About The MPM480GH Pressure Transmitter
The MPM480GH pressure transmitter is purpose-built for hydrogen measurement in gas industry applications. Featuring a gold-plated stainless steel diaphragm, it effectively prevents hydrogen permeation, ensuring long-term stability and reliability. The all-welded stainless steel construction delivers robustness and durability, while accuracy levels reach up to ±0.25% FS for critical applications.
Usage conditions
Engineered for demanding environments, the MPM480GH provides:
- Pressure ranges from 250 mbar to 70 bar
- Overpressure tolerance up to 1.5x FS
- Operating temperature: -30°C to +85°C (depending on connection type and cable material)
- Shock resistance: 20 g / 11 ms and vibration resistance: 20 g (20–2000 Hz)
- IP65 protection rating for harsh conditions
Possible applications
- Hydrogen production plants
- Hydrogen storage facilities
- Fuel cell systems
- Industrial gas handling and process control
