Rosemount Model 3144 and 3244MV Smart Temperature Transmitters
2-16
INSTALLATION IN
CONJUNCTION WITH A
MODEL 333 HART
TRI-LOOP
HART-TO-ANALOG
SIGNAL CONVERTER
Use the Model 3244MV transmitter in operation with two sensors in
conjunction with a Model 333 HART Tri-Loop
®
HART-to-Analog Signal
Converter to acquire an independent 4–20 mA analog output signal for
each sensor input. During normal operation, the Model 3244MV
transmitter outputs four out of the five following digital process
variables: sensor 1, sensor 2, differential temperature, average
temperature, and transmitter terminal temperature. The HART
Tri-Loop divides the digital signal and outputs any or all of these
variables into as many as three separate 4–20 mA analog channels.
Refer to Figure 2-15 for basic installation information. Refer to the
Model 333 HART Tri-Loop HART-to-Analog Signal Converter Product
Manual (Rosemount publication number 00809-0100-4754) for
complete installation information.
