The Murphy 0-400F Resistance Temperature Detector Transmitter Assembly RTDT-225-400-100 features a 304 stainless steel thermowell that provides protection to the spring loaded element. The cast aluminum connecting head meets NEMA 4 requirements and includes an RTD transmitter. This model is available as part of the temperature sensor assemblies or as a separate units, the RTDT’s accept 2 or 3 wire, 100 ohm RTD’s. The RTD transmitters are loop powered, they feature linearized 4-20 mA DC outputs and have reversed polarity protection.

Applications: Enovation Control’s temperature sensing assemblies fit in a variety of industrial processes and applications. Their ruggedness and characteristics make these assemblies a popular and price-competitive choice.
