Moore Industries TRX Temperature Transmitter

Name: Moore Industries TRX Temperature Transmitter – Datasheet
Brand: Moore Industries

Description

Overview

The Moore Industries TRX is a PC-programmable, non-isolated temperature transmitter built to convert direct sensor inputs into a clean, linearized 4-20 mA signal for plant control systems. As a 2-wire, loop-powered device, the Moore Industries TRX accepts inputs from 23 RTD types, 9 thermocouple types, direct millivolt sources, and resistance or potentiometer devices, giving instrumentation engineers a single transmitter platform that can be configured for almost any temperature sensing point on a process unit without stocking multiple transmitter models.

Working closely with plant engineers in the region, Seven Star LLC proudly supplies the Moore Industries TRX temperature transmitter to refineries, power plants, and process facilities across the Sultanate of Oman, Muscat, and the wider GCC region.

Operating Principle of the Moore Industries TRX

The Moore Industries TRX reads the raw signal from a connected RTD, thermocouple, resistance element or millivolt source and processes it through an internal microcontroller that applies linearization, scaling, and offset correction before delivering a proportional 4-20 mA output. Because the transmitter is fully PC-programmable using Windows-based configuration software, technicians can select the sensor type, set the measurement range, and apply custom scaling entirely from a laptop connection, without opening the transmitter housing or adjusting internal potentiometers as required by older analog trim designs.

The transmitter updates its output up to eight times per second, roughly twice the update rate of comparable microprocessor-based instruments, which keeps fast-moving temperature excursions visible to the control system without the lag that can mask transient upsets. Because the Moore Industries TRX is a non-isolated design, it is best suited to installations where galvanic isolation between the sensor circuit and the output loop is not required, letting plants specify the more cost-effective non-isolated transmitter wherever grounding conditions allow, while reserving the isolated TRY sibling for circuits with ground-loop risk.

Engineering Design of the Moore Industries TRX

Moore Industries builds the TRX around a rugged, field-proven electronics platform housed in a compact DIN-rail or head-mount enclosure, letting instrumentation teams install the transmitter directly in a sensor head, a marshalling cabinet, or a DIN-rail terminal block assembly depending on the application. The 2-wire loop-powered design means the transmitter draws its operating power from the same 4-20 mA loop it outputs to, simplifying field wiring and eliminating the need for a separate power supply run to remote sensor locations.

Configuration is handled through a PC interface cable and Moore Industries’ dedicated programming software, which stores all application-specific parameters — sensor type, range, offset, and failure mode — directly in the transmitter’s non-volatile memory. This digital configuration approach lets maintenance teams duplicate settings across multiple Moore Industries TRX units in minutes, standardizing configuration across large temperature monitoring installations while retaining the option to fine-tune individual transmitters for specific process points.

Key Features

The Moore Industries TRX temperature transmitter combines broad sensor compatibility with fast, precise signal conditioning. Core capabilities include:

Compatibility with 23 RTD types across 2-, 3-, and 4-wire configurations, covering Pt, Cu, and Ni elements from 10 to 1000 ohms.
Support for 9 thermocouple types, including J, K, E, T, R, S, B, N, and C, for wide-ranging process temperature duty.
Direct acceptance of millivolt sources from -50 to 1000 mV and resistance or potentiometer inputs up to 4000 ohms.
Fast output update rate of up to eight times per second, twice the speed of comparable microprocessor-based transmitters.
Full PC-programmability through Windows-based software for rapid, tool-free configuration in the field or bench.
2-wire, loop-powered operation that simplifies field wiring and eliminates separate power runs.
Non-isolated design optimized for cost-effective deployment where galvanic isolation is not required.
Compact DIN-rail or head-mount enclosure options suited to sensor-head and cabinet installations alike.

Industrial Applications

Process plants across the region deploy the Moore Industries TRX wherever accurate, fast-responding temperature signals feed critical control loops. Refineries and gas processing plants use it to condition RTD and thermocouple signals from reactor vessels, heat exchangers, and compressor trains, while power generation facilities rely on the TRX to monitor bearing and winding temperatures on rotating equipment. District cooling plants and desalination facilities throughout Oman use the Moore Industries TRX to standardize temperature signal conditioning across chiller plant instrumentation, and pharmaceutical and food processing sites value its PC-programmable flexibility when validating temperature loops during commissioning and requalification.

With fast quotation turnaround and technical support, Seven Star LLC distributes the Moore Industries TRX to instrumentation contractors, EPC firms, and plant maintenance departments operating within the Sohar and Salalah economic zones, as well as to industrial clients throughout Muscat and the broader Sultanate of Oman. Reliability and process control engineers can specify the Moore Industries TRX with confidence for greenfield instrumentation packages and brownfield transmitter replacement programs across the GCC.

About brand

Signal conditioning is what Moore Industries has built in North Hills, California since 1968: temperature transmitters, signal isolators, alarm trips and the interface instruments that sit between field sensors and a DCS or PLC. Seven Star LLC, an independent supplier in Oman, lists Moore Industries temperature transmitters, limit alarm trips, isolators and a PID backup controller, and sources units and replacements by full model number.

Moore Industries product families on this page

The manufacturer's catalog is arranged by function, and many of the items listed here map onto it directly:

Temperature transmitters: the TRX, and the STZ functional safety dual input smart HART transmitter
Alarm trips: the SPA2 programmable limit alarm trip, including an SPA2 with HLPRG input and four relay outputs
Signal isolators, repeaters and converters: the SIX
PID controllers and backup stations: the 535 in 1/4 DIN format

Other catalog groups include temperature assemblies and sensors, I/P and P/I converters, remote I/O, HART gateways and interfaces, indicators, and fieldbus device couplers.

Where Moore Industries instruments are used

These are control room and marshalling cabinet devices, plus field-mounted transmitters. Typical jobs are isolating a 4-20 mA loop between two systems, converting a thermocouple or RTD signal for a DCS input, adding an independent high or low trip next to the control system, and keeping a control loop running on a backup station when the main controller is out of service. Process plants in oil and gas, chemicals and power across the GCC use them for exactly these tasks.

Ordering Moore Industries instruments: what we need

Moore Industries model numbers are built from fields separated by slashes: unit, input, output, power and options, followed by the housing code in brackets. Every field matters. Send the complete string from the label, the serial number, and for programmable units the input type and range you want set. State any hazardous area or functional safety requirement, because approved versions are ordered with their own option codes.
