What is it?
The Endress+Hauser iTEMP TMT82 is an advanced temperature transmitter without moving parts, designed for highly accurate and stable temperature measurement in demanding industrial environments. It is especially suited for applications in the chemical, oil & gas, and power generation industries. The transmitter features dual sensor input for redundancy or differential measurement and offers full galvanic isolation, advanced diagnostics, and HART communication for easy integration into existing automation systems.

How does it work?
The TMT82 converts signals from resistance thermometers (RTDs) or thermocouples into a standardized 4–20 mA output signal with digital HART communication. It is equipped with advanced signal processing and error detection, including sensor burnout and short-circuit monitoring. The transmitter provides galvanic isolation between input, output, and power supply to reduce electrical interference. Configuration is quick and straightforward using software tools or HART handheld devices. It also supports temperature verification and calibration documentation in compliance with international standards.

What problems does it solve?
In critical processes where precise temperature control is vital for safety and product quality, issues such as electrical noise, sensor failure, or measurement deviations can lead to serious consequences. The TMT82 offers a robust and reliable solution: its high measurement accuracy, advanced diagnostics, and fault detection enhance process reliability and help avoid costly downtime. Compliance with functional safety standards (e.g., IEC 61508) makes it suitable for SIL-rated applications. In short, the iTEMP TMT82 enables operators and engineers to manage complex temperature measurements with confidence and efficiency.
