The Endress+Hauser iTHERM TR15 Modular RTD Thermometer is a robust industrial temperature measurement solution designed for demanding process applications such as steam, gas, chemical, and energy systems.

It uses a resistance temperature detector (RTD, Pt100/Pt1000) for accurate and stable temperature measurement. With its modular design and replaceable insert concept, TR15 ensures high flexibility, easy maintenance, and long service life.

The instrument is suitable for high-pressure and high-temperature environments, making it widely used in oil & gas, chemical processing, power generation, and industrial utilities.

Not Recommended For:
• Extremely fast dynamic temperature changes requiring ultra-fast response sensors
• Applications without thermowell protection in high-flow aggressive media

Technical Information TR15

Selection Notes

• Confirm the process temperature range, typically from cryogenic to high-temperature steam conditions
• Select appropriate process connection type, such as threaded, flanged, or weld-in installation
• Verify if a thermowell is required, especially for high-pressure or corrosive media
• Choose insert type, including mineral insulated (MI) or iTHERM StrongSens for enhanced stability
• Confirm hazardous area requirements, such as ATEX or IECEx approval if needed
• Define whether a head transmitter (4–20 mA / HART / Fieldbus) is required

Why Choose the TR15 Modular RTD Thermometer
