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:






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
HART-to-Analog Signal Converter Reference Manual (document number 00809-0100-4754) for
complete installation information.
