Product catalog summary

Overview: This document discusses the challenges and solutions for optical temperature measurement in aluminium processing, specifically during extrusion, forging, and rolling. It highlights the difficulties due to aluminium's low emissivity and varying surface properties, and presents advanced pyrometer technology as a solution.

Challenges in Temperature Measurement: Aluminium is a poor source of radiant heat, making infrared radiation detection difficult, especially at low temperatures. The emissivity of aluminium surfaces can vary, affecting measurement accuracy.

Patented Measuring Method: KELLER ITS has developed a short-wave pyrometer using patented technology that can detect small photo currents, even in low emissivity conditions. This is achieved through light-intensive optics, a sensitive photodiode, low-noise signal processing, and adaptive software algorithms.

Aluminium Forging and Extrusion: Accurate temperature measurement is crucial in forging and extrusion processes to ensure quality and prevent defects. The temperature balance affects press speed and product quality, with high temperatures risking cracks and low temperatures increasing die wear.

Measuring Solutions: The CellaTemp® series pyrometers are used for temperature measurement at various stages of aluminium processing. They feature the EERC algorithm for reliable measurements across different alloys and surfaces, and are equipped with sighting options like through-the-lens, laser pilot light, or video camera.

IO-Link Interface Technology: The pyrometers support IO-Link interface for easy integration into automation systems, allowing for consistent communication and dynamic adjustment of configuration parameters during operation.

Pyrometer Specifications: The document lists various pyrometer models with their measuring ranges, sighting devices, and interfaces, highlighting their suitability for different temperature ranges and applications.

Accessories and Mountings: Details on mounting accessories and systems are provided, including cooling jackets, air purges, and mounting brackets, to ensure proper installation and operation of the pyrometers.

Contact Information: The document provides contact details for sales and service centers across various countries, including France, Italy, Austria, Russia, Spain, China, India, and Korea, as well as the headquarters in Germany.

Application note Aluminium Optical temperature measurement of aluminium The acquisition of thermal radiation for measuring the temperature of aluminium is one of the most difficult measuring tasks in radiation thermometry. On the one hand, aluminium is a very poor source of radiant heat, so that infrared radiation is extremely low, especially at low temperatures. On the other hand, the surface properties and thus the emissivity of aluminium can vary considerably. Ordinary pyrometers react extremely to such influences, so that no reliable temperature measurement is possible. Therefore, suitable...
