Abstract

Die vorliegende Erfindung betrifft eine Sensormembran mit mehreren sandwichartig übereinander angeordneten Membranlagen, welche eine Förder- oder Trennmembran (1), eine darunter angeordnete erste elektrisch leitfähige Membranlage (2), eine darunter angeordnete elektrisch isolierende Membranlage (3) und eine darunter angeordnete zweite elektrisch leitfähige Membranlage (4) umfassen, wobei die ersten und zweiten leitfähigen Membranlagen (2, 4) durch die elektrisch isolierende Membranlage (3) voneinander getrennt und elektrisch isoliert sind und die zweite elektrisch leitfähige Membranlage (4) Abschnitte (7) aufweist, die durch Öffnungen (5) in der elektrisch isolierenden Membranlage (3) und durch Öffnungen (6) in der ersten elektrisch leitfähigen Membranlage (2) hindurchgreifen und die elektrisch isolierende Membranlage (3) Abschnitte (12) aufweist, die durch die Öffnungen (5) in der ersten leitfähigen Membranlage hindurchgreifen.
