Relative pressure sensor P126

absolutecapacitiveceramic

The  P126  transmitter is characterized by its on-site adjustment capability.  The  measuring  range can be fine-tuned subsequently and the cable is connected directly to the integrated clamps. Teach-in of filling levels is therefore quick and uncomplicated to perform. 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.  Its housing 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.
