In many industries the use of non-contact temperature measurement has become essential for monitoring and controlling production processes. This is particularly the case where high quality standards can only be guaranteed by precisely controlling temperature for even the smallest components.

During induction hardening and tempering, 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 specific area on the surface of the workpiece is selectively heated.

This method of selectively heating and quenching a workpiece is critical in achieving the required hardness of the material. If the temperature is too low, it will lead to insufficient surface hardness; if the temperature is too high, it may damage the workpiece so that it becomes unusable. By adjusting the induction coil, pieces in various shapes can be heated up correctly for the hardening process.

For efficient process monitoring and control through temperature measurement, LumaSense Technologies offers a range of infrared pyrometers. These instruments are suitable for different industrial applications and can be configured for accurate measurements, even in the harshest working environments. The portfolio includes standard pyrometers and two-colour pyrometers as well as composite solutions, which consist of pyrometers with integrated thermal imaging functionality.

For measurement tasks with high reproducibility (as required in hardening processes), LumaSense offers its Series 6 advanced pyrometers, which are available in different wavelength ranges and cover temperatures from 50 °C to 3 000 °C. The series includes, for example, the IMPAC ISR 6 and the IGAR 6 Advanced pyrometers, which cover a wide range of metal processing applications.

Mecosa (Pty) Ltd is the sole agent for LumaSense Technologies GmbH in Southern Africa.

Crown Publications, one of South Africa’s largest business-to-business publishing houses, came into existence in 1986. Since then, the company has grown from producing a single magazine, Electricity SA (renamed Electricity+Control), to publishing six monthly magazines, three quarterlies, and a number of engineering handbooks.
