'''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。<ref>[https://www.360kuai.com/pc/99a8e64297208c1dc?cota=3&kuai_so=1&sign=360_57c3bbd1&refer_scene=so_1 压力变送器与温度变送器的选型],【快资讯】 , 2020年4月14日</ref>
