Description

The 23SX-H2 series is characterised by its low embrittlement rate due to the increased nickel content in the stainless steel used. Thanks to a gold-plated diaphragm, H2 diffusion is also reduced to a minimum. Temperature dependencies and non-linearity are precisely compensated for by means of a mathematical model in the microcontroller. In addition to the digital RS485 interface, it is also possible to output the measurement results as a scalable analogue signal. The 23SX-H2 series products are a reliable solution with a long service life, high accuracy and safety to meet all hydrogen requirements.
