M7 Acceleromer

M7 Acceleromer specifications:


Sensitivity: 180 mV/g differential +/- 1% typical

Frequency range: 0 to 2300 Hz

Damping factor 0.7 typical

Polarity: upward acceleration produces positive Voltage

Built-in test: "OK" is +20 V differential when dual outputs match within 5% full linear scale, measured between 0.7 and 130 Hz. Otherwise "OK" is -1 V differential


Dynamic Range:

Linear sensitivity between +/- 100 g's full linear scale

Over-range: Reduced sensitivity beyond +/- 100 g's

Total dynamic range without clipping: +/- 450 g's
