1. Overview

A Universal Temperature Transmitter (UTT) is an industrial signal conditioning device designed to convert a variety of temperature sensor inputs into standardized analog or digital output signals. These transmitters are widely used in process automation and control systems to ensure accurate and reliable temperature measurement across diverse industrial environments.

2. Functional Description

The UTT accepts input from multiple temperature sensors, such as:

· RTDs (Resistance Temperature Detectors): e.g., Pt100, Pt1000

· Thermocouples (TCs): Types J, K, T, E, N, R, S, B

· Resistances and Millivolt Sources

The transmitter amplifies, linearizes, and conditions the input signal before converting it to a standardized output signal (4–20 mA or digital via HART/Modbus), compatible with PLCs, DCSs, and SCADA systems.

3. Key Features

· Universal input: Supports RTDs, TCs, resistance sensors, and voltage sources

· Standard output: 4–20 mA, HART, Modbus (optional)

· Galvanic isolation: Between input, output, and power supply

· High accuracy and stability

· Loop-powered or externally powered

· Temperature linearization and sensor fault detection

· Configuration via PC software, handheld communicator, or DIP switches

· Mounting: DIN rail or head-mounted (depending on model)
