Short wavelength infrared temperature sensors provide improved results on hot metal surfaces. Here is a comparison of three of our shortwave pyrometers.

Calex short wavelength (2.0 to 2.6 µm) infrared temperature sensors are suitable for accurately measuring the surface temperature of non-metals and some metals at high or low temperatures. These sensors have adjustable emissivity settings, reflected energy compensation and peak and valley hold processing, making them particularly suitable for measuring hot objects in a furnace or on … Continue reading Comparison of Short Wavelength Infrared Temperature Sensors

Calex normally recommends using a short-wavelength infrared temperature sensor to measure the temperature of metals, instead of a general-purpose type, because it is more accurate. But why is it more accurate? Here are the reasons. 

Calex has achieved success in measuring the surface temperature of extruded aluminium profiles using low-cost non-contact pyrometers. Measurements were taken by a leading manufacturer of extruded profiles at the press exit and after the quench, and good results were obtained with short-wavelength single-wavelength pyrometers, even with significant steam near the quench box.

The FibreMini fibre optic pyrometer for metals and harsh, high-temperature applications

Measuring the temperature of reflective metals is a challenge. Reflective surfaces, hot furnaces and high ambient temperatures can make it difficult to achieve accurate results with non-contact sensors. The new FibreMini fibre-optic pyrometer from Calex has innovative features that are specialised for accurate measurements in this industry.
