Temperature transmitters are essential for reliable and accurate insight into your process. Rosemount single point temperature transmitters have defined the standard for innovation and dependability for the process industry. Emerson provides transmitter solutions to meet a variety of application needs across your plant.
The Rosemount 3144P Temperature Transmitter (available with HART or FOUNDATION fieldbus protocols) provides industry-leading accuracy, stability, and reliability. The 3144P is designed with a dual-compartment, field-mount electromechanical configuration, protecting the transmitter against water intrusion and shielding it from harmful electromagnetic surges. A 5-year stability specification and an optional integral transient protector make the 3144P the most reliable temperature measurement instrument available. The Rosemount 3144P has the capability to accept single-sensor or dual-sensor inputs, which allows the transmitter to receive simultaneous inputs from two independent sensors. A dual-sensor configuration can be used for averaging temperatures, measuring differentials, providing a redundant temperature measurement, and taking advantage of key features, such as Hot Backup® and Sensor Drift Alert. Advanced diagnostics capabilities enable detection of sensor drift, potential thermocouple sensor or loop degradation, and enhanced insight into your processes and instrumentation.
The industry-leading Rosemount 648 Wireless Temperature Transmitter delivers unmatched field reliability and performance as a wireless measurement solution. The 648 Wireless is ideal for high performance applications, helping you achieve optimal efficiency with Best-in-Class product specifications and capabilities.
