How Do I Choose The Sensitivity of an Accelerometer?

From Honeywell Sensing and Control / Sensors for Test & Measurement
 

 

Accelerometers with integral electronics have a maximum output voltage determined by the circuit design and the input voltage. The maximum output for an IEPE accelerometer is typically 4-8 volts. An accelerometer with a sensitivity of 100mV/g with electronics that has a maximum output of 5V will obviously have a dynamic range of +/- 50g while an accelerometer of sensitivity of 10mV/g will have a dynamic range of +/- 500g If the maximum g levels likely to be experienced is known then dividing this number by 5 volts will give the maximum sensitivity that should be used to get this dynamic range
