Capacitive level probe P135

hydrostaticfor liquidsanalog

Due to its slim design and a diameter of  22 mm,  the  P135  level transmitter can be optimally installed in 1" pipes.  Typical applications are in the field of industrial and drinking water,  level  measurements  in  gasoline  and  oil  tanks  can  also  be  easily  implemented.  The  integrated  lightning protection shields the  ceramic sensor element from voltage peaks and ensures a long-term reliable  measurement.  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 data sheet.
