Question/Request: Selection of pressure gauges for vacuum equipment
Thread Content
The gaseous medium produced by the process operates at a pressure of 7 KpaA; it tends to crystallize and is corrosive. What type of pressure gauge should be chosen? After checking various sources, it is said that diaphragm pressure gauges are used for low-pressure applications. However, the medium in question can crystallize, becoming impure and corrosive; will a diaphragm gauge still work in such conditions? Are there any better alternatives?
It provides control of the heating temperature; diaphragm pressure gauges are made from the same material as the equipment, ensuring a long service life. You can also check whether a flanged diaphragm seismic pressure gauge would work.
