What is the differences of Level swich( LS ) and Level Transmitter(LT)

Question Posted / er. anish raj

Answer Posted / er. anish raj

Level Switch performs only switching mechanism. ie. when its electronic circuitry senses the present level is the desired one then its relay coil will operate & the NO contact will turn into NC and vice versa.
Whereas the Level Transmitter will visualize the signal, perform signal conditioning ( amplification) and then transmit the current signal to the controller in the form of 4-20 mA.

Thanks.
