摘要： 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.

摘要翻译： 滚动轴承包括在滚道运行期间滚动的多个滚动体。 为了减少轧制过程中的摩擦，通常为滚动轴承提供润滑剂。 然而，润滑剂的质量由于长时间的应力，老化或热影响而在操作期间劣化，或者在间隙等中损失。本发明所提出的目的是提供一种传感器装置，其可以在 功能可靠的方式。 该目的通过一种传感器装置实现，该传感器装置用于监测润滑剂室中的润滑剂的状态，包括发射台，其中在发射台上配置有多个二极管装置，具有测量窗口装置，其中测量窗口装置 布置在测量室和具有接收装置的润滑剂室之间，其中至少一个二极管装置包括模具和塑料圆顶。 塑料圆顶和模具通过接触表面连接，其中接触表面设置在模具的上侧。
