Rosemount 3144P Temperature Transmitter
with HART® Protocol
The Rosemount 3144P Temperature
Transmitter with HART protocol provides superior accuracy, stability, and
reliability, making it the industry-leading temperature transmitters used
in Control & Safety applications. The Rosemount 3144P has capabilities for
either a single-sensor or dual-sensor input. This dual-sensor input capability allows
the transmitter to accept simultaneous input from two independent sensors.
This dual-sensor configuration can be used for measuring differential temperatures,
averaging temperature or redundant temperature measurement.
The ultimate temperature transmitter for Control & Safety
applications
Single-sensor and dual-sensor capability in one transmitter
Enhanced EMI rejection and filtering results in unmatched stability in
process measurement
Third party validation metrics per IEC61508
for Safety Instrumented Systems (SIS)
Industry leading 5 year stability, which reduces maintenance costs
Hot Backup® and Sensor Drift
Alert features improve measurement reliability over time
Dual-compartment housing that provides the highest reliability in
harsh environments
Integral LCD meter with large, easy to read display
