Rosemount 3144P
2-8
In Conjunction with a
Rosemount 333 HART
Tri-Loop (HART / 4–20
mA only)
Use the dual-sensor option 3144P transmitter that is operating with two
sensors in conjunction with a 333 HART Tri-Loop
®
HART-to-Analog Signal
Converter to acquire an independent 4–20 mA analog output signal for each
sensor input. The 3144P transmitter can be configured to output four of the six
following digital process variables:
•Sensor 1
•Sensor 2
• Differential temperature
• Average temperature
• First good temperature,
• Transmitter terminal temperature.
The HART Tri-Loop reads 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 2-6 for basic installation information. Refer to the 333 HART
Tri-Loop HART-to-Analog Signal Converter Reference Manual (document
number 00809-0100-4754) for complete installation information.
