A detector arrangement, for selective detection of vibrations on a component, comprises a film fitted with at least one piezoelectric element. The film is attached to the component in such a way that occurring mechanical vibrations act on the piezoelectric element, such that an electrical charge with a frequency correlating with the mechanical vibration is generated at the connection electrodes of the piezoelectric element. An electrical filter is connected to the piezoelectric element and filters out the component of the supplied charge which corresponds to a predefined frequency. An electrical charge storage means which is connected to the filter is used to accumulate the filtered-out charge components. A signaling means is also provided, which generates an electrical signal as soon as a predetermined charge limit value is reached on the charge storage means.

Rolling bearings include a plurality of rolling bodies which during operation roll on raceways. In order to reduce friction during rolling, it is customary to supply the rolling bearings with a lubricant. However, the quality of the lubricant can deteriorate during operation due to long-term stress, aging, or thermal influences, or get lost in gaps etc. The objective addressed by the invention is that of providing a sensor device, which can be operated in a functionally reliable manner. This objective is achieved by a sensor device for monitoring the state of a lubricant in a lubricant chamber, including a transmitter platform, wherein on the transmitter platform, a plurality of diode devices are arranged, having a measurement window device, wherein the measurement window device is arranged between a measuring chamber and the lubricant chamber, having a receiving device, wherein at least one of the diode devices comprises a die and a plastic dome. The plastic dome and the die are connected by way of a contact surface, wherein the contact surface is arranged on an upper side of the die.
