Pyrometers for Induction Heating

Earth Tekniks Private Limited offers Pyrometers for induction heating equipment sourced from Keller HCW GmbH. CellaTemp® PQ and CellaTemp® PL Pyrometer Series were specially designed for induction heating applications. Because these instruments can measure temperatures between 0°C and 2500°C, they cover the entire temperature range of induction heating processes. Since heating is only required at selected, localised points, it is all the more important that the instrument provide a high resolution and thus precise targeting to a very small spot. Due to the pyrometers’ broadband, antireflection-coated high-precision optical system, targets with a diameter as small as Ø 0,8 mm can be achieved. For many applications, recognising the precise measurement spot can be quite helpful and is sometimes even absolutely necessary. Lasers are often used for this purpose. Their disadvantage, however, is that they only show the centre of the spot. A laser cannot indicate the true spot size or correct focus. Furthermore, the service life of lasers is limited, and they may pose a potential health hazard. The instruments of the CellaTemp PQ 28 Series have an integrated LED spot sighting system to indicate the exact target spot. With its fixed focus optics, this pyrometer is especially suitable for close-up applications between 100 to 400 mm. For its new CellaTemp PL Pyrometer Series, the company has developed an innovative optical system. This pyrometer, which also includes the integrated LED to indicate the true spot size, is distinct in that it can be focused. A sharply defined image of the spot is evidence of proper focussing. The focussing ability of the op-tics (measuring distance from 200 mm to ?) makes the CellaTemp PL extremely versatile, as it can be easily adjusted for the specific distance of the measurement task.
