The THZ2 and TDZ2 family of two-wire, loop-powered smart HART temperature and signal transmitters have input-to-output analog accuracy up to ±0.014°C (±0.025°F). The 4-20mA temperature output signal also has a superimposed HART digital signal, which allows any HART-compatible control device to program zero, span, sensor trim offset and other calibration variables, and to interrogate and read multiple real-time process variables. Up to 15 transmitters can be linked via a single twisted pair wire. The THZ2 and TDZ2 can be field-configured to accept 14 RTD types, nine thermocouple types, current and voltage signals, resistance and potentiometer devices, and direct millivolt sources, thus minimizing the need to stock spares. Both the THZ2 models (blind devices) and TDZ2 (with displays) have 20-bit input resolution for exceptional digital accuracy of ±0.1C (±0.18F) with all Pt RTDs, or up to ±0.05C (±0.09F) for Pt1000 RTDs.
