Temperature transmitters with optical configuration buttons
These Foxboro RTT15S Optical Temperature Transmitters from Schneider Electric are a new family of temperature transmitters that features a large, backlit LCD display. The optical configuration buttons are operable through the glass cover of the unit’s explosion-proof housing to enable users to locally configure and operate the transmitter even in hazardous locations without the need for process shutdown. Designed to serve a wide range of temperature applications, the transmitters are microprocessor controlled, use 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.
