Working principle of heating furnace furnace negative pressure gauge

Help with the working principle of the furnace negative pressure gauge of the heating furnace
The working principle is the same as the vacuum pressure gauge.
Haha, I’m not sure what you mean, it’s a diaphragm pressure gauge, which is very sensitive.
Due to the combustion in the heating furnace or the gas in the furnace being pumped away, the pressure in the furnace is less than the normal atmospheric pressure, which is negative pressure! The pressure gauge measures the negative pressure by comparing the pressure in the furnace with the atmospheric pressure!
It's the same as what I didn't say. Is there anyone who is more professional and can draw a schematic diagram of the location of the pressure pipe connection, etc.
