what is the difference between active and passive loop

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.
