Relative pressure sensor P131

absolutecapacitiveceramic

The  P131  pressure  transmitter  features large process connections and a front-flush measuring sensor.  Clogging  of  the  membrane is prevented most effectively and can be easily cleaned if necessary. ATEX and DNV-GL certified, the sensor can also be used in potentially explosive areas and features excellent mechanical strength.  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 materials such as stainless steel  1.4404 or  PVDF and is therefore suitable for almost all media.  Our  modular design concept provides a wide variety of products.
