Abstract | The invention relates to a measuring device (1) for measuring a measurement variable of a fluid, in particular a sensor, such as a pressure sensor, a relative pressure sensor, a differential pressure sensor, a travel sensor or the like, having a housing (2). An elastic diaphragm (8) is arranged in and/or on the housing (2). A signal transducer interacts with the diaphragm (8) such that the action of the fluid on the diaphragm (8) effects a measurement signal, corresponding to the measurement variable, at the signal transducer. The diaphragm (8) comprises an electrically conductive elastomer layer. The action of the fluid on the diaphragm (8) effects a change in the electrical capacitance of the diaphragm (8). The diaphragm (8) is operable as a signal transducer by virtue of the change in capacitance of the diaphragm (8) being provided as a measurement signal. |
