4-20mA Conversion

Yes.

with a pressure transducer that puts out a 4 - 20 ma signal and an electronic gauge that reads 4 - 20 ma signals.

Draw a linear graph between (4, low pressure of range) and (20, upper pressure of range); interpolate.

What pressure units did you want to convert the 4-20mA signal to?

Since you specify 4-20 mA I assume that you already have the pressure transducer, if so, then you need to spend about 100 dollars in one of these:

Many input types, presets, alarm capabilities and free software.

...or connect it to an analog input of some pre-existing programmable electronic system, and use the scaling function in either its hardware or its software to achieve what is desired, which hasn't been stated yet.

Some idea of to what this signal is to be connected would be rather useful.

( 20 - 4 ) = 16 steps of increments .

Starting pressure level and Max. pressure ; in Engineering unit , are to be assigned for 4 mA and 20 mA respectively .

Intermediate pressure level requires mathematical calculation - for equal distribution in range .

(P-P_L)/(P_H-P_L) = (I-4)/16.

Friend,

You can use this formule only for pressure, It doesn't work for flow
