Explain the difference between the transmitter and the transducer
The transducer is a device that can convert one energy to another. and a transmitter can do the same and it also can send values to your desired locations. like plc, DCS, local panel. This is not possible by the transducer.
Another difference is that we cannot change the setpoint of the transducer the transducers have fixed values as per manufacturer and the transmitter is the changeable device we change the setpoint with a multifunction calibrator as per process requirement.
A transducer sends signals in volts/millivolts/mv, and the transmitter sends signals in milliamps(MA)
