Answer to Question #125458 in Electrical Engineering for Deivasigamani

Question #125458
A piezoresistive accelerometer has the following properties and inputs:

Axial acceleration = 75 g’s

Maximum temperature effect on sensitivity = 10%

Sensitivity = 0.4 mV/g

What is the maximum reading of the axial acceleration in mV that the accelerometer may measure?

The axial acceleration is . The sensitivity is

Thus, the maximum reading of the axial acceleration in mV that the accelerometer may measure without temperature effects on sensitivity is


On the other hand, due to temperature effects the measurements can be 10% higher unless the readings are 30 mV. It means that the maximum possible reading of the axial acceleration with temperature effects on sensitivity is
