Relative pressure sensor P121

absolutecapacitiveceramic

The P121 pressure transmitter is designed for use in harsh industrial environments. It features a high-resolution ceramic sensor, ATEX certification, and numerous configuration options.  DNV certified,  the  sensor also finds use in marine applications and provides excellent mechanical resistance. The ceramic sensor element is resistant to aggressive and abrasive media.  The  capacitive  measuring  principle enables a  very  accurate  and  long term stable measurement,  even at  lowest pressures and high  overload resistance.  The  process  connection is made of high-quality stainless steel 1.4404  and is therefore suitable for almost all media.  For  highly aggressive chemicals,  variants  in  PP  or  PVDF  are  recommended.  Our  modular design concept provides a wide variety of products.  Feel free to contact us if you need a customization that is not listed in this datasheet.
