Air conditioning and refrigeration industry

Principle of Stress (Piezo) thin film vacuum gauge: Stress sheet (Piezo) thin film vacuum gauge is to sense the change of force on the designed film through the stress plate, and know the current gas pressure.

Piezoelectric effect principle: When some dielectrics are deformed by external forces in a certain direction, due to the polarization phenomenon of internal charges, a charge with opposite polarity will be generated on their surface accordingly. When the external force disappears, it returns to an uncharged state.
