Application Overview
The document discusses the importance of precise temperature measurements in roller stands for iron and steel production. As product quality demands increase, manufacturers must ensure tighter tolerances for rolling temperatures, which have been reduced over recent years. Modern measuring instruments are essential for monitoring these parameters, especially as rolling temperatures now start at 500 °C.

Temperature Measurement with Pyrometers
Optical pyrometers are used to measure slab temperatures by detecting infrared radiation from a distance. Due to obstructions like water vapor and smoke, two-color pyrometers are recommended as they can compensate for these interferences. These pyrometers measure radiation at two wavelengths and calculate temperature based on their ratio, ensuring accurate readings despite weakened signals.

Solution: CellaTemp PA 40 AF 20
The CellaTemp PA 40 AF 20 is designed for short-wave temperature measurement starting from 500 °C. It uses advanced sensor technology and a high-luminous optical system to minimize the effects of smoke and vapor. It can handle signal weakening up to 90% for temperatures above 580 °C. Various models are available to accommodate different conditions, including limited installation space and high ambient temperatures.

Measuring Systems
The document lists several measuring systems with different pyrometer models, each with specific measuring ranges, sighting aids, and spectral ranges. These systems are tailored for various temperature ranges and installation requirements.
