Process control by the compact Optris PI 1M IR camera
In (partial) induction hardening, the #metal is #heated to the required hardening temperature and then quenched. For this purpose, an optimum temperature-time curve must be maintained to achieve the desired microstructures of the metal. If this is not done, deformation, cracking, and other deficiencies may occur. Complex geometries (e.g. gears), in particular, make uniform heating and quenching difficult. Therefore, #temperaturemonitoring of the hardening process is essential for quality assurance.
Solution from Optris by Instrotech - #Infrared #temperature monitoring
With the help of Optris infrared cameras, the temperature of the metals can be monitored during the hardening process. This type of quality assurance increases the reliability of the process. The thermal image of the infrared camera shows whether a uniform hardening (structural change) is to be expected. For this purpose, the compact and short-wave thermal imaging camera Optris PI 1M, which is particularly suitable for temperature measurements on metals, is primarily used.

Further advantages:
The compact Optris PI 05M and PI 1M infrared cameras have been specifically designed for metal industry applications. The short wavelength PI 05M is ideal for measuring molten metals in the casting process, as the new spectral range of 500 nm provides more accurate measurement with changing emissivities and is less sensitive to atmospheric influences. The Optris PI 1M is mainly used in metal processing. Here it is used e.g. for temperature monitoring during hardening, forming and welding of metals.
