Description:
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.
