Rosemount 3144p Temperature Transmitter Supplier manufacturer

Model NO.:Rosemount 3144P

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).


 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.

Reference Accuracy Example (HART only) :

When using a Pt 100 (??= 0.00385) sensor input with a 0 to 100 °C span: Digital Accuracy would be ±0.10 °C, D/A accuracy would be ±0.02% of 100 °C or ±0.02 °C, Total = ±0.12 °C.

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.

Power Supply:

External power supply required. Transmitters operate on 12.0 to 42.4 Vdc transmitter terminal voltage (with 250 ohm load, 18.1 Vdc power supply voltage is required). Transmitter power terminals rated

to 42.4 Vdc.

Basic Information :

The Rosemount 3144P Temperature Transmitter (available with HART or FOUNDATION fieldbus protocols)  provides industry-leading accuracy, stability, and reliability.The 3144P Temperature Transmitter is designed with a dual-compartment, field-mount electromechanical configuration, protecting the transmitter against water intrusion and shielding it from harmful electromagnetic surges. A 5-year stability specification and an optional integral transient protector make the 3144P the most reliable temperature measurement instrument available. The Rosemount 3144P Temperature Transmitter has the capability to accept single-sensor or dual-sensor inputs, which allows the transmitter to receive simultaneous inputs from two independent sensors. A dual-sensor configuration can be used for averaging temperatures, measuring differentials, providing a redundant temperature measurement, and taking advantage of key features, such as Hot Backup® and Sensor Drift Alert. Advanced diagnostics capabilities enable detection of sensor drift, potential thermocouple sensor or loop degradation, and enhanced insight into your processes and instrumentation. The 3144P Temp Transmitter is available with MID certification for European Custody Transfer. Contact your salesman for more information.
