HART communication protocol is a communication protocol used between field smart meters and control room equipment. HART communication device provides communication with relatively low bandwidth, moderate response time, after more than 10 years of development, HART technology has been very mature abroad, and has become the global industry standard of intelligent meters.

The HART communication protocol of the pressure transmitter provides two synchronous communication channels: 4~20mA analog signal and one digital signal. The 4~20mA signal uses a 4~20mA current loop to transmit the main measured value.

In addition, HART communication uses digital signals superimposed on the analog signal of the pressure transmitter to transmit information about other equipment of the pressure transmitter. The digital signal of the pressure transmitter contains information from the device, including equipment status, diagnostics, additional measured or calculated values, etc. Pressure transmitters These two communication channels combine to provide a low-cost, highly reliable, complete pressure transmitter field communication solution that is easy to use and configure.

There are many ways to communicate pressure transmitters, and intelligent pressure transmitters using the HART communication protocol are widely used in various industrial fields. Suitable for pressure measurement in the liquid or gas and process industries.
