DatasheetDescription
The membrane of the IP142 level transmitter is welded directly to the housing and does not have to be sealed internaly with an o-ring. The medium is only in contact with highly resistant CrNi stainless steel 1.4571 and there is no weakspot along an elastomer seal. The protective cap can be removed if necessary and the thread underneath can be used as a process connection. ATEX certified and with FEP suspension cable, the model is ideal for potentially critical areas and media. The measuring range can be adjusted on site using the HART interface. 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.
