Answer Posted / vaibhav v t
HART is a protocol and not a device.It is protocol for
digital signal communnication.
HART compatible transmitter transmits digiatl signal super-
imposed on analog 4-20 mA signal and gives many useful
infoarmation about the transmitter and process parameter
other than output.
You can configure the HART based transmitter using HART
configuator withou removing the trasnmitter from its
location/process.
4-20mA is simple low current signal which is propotional to
calibration range.
