KELLER Pressure Transmitters for H2 Applications

With their long service life and high level of accuracy, the pressure transmitters in KELLER’s 23SY-H2 series and their intrinsically safe ATEX counterparts in the 23SY-Ei-H2 range provide a reliable solution for all hydrogen applications.

The 23SY-H2 series is distinguished by its low embrittlement rate, which is due to the high nickel content of the stainless steel used to manufacture the transmitters. What’s more, the gold-plated diaphragm ensures that hydrogen diffusion is reduced to a minimum. The pressure transmitters are compensated over the entire temperature range and offer exceptional long-term stability.

KELLER series 23SY-H2 and 23SY-Ei-H2 pressure transmitters are used in a wide range of fields, including hydrogen generation and production, in transportation, in the monitoring of hydrogen refuelling stations and in the containment and storage of hydrogen.

The KELLER 23SY-H2 series offers:

  • Different accuracy classes per field of application
  • Selected stainless steel alloy for minimal material embrittlement
  • Gold-plated diaphragm for reduced hydrogen diffusion
  • Metallically sealed process connections
  • Fully welded design to prevent hydrogen leakages
  • No elastomers in contact with the measuring medium
  • Excellent long-term stability and longevity
  • Intrinsically safe ATEX version available
