Is it feasible to use a water-cooled system for detecting gas pressure at high temperatures of 1100 degrees Celsius?

Excuse me, experts – who has used it and what were the results?
For measuring high-temperature gases, a thin tube is used to directly take the pressure and thereby cool the gas; by using a tube several meters long, the desired result is achieved. Using water cooling for pressure measurement is considered somewhat unnecessary, and some say it’s creating unnecessary complications, but I think it’s not entirely unreasonable. :lol. .
Thank you, handsome. The gas is slightly acidic and corrosive; it is flammable, so explosion-proof measures are required. Are there any requirements for pressure transmitters?

I haven’t worked with the 1100 model, but I have tested the 800 model under pressure; there’s no special method required – one just needs to make the pressure sensing tube longer, with a length of 1.5–2 meters being the recommended range based on experience. By the table header, it’s basically room temperature. After all, that is almost the cecum, where the medium does not flow. As for how to choose the transmitter, it depends on which explosion protection zone the transmitter’s location falls into. For Zone 0, choose IA; for Zones 1 and 2, most instruments with an explosion-proof rating will suffice. There are also gas groups and temperature groups; it’s hard to explain them in just one or two sentences.
It seems a 3 or 4-meter length is needed; Zone O requires explosion protection. Thanks to the experts
