DatasheetThe IP131 pressure transmitter features large process connections and a front-flush measuring sensor. Clogging of the membrane is prevented most effectively and can be easily cleaned if necessary. ATEX and DNV-GL certified, the sensor can also be used in potentially explosive areas and features excellent mechanical strength. 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. The process connection is made of high-quality materials such as stainless steel 1.4404 or PVDF 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 data sheet.
Applications:
- Viscous and pasty media
- Hygiene applications
- Gaseous media
- Liquid media
- Abrasive media
- Aggressive media
- Potentially explosive areas
