Diaphragm Seal

SJ Gauge offers a wide range of diaphragm seal solutions for pressure gauges and pressure transmitters, including single flange, double flange, sanitary type, threaded type, and special diaphragm seals, which can be selected based on different media characteristics and installation requirements.

When the measured media is viscous, paste-like, crystallizing, particle-containing, or highly corrosive, diaphragm seals help protect pressure instruments by reducing the risk of clogging, corrosion, and damage, while improving measurement stability. Common applications include chemical processing, food and beverage, pharmaceutical, wastewater treatment, petrochemical, and various process industries.
