压力变送器一般意义上的压力变送器主要由测压元件传感器（也称作压力传感器）、测量电路和过程连接件三部分组成。

压力变送器能将测压元件传感器感受到的气体、液体等物理压力                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               　　　　　　　变送器的传统输出直流电信号有0-5V、0-10V、1-5V、0-20mA、4-20mA等，目前最广泛采用的是用4~20mA电流来传输模拟量。

工业上最广泛采用的是用4~20mA电流来传输模拟量。
