    Rosemount Model 3144 and 3244MV Smart Temperature Transmitters COMMISSIONING: ON THE The transmitter may be commissioned before or after installation. However, it may be useful to commission the transmitter on the bench BENCH OR IN THE LOOP before installation to ensure proper operation and to familiarize yourself with its functionality.

  • Page 11: General Considerations

    (RTDs) and thermocouples (T/Cs) produce low-level signals CONSIDERATIONS proportional to temperature. The Model 3144 and 3244MV transmitters convert low-level sensor signals to a standard 4–20 mA dc signal that is relatively insensitive to lead length and electrical noise. This current signal is then transmitted to the control room via two wires.

  • Page 12: Field Wiring

    Rosemount Model 3144 and 3244MV Smart Temperature Transmitters Field Wiring All power to the transmitter is supplied over the signal wiring. Signal wiring does not need to be shielded, but twisted pairs should be used for the best results. Do not run unshielded signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment.

  • Page 13: Grounding

    Installation NOTE Do not connect the power/signal wiring to the test terminals. The voltage present on the power/signal leads may burn out the reverse-polarity protection diode that is built in to the test terminal. If the test terminals’ reverse polarity protection diode is burned out by the power/signal wiring, the transmitter can still be operated by jumping the current from one test terminal to the other.
