4-20mA calculator

A 4-20 mA signal can be used to transmit a temperature, pressure or other physical quantity. The 4-20 mA signal represents the physical quantity.

Example:
When a 4-20mA temperature transmitter has a range of 0 to 100ºC and a temperature of 20 degrees is measured, a current of 7.2 mA flows.

The quantity at a certain current can be calculated with the 4-20mA calculator below:
