What does a wind-proof plug for a vacuum gauge look like?
Thread Content
The negative pressure chamber of the furnace negative pressure gauge is connected to the atmosphere; it fluctuates whenever there is wind, so a wind-proof plug needs to be installed. It would be helpful to have pictures showing what such a plug looks like; thank you!
If the selection is fine, you can try running the tube at the negative pressure end straight downward; or if the negative pressure gauge comes with a plastic seal, cover it and make a few holes in it
It’s just a thread plug; you can also wrap it up to prevent external interference
