Product overview
The diaphragm pressure gauge is specifically designed for measuring pressure of non-viscous, non-crystallizing gaseous and liquid media. The diaphragm sensing element effectively isolates the measured medium, providing excellent corrosion resistance and stable long-term performance. Its compact structure, reliable operation, and high sensitivity make it an ideal choice for various industrial applications.

3. Applications
The diaphragm pressure gauge is widely used in industries requiring reliable pressure measurement for non-viscous or slightly corrosive media:
Petroleum & Chemical – Pressure monitoring in pipelines and processing equipment
Pharmaceutical & Food – Sanitary applications requiring medium isolation
Water Treatment – Filter pressure monitoring and pump systems
Machinery & Metallurgy – Hydraulic and pneumatic systems
Environmental Protection – Effluent treatment and monitoring stations
Note: For viscous, crystallizing, or highly corrosive media, optional PTFE or special alloy wetted parts are recommended.
