BEFESTIGUNGSVORRICHTUNG ZUR HALTERUNG EINER MEMBRAN ODER FOLIE

摘要

The invention relates to a membrane mounting device for mounting a membrane or foil in a stretched condition at one end of a rod-shaped or tubular member, such as a measuring electrode member. The mounting device comprises a membrane to be mounted as well as a resilient mounting ring for retaining the membrane in its mounted condition. The resilient mounting ring is preferably kept in a condition substantially free from tension. However, immediately before use of the mounting device the ring may be tensed or stretched, and one end of a rod-shaped or tubular member may then be inserted in the membrane mounting device whereby the membrane may automatically be mounted at the said end of the rod-shaped or tubular member.
