HLVH
ZYZL
ZYZL-HLVH
HLVH hydrogen pressure sensors for monitoring and controlling tasks in hydrogen applications, e.g. for hydrogen production, storage, distribution and deployment in pipelines. The sensors must be compatible with hydrogen, with corrosion-resistant 316L stainless steel to prevent hydrogen evolution or hydrogen extraction.
Mainly in terms of precision, robustness and durability, but also regarding explosion proofing (ATEX). ZYZL pressure sensors for hydrogen applications meet all such requirements and featuring a thick film one body without welding line or O-ring, they ensure extremely long durability and advoid risk of leakage.
Features
- - Dedicated for hydrogen pressure measurement
- One body sensor, no o-ring, no welding and no risk of leakage
- Thick film sensor to prevent hydrogen evolution
- All 316LSS wetted parts to resist hydrogen embrittlement
- Explosion proof certification (on pending)
-
Applications
- Hydrogen storage tank with high pressure
- Hydrogen station
- Hydrogen plant
- Source of water
- Water pump
- Microfiltration system
- H2 electrolyzer
- H2 Piping
- H2 Dryer
- H2 compressor
- H2 storage system
- H2 filling station for the transport sector
- H2 conversion into electricity by stationary fuel cells for industrial and domestic purposes
- Pressure monitoring in the distribution network
