Rosemount 3144P Temperature Transmitter
The ultimate temperature transmitter for any Single Point measurement application.
The Rosemount 3144P Temperature Transmitter with HART or FOUNDATION fieldbus protocols provides industry-leading accuracy, stability, and reliability. Designed with a dual-compartment field-mount electromechanical configuration, a 5 year stability specification and an optional integral transient protector, the 3144P is the most reliable temperature measurement instrument available. The Rosemount 3144P has capabilities for either a single-sensor or dual-sensor inputs which allows the transmitter to accept simultaneous input from two independent sensors. This dual-sensor configuration can be used for measuring differential temperatures, averaging temperature or redundant temperature measurement. The 3144P’s advanced diagnostics capabilities enable detection of sensor drift, potential thermocouple loop degradation, and enhanced insight into your processes and instrumentation.
