Temperature Measurement


Infrared technology in the pulp and paper industry

October 2011 Temperature Measurement

Non-contact thermometers have a response time in milliseconds and can be used from a distance with high accuracy.

Non-contact temperature measurement devices and recovery boiler bed cameras using infrared technology are being used in pulp and paper applications around the world. Consistent monitoring of product temperature profiles is critical in continuous web and rotating equipment applications as is the monitoring of the bed level in Kraft recovery boilers. A variety of detectors with different spectral response enable users to select sensors depending on the object and application with rugged water cooled housings available for operation in ambient temperatures up to 315°C and boiler internal temperatures up to 1200°C.

Raytek infrared line scanners

Typical applications for the infrared scanner include high-speed rotating soft calendar rolls, plastic and steel extrusion machinery and slow speed rotating kilns. Infrared scanners can also be used for area inspections like monitoring temperature changes in factory areas or process bins. The heart of the Raytek system is the MP150 line scanner, which transmits the pre-processed temperature data via RS485 to a computer. Pre-processing, linearisation and calculation of the true temperature are all performed in the scanner prior to transfer.

High scan and data transmission speeds enable rapid online thermal imaging of fast moving extrusion processes. The software allows the temperature data to be visualised as a profile and a multicolour thermal image simultaneously. Temperature profiles and images can be archived for future analysis or printed for quality certification. The graphic software displays real-time profiles and thermal images of edge-to-edge product temperature, allowing machine operators to zoom into the temperature profiles to get an instant on-screen analysis. Using these graphical displays, operators can detect process temperature non-uniformities and make immediate corrective adjustments.

Enertechnix boiler bed cameras

Enertechnix’s new PyrOptix IR Cameras and high performance lenses allow complete viewing of all known critical areas in the boiler under all load conditions. Some key advantages of the solid state digital technology include providing the ability to generate clear images and to record, store and review videos if desired. The cameras also provide dual use capability to allow for fixed base applications with easy reconfiguration to a mobile device.
