As long as the size of the object, whose temperature is to measured fits with the size of the optical pyrometer, the distance between both of them is not at all a problem. Thus, the device can be used for remote sensing. This device can not only be used to measure the temperature, b...
These are one of the types of pyrometers used to detect thermal radiation of the visible spectrum. The temperature of the hot objects measured will depend on the visible light they emit. Optical pyrometers are capable of providing a visual comparison between a calibrated light source and the ta...
Special types of sensors further extend the limits to measure very low cryogenic temperatures below -200°C for applications like liquified natural gas plants, high energy physics labs. Similarly, special metallurgical thermocouples and optical pyrometer sensors go up to 3000°C for processes like stee...
Device for continuous temperature measurement of molten steel in the tundish using optical fiber and infra-red pyrometer The system developed for the continuos temperature measurement of molten metal ( 1 ), like in the case of the continuous casting machine tundish ( 2 ), uses an optical process...
The theory and technique of radiation temperature measurement with infrared fiber (bundle) at low temperature were systematically studied when the infrared optical fiber (bundle) was directly coupled with the target surface and the detector. 探讨了将红外光纤(束)直接与靶目标和探测器耦合,用于低温辐射...
