The Model 832M1 is a low cost, board
mountable triaxial accelerometer. Featuring
stable piezo-ceramic crystals, the accelerometer
incorporates full power and signal conditioning
with a maximum current consumption of 22
micro-amps. The model 832M1 is available in
±25g to ±500g ranges and provides a flat
frequency response up to greater than 6kHz.
The standard model 832 offers the same
envelope with a lower maximum current
consumption of 4 micro-amps.
