This pressure transmitter 4 to 20 milliamp current output calculator provides a way to determine the output reading from the applied pressure and pressure transmitter range. A conversion scale graphic for each pressure and 4-20mA current output range combination entered is also displayed below the calculated values.
This pressure transmitter output calculator uses the following formula to calculate the output over a 4-20mA range:
Linear mA out = 4 + (16 x ((Rdg – Low Limit) / (High Limit – Low Limit)))
Enter the unit used for measuring pressure, e.g. bar, psi, kPa, inH2O etc…
This is the applied pressure measured by the pressure transmitter that you wish to convert to a 4 to 20 milliamp current output reading.
Enter the lowest pressure that the pressure transmitter will measure. For example zero would be a typical value for most pressure transmitters, but you can also add negative (-) or positive (+) values as well. Please enter the value in the same pressure units as specified for all other input values.
Enter the maximum pressure that the pressure transmitter will measure.
Output Reading (mA)
This is the expected ideal pressure transmitter current output signal in milliamps for the applied pressure specified.
