1. හැඳින්වීම
The Hart475 is an advanced hand-held interface designed for seamless communication with HART-compatible instruments. It serves as an upgraded version of the Hart375, enabling comprehensive configuration, management, maintenance, and adjustment of various field devices. This communicator allows users to monitor input/output values, review self-diagnosis results, set constant current output, and perform zero adjustments. Its plug-and-play functionality ensures ease of use during system startup or maintenance operations, requiring only a connection to the 4-20mA communication signal line. The Hart475 is fully compatible with Hart275, Hart375, and other HART475 devices, supporting communication with a wide range of instruments including 1151, 3051, EJA, ABB, and domestic intelligent pressure/temperature transmitters, as well as various flowmeters supporting the HART protocol.
