Answer / nitin patil

i am giving here the formula for the same,
temp/ pressure = (ma - 4)* span / 16


where, ma = what you measured by multimeter
span = max range of the transmitter.

Answer / arun raja.s

Eg. you want to convert in DCS mean it for pressure
transmitter

field pressure Range : 0-100 Bar

Transmitter Calibration Range : 0-100 Bar so output 4-20
mA Depent on the Transmitter input pressure.

This output cable goto Analog input module, in DCS have
to set 0-100 Bar it work depent on 4-20 mA input.

Answer / mastersensor80

the sensor in the transmitter sense the physical effect
(pressure/level/flow) in the transducer this effect is
converted to electrical effect where we can measure 4 -20
ma for example that on the transeducer and the sensor
part,but to answer the above question it is mainly as
answered by Nitin Patil it is merly calculation as the
forumla provided by Nitin.

Answer / neeraj pundir

with the help of transducer we convert (temp,pressure) in
outputs milliamps signals.

Answer / mohanraj k

Milliamps output can be converted to temperature or
pressure, by means of converting the amps to volt by placing
a 250ohm resister across the circuit.

Why 4-20mA SIGNAL IS PREFERRED OVEA A 0-10v signal?
