Use of high-temperature thermocouples
Thread Content
Why are high-temperature thermocouples used over time? The temperature displayed will only be lower than the actual temperature. It will never show high...........
High-temperature thermocouples are generally made of materials that are resistant to oxidation or reduction; over time, an oxide film or a film formed by the reduced material will develop, which causes the displayed temperature to be lower than the actual temperature. I wonder where your high-temperature thermocouple is used. Personal opinion.
Used to measure the temperature of the vaporization furnace. Temperature measurement: ~1350 degrees, using B-type standard thermocouple material
For 1350, double platinum-rhodium should be used, right? It is recommended to buy thermocouples of better quality.
How does the original poster know whether it’s too high or too low?
Big brother. There are 3 more. It’s okay to compare, right...
Could you please tell me what material the thermometer sleeve is made of, and what is its service life? Thank you
As long as the thermometers are installed more than 5 centimeters apart and have different insertion lengths, it is difficult to draw any conclusions.
