Rosemount 3144P Temperature Transmitter
The Rosemount 3144P Temperature Transmitter is the industry leader when it comes to transmitting temperatures used in critical control and safety applications. With the capability to accept either single-sensor or dual-sensor inputs, it performs with top-of-the-line accuracy, stability, and reliability. The dual sensor input function affords the Rosemount 3144P Temperature Transmitter the ability to accept simultaneous input from two independent sensors, enabling measurement of differential temperatures, averaging temperature or redundant temperature. Local indication of temperature measurement and diagnostics provides immediate and accurate verification of process conditions.
The Rosemount 3144P Temperature Transmitter is available with either 4-20 mA/HART or a completely digital FOUNDATION fieldbus protocol. It can also be configured for a variety of sensor inputs including:
To improve measurement accuracy by 75%, the transmitter-sensor matching feature eliminates interchangeability error, while the sensor drift alert continuously monitors the differential temperature for two sensors. If one sensor drifts, causing the differential of the sensors to increase to a level that exceeds defined limits, the user is alerted of an unreliable measurement. In the event of a primary sensor failure, The Rosemount 3144P Temperature Transmitter’s hot backup feature automatically switches the measurement to the backup sensor, reducing the risk of losing important temperature measurements by 80%.
The Rosemount 3144P Temperature Transmitter ensures top transmitter performance in harsh EMC environments and meets NAMUR NE 21 recommendations.
The HART Rosemount 3144P Temperature Transmitter meets NAMUR NE 43 and NE 89 recommendations and 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).
Rosemount 3144P Temperature Transmitters indicate sensor failure and offer diagnostics that provide continuous measurement status (good, bad, or uncertain). High performance and advanced diagnostics are available with HART or FOUNDATION fieldbus communication. Both transmitters provide performance information to AMS.
