The 577506 RTD Temperature Transmitter is designed for close-coupled, integrally-mounted applications. Using microcontroller-based circuitry, the 577506 senses resistance changes as a function of temperature and provides an extremely stable and accurate 4 to 20mA DC loop output. Field rangeability and user selectable features allow a single device to satisfy virtually all temperature applications. Re-calibration or programming is done in seconds using standard hand tools. No soldering or component changes are necessary. The transmitter is housed in a gasketed, explosion-proof enclosure. The enclosure is CSA and UL approved for Class I, Groups C& D, Class II, Groups E, F, & G, and Class III locations.
