and 4wire level transmitter??and their applications also??
Answers were Sorted based on User's Feedback
In case of 4 wire transmitter, 2 wire is used to give power
and other 2 wire to transmit the signal. In case of 2 wire
transmitter, the 2 wire carries the power as well as the
signal. Example- 4to 20 mA is flowing through the 2 wire
and according to level the current is changing.

Regarding application
2 Wire transmitter is used if your cable length is small
if the length between transmitter and controller is more we
will use 4 wire transmitter.
