SV38V – Seat Accelerometer
SV38V Seat Accelerometer is a triaxial Whole-Body seat accelerometer based on MEMS transducers dedicated to SV106 instrument for Human Vibration measurements according to ISO 2631-1 requirements both on a seat pad or seat back.
The SV38V uses low voltage and consumes much less energy than IEPE accelerometers extending battery life time of SV106 instrument. The built-in TEDS memory stores information about the accelerometer sensitivity that is automatically transferred to the SV106 vibration analyser helping to avoid configuration errors.
A full ISO 8041 in-situ calibration check for before and after measurement is possible using the SV111 portable vibration calibrator.
Features:
- Meets ISO 8041 and ISO 2631-1
 - Dedicated to SV106
 - Low-power consumption
 - Robust technology
 - TEDS memory
 - Low price
