The built-in TEDS memory stores information about the accelerometer sensitivity that is automatically transferred to the SV 106 vibration analyser helping to avoid configuration errors. By ISO 2631-1, seat accelerometers such as the SV 38V are placed on the operator’s seat, either on the seat backrest or on the seat cushion. The use of an SV 111 vibration calibrator is recommended for in-situ calibration checks. SV 38 is based on MEMS transducers which means it uses less power and is more robust than piezoelectric sensors.
A full ISO 8041 in-situ calibration check for before and after measurement is possible using the SV 111 portable vibration calibrator.
The SV/38V number of axes is 3 (triaxial). At 15.915 Hz, its sensitivity is 50 mV/(m/s2). The measurement range is from 0.01 ms2 RMS to 50 ms2 PEAK in the frequency range of 0.1 Hz to 100 Hz.
Features include:
- Meets ISO 8041 and ISO 2631-1
- Dedicated to SV 106
- Low-power consumption
- Robust technology
- TEDS memory
- Low price
