User Guide
This temperature transmitter 4 to 20 milliamp current output calculator provides a way to determine the output reading from the applied temperature and temperature transmitter range. A conversion scale graphic for each temperature and 4-20mA current output range combination entered is also displayed below the calculated values.
Formula
This temperature 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)))
Parameters
Unit
Enter the unit used for measuring temperature, e.g. °C, °F, degC, degF, etc…
Reading
This is the applied temperature measured by the temperature transmitter that you wish to convert to a 4 to 20 milliamp current output reading.
Low Limit
Enter the lowest temperature that the temperature transmitter will measure. You can enter negative (-) or positive (+) values. Please enter the value in the same temperature units as specified for all other input values.
High Limit
Enter the maximum temperature that the temperature transmitter will measure.
Output Reading (mA)
This is the expected ideal temperature transmitter current output signal in milliamps for the applied temperature specified.
