How to do 4-20mA Conversions Easily

Generally it is possible to generate a “custom” linear equation in the form of y = mx + b for any linear

Example of 3-15 psi to 4-20mA Conversion

A current-to-pressure transducer is  used  to  convert  a  4-20 mA  electronic  signal  into  a  3-15 PSI pneumatic signal. This particular

4-20mA Formulas and Examples

4-20 mA transmitter current output can be converted to the voltage within a specified range, from 0 to a maximal amplitude Vmax,

4-20mA Graphical Calculations

An illustration sometimes find helpful in understanding analog signal ranges is to consider the signal range as a length expressed on

Formula to Calculate 3-15psi from 4-20mA Current

The amount of psi can also be calculated from the amount of the milliamp signal, or one can calculate the amount of the milliamp

Calculate Process Variable from Transmitter Current
