Model 834M1 Accelerometer
Triaxial Piezoelectric
Accelerometer
<22µA Current Consumption
Wide Bandwidth to 6kHz
Circuit Board Mountable
The Model 834M1
is a low cost, board
mountable triaxial accelerometer designed for
high amplitude embedded shock applications.
The accelerometer features a maximum
current consumption of 22 micro-amps and
incorporates full power and signal
conditioning. The model 834M1 is available in
±2000g to ±6000g ranges and provides a flat
frequency response up to greater than 6kHz.
The standard model 834 offers the same
envelope with a lower maximum current
consumption of 4 micro-amps.
