变送器是从传感器发展而来的，凡是能输出标准信号的传感器。标准信号是指物理量的形式和数量范围都符合国际标准的信号。由于直流信号具有不受线路中电感、电容及负载性质的影响，不存在相移问题等优点，所以国际电工委员会(IEC)将电流信号 4mA~20mA(DC)和电压信号 1V~5V(DC)确定为过程控制系统中模拟信号的统一标准。变送器是基于负反馈原理工作的，它主要由测量部分、放大器和反馈部分组成。测量部分用于检测被测变量x，并将其转换成能被放大器接受的输入信号Zi(电压、电流、位移、作用力或力矩等信号)。反馈部分则把变送器的输出信号y转换成反馈信号Zf，再回送至输入端。Zi与调零信号Zo的代数和同反馈信号Zf进行比较，其差值ε送入放大器进行放大，并转换成标准输出信号y。
