of industrial equipment, the Sensaphone Vibration Sensor helps you detect unusual operating conditions, so you can address problems early. Used with any Sensaphone device that accepts a 4-20mA input signal, the sensor permanently mounts to your equipment and continuously monitors real-time RMS vibration velocity to provide an analog output of the velocity through the Sensaphone. It connects to the Sensaphone with the included cable.

  • Monitor vibrations from 0 to 25 mm/s (RMS)
  • Ideal for monitoring industrial equipment
  • Works with any Sensaphone that accepts a 4-20mA input signal


  • Vibration Sensor
  • Cable, 5m

NOTE: Requires a 24VDC power supply, sold separately. Optional magnetic mounting foot (FGD-0303-MOUNT) also sold separately.
