Abstract
A membrane which is provided with a membrane surface that represents the functional region of the membrane and which is provided with a tab that projects beyond the membrane surface is described. The membrane and the tab are constructed from a number of layers, wherein at least one of the layers consists of an elastomer. Arranged in the tab is an electronic data carrier. The tab has an upper and a lower layer. The data carrier is enclosed by the layers of the tab and the upper and the lower layer.
Claims6
A membrane for a membrane valve comprising a plurality of layers, at least one of said plurality of layers is an elastomer, the membrane further including
- an upper and lower coating,
- a membrane surface, which represents a functional region of the membrane,
- a projection, which extends beyond the membrane surface, and which transverses a longitudinal side of the membrane, and
- an electronic data medium disposed in the projection, and wherein said electronic data medium is enclosed by the layers of the membrane and the upper and lower coatings.
A method for the production of a membrane for a membrane valve where the membrane has a plurality of layers, said method comprising the steps of:
- cutting an outer contour of the membrane and a projection out of the plurality of layers, wherein the projection is intended to extend beyond the membrane surface, and to transverse a longitudinal side of the membrane,
- forming a pocket as a recess in the respective materials of the individual layers;
- cutting the outer contour of the membrane, and the projection out of upper and lower coatings;
- placing individually cut-out layers on top of one another, and placing an electronic data medium in the pocket;
- and
- vulcanizing the construction of the layers of the membrane, and data medium contained therein.
