Hydrogen Application
Series 23SY-H2
The 23SY-H2 series is characterised by its low embrittlement rate due to the increased nickel content in the stainless steel. Thanks to a gold-plated diaphragm, H2 diffusion is also reduced to a minimum. The pressure transmitters are compensated over the entire temperature range and offer excellent long-term stability. The 23SY-H2 series products are a reliable solution with long service life, high accuracy and safety to meet all hydrogen requirements.
