High-pressure hydrogenation units belong to high-risk petrochemical production facilities with extreme operating conditions of high temperature, high pressure, flammable hydrogen medium and continuous cyclic operation. Interlocking protection systems are the core safety barriers to prevent overpressure accidents, equipment damage and unit runaway failures, while pressure transmitters act as the primary signal acquisition components of interlocking logic.

Continuous hydrogenation units are core production facilities in the petrochemical and fine chemical industries, operating under long-term continuous operation, high pressure, high temperature, and hydrogen-rich corrosive environments.

Slurry bed residue hydrotreating technology is a core deep processing method for heavy crude oil and residual oil in the petrochemical industry, which can effectively convert low-value heavy residue into high-quality clean oil products.

As clean hydrogen energy gains widespread adoption in transportation and industrial fields, high-precision and high-reliability pressure monitoring has become a core guarantee for the safe operation of hydrogen systems. Ordinary industrial pressure transmitters are prone to measurement failure and structural damage in hydrogen environments due to hydrogen embrittlement, gas permeation and extreme pressure fluctuations.

Hydrogen refueling units operate under extreme high-pressure, flammable, and dynamically fluctuating working conditions, where high-pressure differential pressure and pressure transmitters serve as core monitoring components for system pressure safety. During field installation, mechanical stress, pressure impact stress, thermal stress and hydrogen medium-induced structural stress frequently cause sensor zero drift, measurement deviation, and even premature equipment failure, seriously affecting the operational stability and safety of hydrogen refueling stations.

With the rapid development of hydrogen energy industry, accurate and stable pressure measurement has become a core guarantee for the safe and efficient operation of hydrogen production, storage, transportation and application systems.

With the rapid expansion of the hydrogen energy industry, hydrogen production, storage, transportation and refueling equipment have put forward higher requirements for industrial pressure measurement. Hydrogen has extremely small molecular particles, strong permeability and special chemical characteristics, which easily cause hydrogen embrittlement, sensor zero drift and equipment failure of ordinary pressure transmitters.

With the rapid development of green hydrogen energy, hydrogenation chemical engineering and hydrogen refueling infrastructure, stable pressure monitoring has become the core foundation for process safety. Hydrogen is the smallest molecule, which easily penetrates ordinary metal materials and triggers hydrogen permeation and hydrogen embrittlement. Conventional industrial pressure transmitters suffer zero drift, diaphragm damage and premature failure under long-term hydrogen exposure.

Continuous hydrogenation technology is widely adopted in petrochemical fine chemical, pharmaceutical and new energy industries, which relies on stable pressure control to guarantee catalytic reaction efficiency and production safety. As core field measuring instruments, pressure transmitters undertake real-time pressure collection, signal transmission and safety interlock tasks for continuous hydrogenation units.
