压力传感器是一种测量元件，将一定量的压力(机械参数)转换为成比例的电输出信号(电流或电压)。该电气输出信号是压力变送器和压力开关等控制组件的技术基础。

　　原文：

　　A pressure sensor is a measuring element converting a given amount of pressure, which is a mechanical parameter, into a proportional electrical output signal (current or voltage). This electrical output signal is the technological basis for control components such as the pressure transmitter and the pressure switch.
