Optical Temperature Transmitter Has Optical Button Display
The RTT15S line of temperature transmitters has a large, backlit LCD display with optical configuration buttons operable through the glass cover of the unit’s explosionproof housing. The optical buttons allow users to locally configure and operate the transmitter even in hazardous locations without the need for process shutdown. The temperature transmitters are microprocessor controlled, 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.
