Stainless Steel Diaphragm Pressure Gauges | Chemical & Sanitary Applications
Product Overview: Precision for Demanding Media
Our stainless steel diaphragm pressure gauges are engineered for applications where standard Bourdon tube gauges cannot perform. Featuring diaphragm seal protection, these membrane pressure gauge instruments isolate the internal mechanism from process media—ideal for viscous, corrosive, or crystallizing fluids.

Key Benefits
Diaphragm Seal Protection: Prevents clogging and protects against corrosive or viscous media—essential for any chemical pressure gauge
Vibration & Spike Damping: Liquid fill dampens vibration and pressure spikes, preventing transfer to internal mechanism
Heat Fin Option: Sanitary model with heat fin isolates high-temperature processes
All Stainless Steel: Maximum corrosion resistance for harsh environments
Typical Applications
Chemical processing plants
Pulp and paper manufacturing
Food and beverage production
Pharmaceutical bioreactors
Wastewater treatment
