Emerson Electric Co. 3044C A1E5B4 Temperature Transmitter

Rosemount 3044C A1E5B4 Temperature Transmitter from Emerson converts a temperature sensor signal into a 4-20 mA current loop for remote monitoring and control. It operates on a 12.5–55 VDC supply and provides a measurement range of 0–150 °C, enabling direct representation of process temperature in standard industrial loops. The A1E5B4 suffix identifies a specific configuration within the Rosemount 3044C family, ensuring consistent factory settings for compatibility with common 4-20 mA instrumentation and control networks. This transmitter is designed for use in challenging plant environments and supports straightforward connection to control systems via the conventional 4-20 mA interface, making it suitable for integration with PLCs and DCSs. In practice, you would install a temperature sensor appropriate to your process, connect it to the 3044C, and monitor the transmitter output on your 4-20 mA input, using the reading to control setpoints, alarms, and trending. When selecting this model, confirm that your supply stays within 12.5–55 VDC and that your desired measurement range includes 0–150 °C, as these are the documented specifications for this variant. As part of the Rosemount family, the 3044C A1E5B4 reflects Emerson’s approach to reliable, repeatable temperature measurement in industrial environments, offering a standard, widely supported transmitter option when a 4-20 mA temperature signal is required.
