Gold Plated Diaphragm Differential Pressure Sensor Corrosion Resistant

Gold-Plated Diaphragm Corrosion-Resistant Differential Pressure Sensor

The Gold-plated diaphragm differential pressure sensor is a precision measurement device tailored for highly corrosive working conditions. It features a core high-purity gold-plated diaphragm: its dense gold-plated layer can stably resist long-term erosion from strong acids, alkalis, and strong oxidizing media. Combined with a fully sealed stainless steel main structure, it maintains continuous and accurate differential pressure sensing capability in extremely corrosive environments, adapting to measurement needs in various harsh corrosive scenarios.

1. High-purity gold-plated diaphragm: The dense gold-plated layer resists long-term erosion from strong acids, alkalis, and strong oxidizing media, with corrosion resistance far exceeding conventional metal diaphragms
2. Dual protection (gold plating + full sealing): The gold-plated diaphragm combines with a fully sealed stainless steel main body to isolate corrosive media penetration, adapting to extreme corrosive working conditions
3. High stability in corrosive environments: The gold-plated film layer does not react with corrosive media, and maintains precision fluctuation within ±0.05%F.S. after long-term use
4. Multi-medium corrosion-resistant compatibility: Stably adapts to differential pressure measurement of strongly corrosive fluids/gases (e.g., sulfuric acid, nitric acid, chlor-alkali) without frequent sensor replacement
5. Long-lasting gold-plated layer: The diaphragm’s gold-plated layer has strong bonding force, with no risk of falling off or cracking under alternating high/low temperatures and pressure fluctuations
