Relative pressure transmitter P20

capacitiveceramicanalog

The  P20  pressure  transmitter model is designed for use in applications where media tend to deposit and clog the sensor.  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  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. 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.
