Rosemount 3144P Temperature Transmitter

The Rosemount 3144P temperature transmitter provides superior accuracy, stability, and reliability – making it the industry-leading temperature transmitter used in critical control and safety applications. The Rosemount 3144P temperature transmitter is available with either 4-20 mA/HART or a completely digital FOUNDATION fieldbus protocol. It has the capability to accept either single-sensor or dual-sensor inputs. This dual sensor input capability allows the transmitter to accept simultaneous input from two independent sensors, enabling measurement of differential temperatures, averaging temperature or redundant temperature measurement.

Rosemount 644 Temperature Transmitter

The Rosemount 644 temperature transmitter is designed for use in control applications where the loss of the temperature points may be detrimental. These highly accurate Rosemount 644 temperature transmitters are available in a variety of mounting styles, field housings, and communication protocols to meet your demanding installation requirements.
