HART : Highway Addressable Remote Transducer

This is a communication protocol in which all information related to transmitter / instrument travels in the same pair of power loop of transmitter.

This information is transmitted by superimposing HART signal (AC) on 4-20mA DC signal. Hence HART DC value remains zero and it will not impact 4-20mA measurement.

The digital HART information is transmitted by two different signal 1200 Hz (Represented as 1) and 2200 Hz(Represents 0) in digital system.

Since transmitter are Highway Addressable, it is possible to configure transmitter remotely through a management system (e.g. AMS or PRM).

Hope this will help.

Hart stands for Highway addressable remote transmitter.
signals are in form of mA (4-20) current loop
so that it is not effected by wire resistance.
but it is slow with respect to other types like fieldbus ff ,profibus and modbus.
