Calibrating a HART temperature transmitter requires an accurate temperature simulator or temperature source, mA measurement, and a HART communication tool for calibration. You can use separate tools or a calibrator that integrates all three to perform this task. HART is an industry standard defining the communications protocol between smart field devices and a control system that uses 4-20 mA wiring. Before going to the field, gather the needed calibration and communication test tools. If testing...
