Description
The 23SY-H2 series is characterized by low embrittlement due to the increased nickel content in the stainless steel used.
Thanks to the gold-plated diaphragm, H2 diffusion in the 23SY-H2 series is minimized. The sensors of the pressure transmitter are compensated across the entire temperature range and provide excellent long-term stability. The 23SY-H2 series products represent a reliable solution with a long service life, high accuracy and safety, meeting all hydrogen requirements.
Technical Solutions
