Description

Overview of Temperature Transmitter (Two-Wire Head-Mounted)

The Temperature Transmitter is a head-mounted, two-wire transmitter designed for accurate temperature measurement in industrial processes, particularly in DCS and digital bus systems. Installed directly at the cold-end connection of a thermocouple or RTD, it outputs a standard 4–20mA linear signal proportional to the measured temperature. Capable of measuring -200℃ to 1600℃, it features compact design, low-power circuitry, and PC-programmable measuring ranges, ensuring stable, reliable operation even in harsh industrial environments.

Features of Temperature Transmitter

Two-Wire Transmission – Power supply and signal share the same pair of wires.
Standard Linear Output – 4–20mA proportional to measured temperature.
Compact Head-Mounted Design – Integrated with thermocouple or RTD for easy installation.
Wide Measuring Range – -200℃ to 1600℃, suitable for various industrial media.
PC Programmable – Measuring range can be configured to user specifications.
Low-Power, Low-Drift Circuitry – Minimizes self-heating and reduces ambient temperature influence.
Enhanced Anti-Interference Design – Ensures long-term stability and reliability.
Industrial-Grade Performance – Operates reliably in -40℃ to 80℃ environments.

Applications of Temperature Transmitter

Distributed Control Systems (DCS) and digital bus systems.
Petrochemical and oil & gas industries.
