Relative pressure sensor P121 PP

absolutecapacitiveceramic

The plastic version of the P121 pressure transmitter is particularly suitable for media that lead to corrosion of stainless steel and thus to sensor failure.  The  capacitive  measuring  principle  enables  a  very  accurate  and  long-term  stable  measurement,  even  at  lowest  pressures  and  high  overload  resistance. 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 data sheet.
