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.
The Rosemount 3144P temperature transmitter can be configured for a variety of sensor inputs: RTD, thermocouple, millivolt, or ohm. The HART version of the Rosemount 3144P temperature transmitter is approved for use in Safety Instrumented Systems. (Third party validated metrics are available for the 3144P. Testing done per IEC 61508 for Safety Instrumented Systems).
The Rosemount 3144P temperature transmitter's Transmitter-Sensor Matching feature eliminates interchangeability error, which improves accuracy by 75%. Sensor Drift Alert enables continuous monitoring of the differential temperature for two sensors. When one sensor drifts, the differential of the sensors will increase. If this difference exceeds defined limits, the user is alerted of an unreliable measurement. The Hot Backup feature can reduce the risk of losing important temperature measurements by 80% when the measurement automatically switches to the backup sensor if the primary sensor fails.
Meeting the NAMUR NE 21 recommendations, the Rosemount 3144P temperature transmitter ensures top transmitter performance in harsh EMC environments. In addition, the HART Rosemount 3144P temperature transmitter meets NAMUR NE 43 and NE 89 recommendations.
High performance and advanced diagnostics are available with HART or FOUNDATION fieldbus communication. Rosemount 3144P temperature transmitters offer diagnostics that provide continuous measurement status (good, bad, or uncertain), as well as sensor failure indication. Both transmitters provide performance information to AMS.
Local indication of temperature measurement and diagnosits provides immediate and accurate verification of process conditions. The Rosemount 3144P temperature transmitter is capable of single-sensor or dual-sensor input. This also allows for configuration of differential or average temperature measurements
