the linear variable differential transmitter or transformer has a potentiometer(varrying resistance) when it stretched the resistance changes. With the 24vdc supply, the ohms law is completed to give a linear 4-20mA output to your controller or indicator. same storry applies on the RVDT

if we open the inlet of an air regulator ,how it will affect the out put of regulator? (out put of regulator is using to operate an on-off valve.it is an air to open valve,and valve is in open position.my doubt is air regulator will hold the valve in open or not,if there is no consumption or leak in regulator out put side ,we only loose the input pressure.)
