Rosemount 3144P Temperature Transmitter D1A1NAB4M5Q4

Rosemount 3144P Smart Family HART Temperature Transmitter (MPN: 3144PD1A1NAB4M5Q4)

The Rosemount 3144P Smart Temperature Transmitter delivers industry-leading accuracy, stability, and dual-compartment isolation for critical temperature monitoring and safety applications. Built with an engineered die-cast aluminum housing, this unit isolates the field terminal wiring compartment from the microprocessor and analog conditioning electronics. This architecture prevents moisture, sulfur-bearing gases, and ambient condensation from entering the electronics during field terminations.

Configured with factory option code D1A1NAB4M5Q4, this transmitter includes an aluminum dual-compartment field-mount housing, standard 4–20 mA/HART signal transmission, single sensor input capability, universal 316 SST 2-inch pipe/panel mounting bracket, integral 5-digit LCD display, and a factory 3-point traceable calibration certificate.

Frequently Asked Questions

What does the model code 3144PD1A1NAB4M5Q4 signify?

This specific ordering code denotes a Rosemount 3144P Smart Temperature Transmitter equipped with a dual-compartment polyurethane-painted aluminum housing (D1), 4–20 mA output with digital HART communication (A), single sensor universal input (1), standard industrial/ordinary location certification without hazardous zone ratings (NA), 316 stainless steel 2-inch pipe and panel mounting bracket (B4), integral LCD meter (M5), and a certified 3-point calibration report (Q4)

Can the Rosemount 3144P accept both RTD and Thermocouple sensors?

Yes. The 3144P is designed with a universal input card capable of processing 2-, 3-, and 4-wire RTDs (including Pt100, Pt500, Pt1000, and Cu10) as well as standard thermocouple types (B, E, J, K, N, R, S, T). Configuration between sensor types is executed entirely in software via any HART-compliant hand-held communicator or DCS configuration tool without opening the electronics compartment or changing jumpers.

Why is the dual-compartment housing superior to single-compartment designs?

The dual-compartment housing physically separates the wiring connection terminal block from the microelectronics and analog-to-digital processing engine. When technicians open the terminal cover during field commissioning or wiring checks, the sensitive electronics remain hermetically sealed and protected from humidity, rain, dust, and corrosive fumes, extending equipment life in marine and offshore settings

What is the minimum loop resistance required to communicate via HART?

A loop resistance of at least 250 ohms is required between the power supply and field communicator connection point for reliable HART communication. If your PLC or DCS input channel impedance is below 250 ohms (many are standard 100 or 150 ohms), install a series precision resistor to bring the total loop load up to the 250–1100 ohm window permitted by the supply voltage.

What is the purpose of the [TEST] terminal on the 3144P?

The [TEST] terminal enables technicians to connect a digital multimeter in series with the current loop without breaking the process loop wires or interrupting the signal sent to the DCS/PLC. Placing meter test leads across the [TEST] and [-] terminals allows direct reading of the 4–20 mA loop current via an onboard shunt diode.

Does the option NA code prevent the unit from being installed outdoors?

No. Option code “NA” simply indicates that the unit does not carry third-party hazardous area explosion-proof or intrinsically safe certifications (such as ATEX Ex d / Ex ia or FM Class 1, Div 1). The physical enclosure maintains its full environmental integrity, meeting NEMA 4X, IP66, and IP68 ratings for extreme weather, washdown, and outdoor industrial exposure.
