Communicators | <p>HART communicators are a powerful tool for communicating with process instruments. Relying on open communications protocol, HART communicators interface with HART-enabled devices over common 4-20mA analog wiring making it much easier to configure and calibrate instruments as well as diagnose issues before they become serious. HART communicators are ideal for processes with multiple instruments that need monitoring or calibration, or when those instruments are located in hazardous locations.</p>
