位移变送器又名行程发讯器,它是把直线移动的机械量变化变换成电量的变化,适用于测量伸长、膨胀、应变、压力、重量等,是工农业生产、国防工程及科学研究中测量静态位移及动态位移过程的传感器,可广泛地应用在自动测量及自动控制中。构成位移变送器的方法很多,有差动变压器式,电感式,电容式,应变电阻式,压磁式,弦式等等。 Also known as displacement transmitter displacement transmitter, it is the linear movement of the mechanical changes change into electricity changes, suitable for measuring elongation, expansion, strain, pressure, weight, etc., is the industrial and agricultural production, national defense engineering and science The sensors that measure static displacement and dynamic displacement in the study can be widely used in automatic measurement and automatic control. There are many ways to constitute the displacement transmitter, a differential transformer, inductive, capacitive, strain resistance, pressure magnetic, string type and so on.
