Endress+Hauser iTHERM SurfaceLine TM611 non-invasive thermometer

The Endress+Hauser iTHERM SurfaceLine TM611 non-invasive thermometer is designed to be used across all industries for a wide range of demanding industrial applications. The surface-mounted thermometer measures process temperature without the risk of leakage and flow disruption. A specially designed thermal coupling element is designed to provide optimal thermal conductivity to the sensor and reduce ambient influences.

Non-invasive thermometers measure the process temperature on the surface of a pipe without penetrating the pipe wall. This eliminates the risk of leakage, process contamination and flow disturbance. In addition, there is no wear on thermowells or influence from vortex-induced vibration, reducing the risk of failure and plant downtime.

The company says the iTHERM SurfaceLine TM611 features a thermal coupling element with advanced geometry specifically designed for the pipe diameter, providing a large contact surface that optimises heat transfer to the sensor. An RTD/TC sensor with low thermal mass that fits precisely into the coupling element is used, eliminating any air gaps, and a special heat transfer material applied to the coupling element compensates for any pipe imperfections.

The thermometer comes with all relevant international certifications, including explosion protection according to ATEX, IECEx, CSA and NEPSI and functional safety (SIL). In addition, it is available with the full range of Endress+Hauser iTEMP temperature transmitters, including all common analog and digital communication protocols, optional Bluetooth connectivity and diagnostics according to NAMUR NE107. The stainless steel clamps provide easy and safe installation, making it suitable for retrofitting or temporary measurements.
