Messer Hydrogen Plant: E+H Pressure Transmitter Solves High-Temperature, High-Pressure Hydrogen
2026/05/25
Permeation Challenge Project Background:
Messer's industrial gas steam reforming hydrogen production facility operates at temperatures up to 900°C and pressures reaching 200 bar, with a furnace environment maintained at millibar-level low pressure. Under these conditions, hydrogen easily diffuses into sensors, causing drift and failure.
Key Challenges:
- Extreme operating conditions: high temperature, high pressure, and hydrogen permeation;
- Poor stability and significant drift in micro-pressure measurements;
- Requirement for long-term maintenance-free operation and high safety standards.
Selected Product:
Endress+Hauser Cerabar PMP71B (same platform as PMP55) pressure transmitter featuring a 25 μm gold-plated diaphragm, HART + Bluetooth communication, and SIL2 certification.
Application Results:
- The gold-plated diaphragm completely prevents hydrogen penetration, enabling 24 months of continuous operation with zero drift and zero failures;
- Micro-pressure measurement accuracy reaches ±0.075% at millibar levels;
- Remote configuration via Bluetooth reduces maintenance time by 60%;
- Established as a benchmark solution in the hydrogen production industry.
