WHOLE BODY MEMS ACCELEROMETER
The SV 151 is a low cost tri-axial accelerometer based on MEMS transducer technology. Fully complying with ISO 8041, it has a built-in TEDS memory that keeps information about the accelerometer sensitivity that is automatically transferred to the vibration analyser being used.
A full ISO8041 in-situ check for before and after measurement is possible using the SV111 portable vibration calibrator and dedicated SA40* adaptor.
The SV 151 accelerometer is designed for SEAT transmissibility measurements. Its small size enables the SV 151 to be placed on the vehicle floor accurately and according to ISO2631-1 requirements.
The SV151 is a tri-axial accelerometer enabling SEAT transmissibility measurements to be measured in all 3 axes simultaneously. It can be used with any instrument that supports MEMS technology such as the SV 106 multichannel human vibration analyser.
