Answer Posted / rahul sr
Passive Loop: The transducer must be provided by an
external power supply for its working. Then it generates
the signal according to the Process parameter. This may
have either 2 wires, 3 wires or 4 wires.
Active Loop: There is no need to give external power supply
for the transducer. The sensor itself generates signal
without giving power supply. This will have only 2 wires.
