DatasheetDescription
The IP20 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.
