TRZ

Introduction

This is the users’ manual for Moore Industries’ TRZ
Smart HART Temperature Transmitter.  It contains all
of the information needed to configure, install,
operate, and maintain the TRZ.  If you would like
additional assistance, call one of our STAR centers.

The following guidelines are used in this manual:

WARNING - Hazardous procedure or condition that
could injure the operator.

Caution - Hazardous procedure or condition that
could damage or destroy the unit.

Note - Information that is helpful for a procedure,
condition, or operation of the unit.

Description

The TRZ is a 2-wire (loop-powered),
user-configurable, HART

®

-based temperature

transmitter.  Typically paired with a complete
temperature assembly from our extensive line of
durable housing and enclosure options, the TRZ’s
size, accuracy, and compatibility make it the ideal
solution when temperature measurements must be
made in remote or otherwise difficult-to-access
locations.

Figure 1.  The TRZ Smart HART Temperature Transmitter’s remotely programmable input and combination analog/digital output make it the
perfect answer to problems encountered when interfacing control room equipment and field sensors.

The TRZ “reads” the signal from a RTD, Thermo-
couple,  Millivolt source,  Potentiometer, or  source
of direct resistance.  Based on this input, it transmits
both a linear, isolated 4-20mA signal 

and superim-

posed, digital HART data.  Table 1 lists the accommo-
dated input types.

The TRZ’s hybrid analog/digital signal is ideal for a
direct interface with 

both HART and non-HART read-

out instruments: recorders, DCS’s, PLC’s, and other,
computer-based SCADA equipment.
