Diaphragm Seal Pressure Transmitter Gauge

Conventional pressure transmitters face fatal application limitations in complex industrial medium environments. Ordinary diffused silicon and capacitive transmitters adopt direct pressure guiding structure, which is extremely prone to pipeline blockage, medium crystallization and residue accumulation when measuring viscous slurry, resin, syrup and particle-containing media. Direct contact with strong acid, alkali and corrosive liquids causes diaphragm corrosion, core damage and rapid performance attenuation. For ultra-high temperature process conditions, direct mounting of transmitters leads to thermal drift, circuit burnout and shortened service life. Impulse tube pressure guiding also brings hidden dangers such as liquid leakage, gas retention and inaccurate pressure transmission. The Diaphragm Seal Pressure Transmitter thoroughly solves the above industrial pain points. Based on Pascal's pressure transfer principle, it adopts an all-welded metal isolation diaphragm and fully sealed capillary filling fluid structure. The process pressure acts on the outer diaphragm surface and is accurately transmitted to the internal high-precision sensing core through incompressible vacuum filling oil, achieving lossless pressure signal conversion. The complete isolation design completely separates the transmitter core from the measured medium, fundamentally avoiding clogging, corrosion and high-temperature thermal damage. Optional remote capillary structure realizes temperature isolation and long-distance pressure collection, adapting to high-temperature equipment and difficult-to-install measuring points. With intelligent temperature compensation and digital filtering algorithm, it maintains high-precision and zero-drift output in complex variable working conditions, being the most reliable professional measuring device for harsh industrial process pressure and liquid level monitoring.

This industrial diaphragm seal pressure transmitter supports diversified personalized customization for petrochemical, chemical, pharmaceutical, food processing and metallurgical high-corrosion and high-temperature process monitoring projects. Full isolation diaphragm sealing structure prevents medium contact, completely solving blockage and crystallization problems of viscous, particle-containing and easy-solidification media. High-temperature resistant filling fluid and remote capillary design realize effective thermal isolation, supporting ultra-high temperature medium measurement up to 300°C. Multi-grade anti-corrosion diaphragm materials adapt to strong acid, strong alkali and various chemical corrosive environments. Lossless fluid pressure transmission ensures accurate and consistent pressure signal transfer without delay or attenuation. Built-in full-temperature and full-pressure compensation algorithm eliminates environmental interference and long-term drift. Explosion-proof, hygienic and high-pressure resistant industrial grades meet diversified industrial safety standards. According to project demands, we can customize diaphragm material, capillary length, filling fluid type, mounting structure, signal output mode and hygienic clamp interface to match refined measurement requirements of different harsh media and working conditions.
