In chemical production, pressure measurement faces extreme challenges-high temperature and pressure, highly corrosive media, hydrogen embrittlement risks, and potentially explosive environments. With its professional design and multi-layer protection technologies, LEEG industrial pressure transmitters have become the ideal choice for pressure monitoring in the chemical industry.

Core Advantages for Harsh Chemical Applications
- Comprehensive Diaphragm System for Diverse Media Requirements
- Offers multiple diaphragm materials including Hastelloy, tantalum, and PTFE, resistant to strong acids (e.g., sulfuric acid, hydrochloric acid), alkalis, and organic solvents
- Split diaphragm design enables measurement of high-viscosity or crystallization-prone media (e.g., polymer melts)
2. Ultra-Thick Gold Plating to Eliminate Hydrogen Embrittlement
- Sensor cavity features premium gold plating (>5μm customizable), preventing measurement drift caused by hydrogen permeation
- Delivers superior long-term stability compared to standard stainless steel, suitable for hydrogen-involved processes like ammonia synthesis and hydrogenation
3. Intrinsic Safety Protection for Hazardous Areas
- Built-in surge protection safeguards against power fluctuations and lightning strikes
- Certified with IECEx, CSA, NEPSI, and other explosion-proof standards (Ex d IIC T6), ensuring safe operation in explosive atmospheres
Typical Chemical Applications
- Reactor Pressure Monitoring
Real-time tracking of internal pressure during polymerization, sulfonation, and other reactions, with ±0.1%FS overpressure alert accuracy to prevent explosions
- Corrosive Media Pipeline Transport
Hastelloy diaphragms withstand wet chlorine gas in chlor-alkali processes, extending service life by 3X+
- Hydrogen Energy Storage & Transportation
Gold-plated sensors operate risk-free in 70MPa hydrogen environments, enabling safe hydrogen refueling station operations
- Solvent Recovery Systems
PTFE diaphragms compatible with acetone, DMF, and other solvents, paired with explosion-proof housings for full VOC process monitoring
Through material innovation and protective engineering, LEEG industrial pressure transmitters provide comprehensive measurement solutions-from ambient to ultra-high pressure, from benign to highly corrosive conditions-empowering safer, more efficient, and smarter chemical production management.
