How to measure high temperature and pressure?
Thread Content
I have a question: I recently came across a project that involves measuring the pressure of flue gas at temperatures of 1200 degrees. Are there pressure gauges capable of measuring pressures at such high temperatures? With cooling treatment, won’t the measured pressure be inaccurate?
On the side where the instruments are located, the temperature is no longer that high, so it’s possible to take measurements.
Direct measurement is definitely not possible; it’s necessary to introduce pressure to lower the temperature before taking measurements
You can go to the heating furnace area to see how pressure is measured in a similar manner. Generally, it is measured by using a long pressure lead for cooling. It is recommended to add a protection box around the instrument. The pressure lead pipe takes slope into account.
Implement liquid isolation, a condensation ring, and a pressure transmitter
