Rosemount 0444TK1U1A2NA Temperature Transmitter

The Rosemount 0444TK1U1A2NA Temperature Transmitter is a Rosemount 444 Alphaline device that translates a temperature sensor signal into a standard 4-20 mA process current for control systems. It is specified for a measurement range of 32 to 350 degrees Fahrenheit (0 to 177 degrees Celsius), enabling accurate monitoring across typical process temperatures while remaining compatible with common industrial instrumentation. The 4-20 mA output provides a proportional signal suitable for remote data transmission over standard loop wiring to PLCs, DCS, or SCADA systems, supporting reliable operation in demanding industrial environments. This model is cataloged as 0444TK1U1A2NA (sometimes listed with the CWW50 designation) and is referenced in Rosemount product literature as part of the 444 Alphaline family of temperature transmitters for process temperature measurement. Typical applications include process temperature monitoring and control in sectors such as chemical processing, oil and gas, refining, power, and pharmaceuticals, where precise, continuous temperature signals are needed to drive control loops. For installation and configuration, the exact input type, electrical ratings, and mounting options depend on the specific accessory set used with the transmitter, but the core function remains consistent: convert a temperature sensor output into a reliable 4-20 mA signal that integrates with standard instrumentation.
