Description
SV 151 Triaxial accelerometer
SV 151 triaxial accelerometer has very high shock resistance, no DC offset effect, very low power consumption and a frequency response down to DC level. For the SEAT transmissibility measurements the small size SV 151 is placed on the vehicle floor in accordance to ISO 2631-1. The sensor’s built-in TEDS memory stores information about the accelerometer sensitivity that is automatically transferred to SV 106 instrument.
