When it comes to demanding industrial environments, accurate and safe temperature measurement is essential. Enter the iTHERM SurfaceLine TM611, a cutting-edge, non-invasive thermometer from Endress+Hauser, supplied by us at EMC Industrial Group, redefining what’s possible in temperature monitoring. Designed for reliability and performance across all industries, the TM611 provides a breakthrough solution for harsh process conditions where traditional invasive methods fall short.

A Safer, Smarter Alternative

The iTHERM SurfaceLine TM611 is a surface-mounted thermometer that delivers precise temperature measurements without the need to penetrate the process medium. This means no risk of leakage, contamination, or process interruption, making it an ideal choice for safety-critical applications.

Unlike conventional invasive thermometers, which require physical access to the medium through process openings, the TM611 measures temperature externally, on the pipe surface, using a specially engineered thermal coupling element. This design ensures optimal thermal conductivity, minimises ambient influences, and delivers measurement accuracy that matches or even exceeds that of invasive sensors.

Unmatched Accuracy and Response Time

One of the TM611’s most impressive achievements is its superior accuracy and fast response time. Through extensive development and rigorous field testing, Endress+Hauser has fine-tuned the device to overcome the traditional limitations of surface measurement.

In real-world tests, the TM611’s performance mirrored that of invasive measurement systems, even demonstrating faster response times in certain scenarios. This high fidelity enables operators to trust the data, even in dynamic process conditions.

Enhanced Safety for People, Plants, and Processes

By completely eliminating the need to breach the pipe wall, the TM611 dramatically improves plant safety. There is no wear on thermowells, no exposure to vortex-induced vibrations, and no risk of process fluid escape — all of which reduce the likelihood of system failure, unplanned downtime, or hazardous incidents.

With its robust design and advanced thermal technology, the TM611 ensures safe operation while maintaining exceptional measurement performance.

Substantial Time and Cost Savings

The TM611 delivers more than just technical excellence, it also offers tangible cost and time savings throughout the entire project lifecycle:

  • Simplified engineering: No need for complex calculations related to wake frequency or insertion depth.
  • Lower material costs: Eliminates components like thermowells, nozzles, and flanges.
  • Streamlined installation: Requires no welding, seam tests, or special certifications.
  • Reduced maintenance: No regular inspections or replacements due to wear and tear.

All these factors contribute to a lower total cost of ownership and faster deployment, especially for retrofitting or temporary measurement scenarios.

Universal Application Across Industries

The iTHERM SurfaceLine TM611 is versatile and universally applicable, making it suitable for a broad range of industries and environments. It excels in challenging conditions involving:

  • High flow velocities and pressures
  • Viscous, abrasive, or corrosive media
  • Small pipe diameters or piggable systems

Whether you’re launching a greenfield project, upgrading an existing facility, or conducting temporary or mobile measurements, the TM611 offers the flexibility and precision needed to get the job done safely and efficiently.

Engineered for Excellence

Every aspect of the TM611, from material selection to geometry and surface finish, is carefully optimised for uniform heat transfer. Comprehensive thermal analysis and minimised heat transfer resistance make this device a benchmark for non-invasive temperature measurement.
