Answer / mathan.j

24v is a supply source for tx. if it is a pressure tx, a
diapharm placed inside the tx. it will sense the pressure.
depending upon the pressure level ,the diapharm moved
between top to bottom & a position feedback signal is
generated depends upon the diapharm level,this signal is 4-
20 ma.

Answer / nitin ku.sharma

in case of Siemens level transmitter we give 220V AC,so it is not necessarily that we give 24V as input.as in case of 24V input supply we kept a constant resistance of fixed value and since V is fixed and R will increase than I will decrease and vice versa.we get 4 ma when resistance is min. and 20 ma when resistance is max.
