Patent ID: 8332179

Claim:
A sensor device for a fluid power apparatus, the sensor device comprising: a housing separate from the fluid power apparatus; at least one sensor for producing at least one sensor value on the basis of a property or a condition of the fluid power apparatus, the at least one sensor being disposed in the housing; and a sensor communication means for the transmission of the at least one sensor value, the sensor communication means being disposed in the housing, wherein the sensor device includes a reading means configured to obtain apparatus identification data representing at least one mechanical property of the fluid power apparatus that is not sensed in the fluid power apparatus by the at least one sensor, the sensor device being adapted for transmission of the apparatus identification data by using the sensor communication means, the sensor device being configured to convert or complement the at least one sensor value based on the apparatus identification data, the reading means being connected with a receiving means for the reception of apparatus identification data transmitted by the fluid power apparatus or reading apparatus identification data from an apparatus memory of the fluid power apparatus, said device being adapted for locating second apparatus identification data in the sensor memory on the basis of first apparatus identification data transmitted by the fluid power apparatus.
