The non-invasive thermometer iTHERM SurfaceLine TM611 by Endress+Hauser provides accuracy and response time comparable to invasive temperature measurement.
The iTHERM-SurfaceLine-TM611 from Endress+Hauser is ideal for demanding process conditions.
The iTHERM SurfaceLine TM611 can be used across all industries for a range of demanding applications. The surface-mounted thermometer measures process temperature without the risk of leakage and flow disruption. A specially designed thermal coupling element provides ideal thermal conductivity to the sensor and reduces ambient influences, providing optimum measurement performance.
The instrument offers increased safety for personnel, plant. and the environment. 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.
In its design the Endress+Hauser surface thermometer iTHERM SurfaceLine TM611 redefines non-invasive temperature measurement. It 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. This advantage is enhanced by an RTD/TC sensor with low thermal mass that fits precisely into the coupling element, eliminating any air gaps. A special heat transfer material applied to the coupling element compensates for any pipe imperfections. This product design results in accurate measurements without the need for error-prone electronic compensation, calculations or algorithms.
The device also offers significant cost and time savings. In contrast to traditional invasive temperature measurement methods, non-invasive thermometers offer significant savings at various steps – from project engineering to procurement, installation and operation. Development and design times are markedly reduced by eliminating the need for wake frequency and insertion depth calculations. Installation becomes more economical with reduced material expenses for thermowells, nozzles, pipe extensions and flanges. This cost efficiency also extends to services such as weld seam tests and material certification. Non-invasive thermometers also minimise lifecycle costs by eliminating risks such as thermowell breakage, leakage and regular inspection.
Designed to meet wide-ranging requirements
The product is equipped with all relevant international certifications, including explosion protection according to ATEX, IECEx, CSA and NEPSI and functional safety (SIL). In addition, iTHERM SurfaceLine TM611 is available with the full range of Endress+Hauser iTEMP temperature transmitters, including all common analogue and digital communication protocols, optional Bluetooth® connectivity and advanced diagnostics according to NAMUR NE107. The stainless steel clamps provide for easy and safe installation, making the instrument suitable for retrofitting or temporary measurements.
These features establish the non-invasive thermometer as the perfect solution for energy and safety monitoring, as well as for demanding applications, such as high flow velocities or process pressures, highly viscous or corrosive media and applications including pigging or small pipe diameters.
