Non-invasive thermometer delivers fast, invasive-level accuracy
iTherm SurfaceLine TM611 non-invasive thermometer is designed for demanding process conditions, such as high flow velocities, elevated pressures, corrosive or abrasive media and small pipe diameters. Unlike conventional invasive sensors that require thermowells, flanges or pipe modifications, it mounts externally on the pipe surface. Its advanced, thermal-coupling element ensures optimal heat transfer to the sensor, while minimizing ambient interference. This design enables measurement accuracy and response time comparable to invasive RTD and thermocouple sensors without the risking leaks or process disruptions.
iTherm SurfaceLine TM611yechnical highlights include:
- Wide temperature range
- Accuracy classes, including Class AA, A, B (IEC 60751), Class 1 or 2 (IEC 60584-2), and ASTM E230 standards
- Response time comparable or superior to invasive sensors, even at shallow immersion depths
- RTD or thermocouple sensor types
- iTemp transmitter with support for major communication protocols and optional Bluetooth connectivity
- Certifications, including ATEX, IECEx, CSA, NEPSI for explosion protection; SIL for functional safety
In addition, iTherm SurfaceLine TM611’s modular design supports flexible positioning on various pipe sizes and configurations, enabling installation across multiple points without interrupting operations. It’s especially effective in applications involving pigging, abrasion or highly viscous media, where invasive sensors may be impractical or unsafe.
