Relative pressure sensor P21

capacitiveceramicpiezoresistive

The P21 pressure transmitter is designed for use in applications where media tend to deposit and clog the sensor. Various output signals, process connections and  high  pressure  ranges widen its area of application.  A  compact  front-flush  process  connection prevents hidden edges and drill holes,  in combination with a resistant ceramic sensor,  optimal cleaning and maintenance can be ensured.  The piezoresistive measuring principle allows for economical application in most liquid and gaseous media.  The process connection is made of high-quality stainless steel 1.4404 and is therefore suitable for  almost  all  media.  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.
