HART® or Highway Addressable Remote Transducer is a type of digital communications protocol for configuring and reading instrumentation via the 4 to 20mA current loop. HART® data is communicated via a low level AC digital signal which is superimposed on a 2 wire 4-20mA current loop signal and functions simultaneously without interfering with the measurement output signal.
