Triaxial accelerometer SV 150

MEMSelectric

SV 150 is a tri-axial accelerometer designed to be used with the SV 106 human vibration analyser to provide a dedicated instrument for measurements according to ISO 5349-2. 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.
