Emerson 444TE1U1A1NA Temperature Transmitter

Emerson's Rosemount 444TE1U1A1NA Alphaline Temperature Transmitter converts a thermocouple input to a 4-20 mA process signal, enabling precise temperature monitoring in industrial control loops. The 444TE1U1A1NA belongs to the Rosemount 444 Alphaline family and, as part of the 444T series, supports thermocouple inputs (the TE suffix indicates Type E thermocouple) and other configurations (TE, TJ, TK, TT, TR, TS), providing robust, calibrated temperature measurement from remote sensing points. It includes the characteristic open-input protection seen in 444T devices, where the output can be driven upscale or downscale if the input circuit opens, helping signal faults safely in a process. The listed specification shows a measurement range of 100–300 °C for this model configuration.
