Sensitivity is the output voltage change corresponding to a specific mechanical acceleration input. This parameter is commonly measured in mV/g, where g is the gravity of earth. Accelerometer data sheets typically report a single nominal sensitivity value. However, note that sensitivity changes with temperature, input frequency, and input acceleration level, which is why sensitivity tolerance is also stated in the sensor data sheet.
IEPE accelerometer sensitivity falls in the range of tens of mV/g to a few thousands of mV/g, with a tolerance of 5% or 10%.
The measurement range is the minimum and maximum of acceleration inputs that can be converted by the sensor to a voltage output without saturation or clipping, which is what determines the maximum output voltage (see Equation 2).
