Convert a digital HART signal into three analog signals
Convert a multivariable digital HART signal into independent
4-20 mA analog process variables using the Rosemount 333
HART Tri-Loop. Apply in control or monitoring applications to
obtain up to three additional analog outputs without
additional process penetrations.
Accessory product for multivariable instruments
™
For use with the Rosemount 3051S MultiVariable
, 3051S
Advanced HART Diagnostics, and 3144P products. When
used with the 3051S MultiVariable Transmitter, the 333 HART
Tri-Loop allows possible outputs of Differential, Absolute or
Easy to configure and install
The 333 HART Tri-Loop is easy to configure and maintain
using the 475 Field Communicator. AMS
provides easy PC-based user configuration. Installation is
quick and easy with three DIN rail mount options and
electrically isolated analog output channels for flexible
grounding.
Available as either high-alarm or low-alarm device
Tri-Loop alarm channels are factory configured. All channels
alarm if the attached device indicates a sensor failure or
transmitter malfunction.
Gage pressure, Process Temperature, Mass or Volumetric
Flow, Energy Flow, Totalized Flow, and Sensor Module
Temperature. When used with the 3051S Advanced HART
Diagnostics, possible outputs include Pressure, Sensor
Module Temperature, Scaled Variable, Standard Deviation,
and Mean. When used with the Rosemount 3144P, possible
outputs include Sensor 1, Sensor 2, Differential and
Transmitter Terminal Temperature.

Failure mode alarm
If Tri-Loop diagnostics detect a Tri-Loop failure or the transmitter
indicates a transmitter malfunction, the analog signal for all
channels will be driven either below 3.75 mA or above 21.75 mA
to alert the user. The high or low alarm signal is determined by
the Tri-Loop Model Number, see
“Alarm configuration” on page 4.

Material selection
Emerson provides a variety of Rosemount products with various
product options and configurations including materials of
construction that can be expected to perform well in a wide
range of applications. The Rosemount product information
presented is intended as a guide for the purchaser to make an
appropriate selection for the application. It is the purchaser’s
sole responsibility to make a careful analysis of all process
parameters (such as all chemical components, temperature,
pressure, flow rate, abrasives, contaminants, etc.), when
specifying product materials, options, and components for the
particular application. Emerson Process Management is not in a
position to evaluate or guarantee the compatibility of the
process fluid or other process parameters with the product
options, configuration, or materials of construction selected.

Alarm configuration
Tri-Loops are configured with all channels to alarm in the same
direction. Alarm direction is configured at the factory, and
cannot be changed in the field. In addition, all channels alarm if
the attached device indicates a sensor failure or transmitter
malfunction. Tri-Loops are ordered according to the desired
alarm direction.
1. ESD tested to 8 KV air with power supply grounded.
2. Testing performed with shielded cable.

Standard configuration
Unless otherwise specified with a C2 option, Tri-Loop is shipped
as described in Table 2 .
Tri-Loop la bel
Each Tri-Loop is labeled with serial number, part number, and
factory configuration.
Custom configuration
If a Tri-Loop is ordered with a C2 option for custom
configuration, the assigned variable, variable range, variable
units, and channel status are assigned for all three channels.
333 HART Tri-Loop configuration
The 333 HART Tri-Loop can be fully configured using the 475
Field Communicator. AMS Device Manager software provides a
PC-based user configuration.
