• An extensive global network of Emerson service and support personnel can be on-site when and where they are needed


Transmitter Specifications :


2-wire device with either 4–20 mA/HART, linear with temperature or input, or completely digital output with FOUNDATION fieldbus communication (ITK 5.0.1 compliant).


Input/output isolation specified to 500 Vdc (500 Vrms 707 V peak) at 50/60 Hz.

Humidity Limits

0–99% relative humidity.


ROSEMOUNT 3144P Transmitters may be attached directly to the sensor. Optional mounting brackets (codes B4 and B5) allow for remote mounting.
See “Optional Transmitter Mounting Brackets” on page 19.

Enclosure Ratings

Type 4X

IP66 and IP68

• RTDs: - ±0.1% of reading or 0.1 °C, whichever is greater, for 24 months.

• Thermocouples: - ±0.1% of reading or 0.1 °C, whichever is greater, for 12 months.

5 Year Stability
• RTDs: - ±0.25% of reading or 0.25 °C, whichever is greater, for 5 years.

• Thermocouples: - ±0.5% of reading or 0.5 °C, whichever is greater, for 5 years.

Self Calibration
The analog-to-digital measurement circuitry automatically self-calibrates for each temperature update by comparing the dynamic measurement to extremely stable and accurate internal reference elements.

Basic Information :

Adopted thermocouple temperature transmitter, thermal resistance as temperature measuring element, from  temperature measuring element output signal to a transmitter module, after filtering, arithmetic amplifier, nonlinear correction, V/I conversion, constant current and reverse protection circuit processing, convert to a linear relationship with temperature of 4 ~ 20 ma current signal 0 to 5 V / 0 to 10 V voltage signal
