The relatively low sensitivity improvement obtained with this preamp could be due to impedance mismatching on the input stage.
相对较低的灵敏度得到改善前置这可能是由于阻抗不匹配的输入阶段。

That the pressure signal is not linear with input voltage for pressure sensors found in experiments. The phenomenon is called electric nonlinearity for sensitivity.
实验发现压阻型压力传感器的压力输出信号与外加电压并不是线性关系，存在着灵敏度电压非线性。

In some cases, the sensitivity of the meter may be reduced, because the input stages are overloaded.
