This is designed to enable users to locally configure and operate the transmitter even in hazardous locations without the need for process shutdown. The Model RTT15S temperature transmitters are microprocessor controlled and use the HART version 5 or 7 communication protocols, and can receive input signals from thermocouples, resistance temperature detectors (RTDs), and ohm or millivolt sources.

Their microprocessor-based electronics minimize ambient temperature effects while delivering high accuracy, repeatability, and linearization of input signals. An advanced automatic calibration routine continuously checks zero and full-scale outputs of these transmitters against factory-calibrated voltage signals stored in non-volatile memory. The configurable backlight can be programmed to change colors or flash upon diagnostic error detection. In applications where the optional LCD display and explosion-proof housing are not required, the RTT15S is available as a basic module that can be configured remotely using PC-based device type manager (DTM) software or a handheld controller.
