Beschreibung
Zusammenfassung:	A membrane arrangement to be placed between a product chamber and a hydraulic oil chamber is provided. The membrane arrangement comprises a first membrane and a second membrane. Between the membranes in a membrane interior space a marker liquid is placed. By using a sensor it can be detected when product or hydraulic oil enters the membrane interior space, which in turn means that a rupture of any of the two membranes may be detected in a reliable and cost efficient way.
