    Reference Manual 00809-0100-4021, Rev AA Model 3144P March 2002 CONSIDERATIONS General Electrical temperature sensors, such as resistance temperature detectors (RTDs) and thermocouples (T/Cs), produce low-level signals proportional to temperature. The Model 3144P transmitter converts low-level sensor signals to a standard 4–20 mA dc signal. This current signal is then transmitted to the control room via two power/signal wires.
