Triaxial accelerometer SV 107B

MEMS

SV 107B is a triaxial hand-arm vibration accelerometer dedicated to measurements according to ISO 5349-2 with SV 103 hand-arm vibration dosimeter. The SV 107B has in-built force sensors to detect the contact and to exclude periods of time when the tool is not in use. For in-situ checks and periodic verification of the SV 107B the SA 105B adapter (option) is necessary. The accelerometer has TEDS memory that remembers the calibration factor transferred to SV 103 instrument. Accelerometer is supplied with three adapters to perfectly match the grip of different vibrating tools. Each adapter includes an adjustable rubber strap for firm and comfortable attaching the accelerometer to the human’s hand. This solution significantly limits disturbances to the operator who doesn’t have to worry about holding the accelerometer.
