Your benefits

Innovative pressure sensors for monitoring and controlling tasks in hydrogen applications, e.g. for hydrogen production, storage, distribution and deployment in pipelines. The sensors must meet the highest technical requirements, mainly in terms of precision, robustness and durability, but also regarding explosion proofing (ATEX). Baumer pressure sensors for hydrogen applications meet all such requirements and featuring a gold-coated membrane they ensure extremely long durability.
