DatasheetEquipped with two ceramic measuring cells, the differential pressure transmitter PD82 is particularly suitable for corrosive and abrasive media. The capacitive measuring principle enables a very accurate and long-term stable measurement. 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.
Applications:
- Gaseous media
- Liquid media
- Abrasive media
- Corrosive media
- Aggressive media
- Level measurement in superimposed pressure tanks
