| 摘要 |
A sensor system for determining a physical, measured variable, and includes a sensor and a control/evaluation unit, which are spatially separated from one another and electrically conductively connected via a cable having at least two conductors, wherein provided in the sensor are a temperature measuring element for determining temperature and a sensor identifier for sensor identification. The control/evaluation unit drives the temperature measuring element and the sensor identifier via a shared conductor with a positive voltage or a negative voltage, and, depending on the applied voltage, reads a temperature measured value of the temperature element or an identifying value of the sensor identifier. |
