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.
Features & Benefits：
· Single-sensor and dual-sensor inputcapability in one transmitter
· Enhanced EMI rejection and filtering results inunmatched stabilityin process measurement
· Safety Certified third party validation metrics per IEC61508 forSafety Instrumented Systems (SIS)
· Industry-leading5-year stability, which reduces maintenance costs
·Hot Backup®andSensor Drift Alertfeatures improve measurement reliability over time
·Transmitter-Sensor Matchingeliminates sensor interchangeability error, which improves accuracy by 75%
·Dual-compartment housingprovides the highest reliability in harsh environments
· Integral LCD meter with large, easy-to-read display
· Thermocouple Degradation Diagnostic enables the user to monitor the resistance of their thermocouple loop to anticipate sensor failure and schedule preventative maintenance to avoid shutdowns
· Minimum and Maximum Temperature Tracking allows the user to monitor the temperature of Sensor 1, Sensor 2, and their differential.
