Abstract (en)
[origin: EP1479910A2] A sensor membrane comprises two electrically conductive layers (2, 4) which are located below a pump membrane (1) and are separated from one another by an electrically nonconductive layer (3). The integrity of the pump membrane is ascertained by measurement of the resistance between the two electrically conductive layers. An independent claim is also included for a membrane pump for liquids with the proposed sensor membrane.
