Temperature Measurement Solutions Providing Increased Efficiency e.g. for Hardening Processes The ISR 6-TI Advanced infrared thermometer by LumaSense combines accurate (2-color) pyrometry and thermal imaging in one non-contact temperature measurement system. his hybrid pyrometer solution by LumaSense Technologies is a major breakthrough combining an infrared thermometer with thermal imaging capabilities to open new sensing opportunities for heat-dependent manufacturers and various industrial applications. T Particularly in the steel and metal processing industry, the use of non-contact temperature measurement has become essential for monitoring and controlling production processes. One example is induction hardening and tempering, where a particular spot of the workpiece (such as precision parts made of steel or cast steel) is heated up and subsequently quenched rapidly. For such contactless heating methods, usually only a special area on the surface of the workpiece is selectively heated. This method of selectively heating and quenching a workpiece is critical in achieving the desired hardness of the material. If the temperature is too low, it will lead to insufficient surface hardness. However, if the temperature is too high, it may damage the workpiece so it becomes unusable. For measurement tasks with high reproducibility (as required in hardening processes), LumaSense offers IMPAC Series 6 Advanced pyrometers, which are available in different wavelength ranges and cover temperatures from 50 °C to 3000 °C, depending on model and application. 10 PECM Issue 17 IMPAC ISR 6-TI Advanced It is a novel solution to combine accurate twocolor pyrometer measurement (from 700 °C to 1800°C) with thermal imaging display capability. As the latest special in this Series and in order to detect and monitor the temperature distribution on the workpiece, the IMPAC ISR 6-TI Advanced comes into play. It is a novel solution to combine accurate two-color pyrometer measurement (from 700 °C to 1800°C) with thermal imaging display capability. This allows a specific indication of the temperature distribution of a dedicated region on the objects surface. The ROI functionality contained in the supplied InfraWin software enables the definition and evaluation of specific “regions of interest”. When combined with an optional I/O module, it is e.g. possible to trigger external (switching-) contacts based on the temperature data of one or more ROI’s. More information: www.lumasenseinc.com
