The accelerometer can easily be attached to the handle of the vibrating tool being measured. The sensor’s TEDS memory stores information about calibration factor limiting the risk of configuration errors. The accelerometer is supplied with three different diameter fixing clamps to conveniently match the grip of the vibrating tool being measured. SV 150 offers more robust and lower cost alternative to a traditional piezo-electric accelerometer.

  • Designed for hand arm vibration measurement
  • Uses MEMS transducer technology
  • Tool mounted using adjustable clips
  • TEDS memory for automatic instrument calibration
