The Rosemount 3144P Temperature Transmitter (available with HART or FOUNDATION fieldbus protocols) provides industry-leading accuracy, stability, and reliability. The 3144P Temperature Transmitter 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 temp transmitter 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 3144P Temp Transmitter is available with MID certification for European Custody Transfer. Contact your salesman for more information.

Features & Benefits of Rosemount 3144P Temperature Transmitter

Single-sensor and dual-sensor input capability in one transmitterEnhanced EMI rejection and filtering results in unmatched stability in process measurementSafety Certified third party validation metrics per IEC61508 for Safety Instrumented Systems (SIS)Industry-leading 5-year stability, which reduces maintenance costsHot Backup® and Sensor Drift Alert features improve measurement reliability over timeTransmitter-Sensor Matching eliminates sensor interchangeability error, which improves accuracy by 75%Dual-compartment housing provides the highest reliability in harsh environmentsIntegral LCD meter with large, easy-to-read displayThermocouple Degradation Diagnostic enables the user to monitor the resistance of their thermocouple loop to anticipate sensor failure andschedule preventative maintenance to avoid shutdownsMinimum and Maximum Temperature Tracking allows the user to monitor the temperature of Sensor 1, Sensor 2, and their differential.
