Abstract

In order to make error recognition, for example, in cabling, in the stored data or in the data allocation, in the allocation of a sensor unit to sensor-relevant data for calibration of an analysis unit that is connected with a sensor unit possible, a sensor identification (6) is located in or on the sensor unit that can be polled by the analysis unit (4) and to which sensor-specific data are allocated in a storage unit (5), and a data carrier (7) is located in or on the sensor unit in which a second set of sensor-specific data are stored that can be read by the analysis unit (4) and can be compared with the first set of sensor-specific data of storage unit (5). Upon agreement of the first and second set of sensor-specific data, the measuring signals are transformed into measurement data by considering the sensor-specific data.

Claims

1. A test assembly for capturing measurement data comprising:

a sensor unit having a sensor element that supplies measurement signals,

a sensor identification provided in or on said sensor unit, said sensor identification unambiguously and individually identifying said sensor unit,

a storage unit for storing a first set of sensor-specific data allocated to the sensor identification,

a data carrier provided in or on sensor unit for storing a second set of sensor-specific data, and

an analysis unit which

(a) is connected with the sensor unit by a measuring line,

(b) polls the sensor identification of the sensor unit and reads the first set of sensor-specific data allocated to the sensor identification from the storage unit,

(c) reads the second set of sensor-specific data from the data carrier,

(d) compares the first set of sensor-specific data and the second set of sensor-specific data, and

(e) transforms said measurement signals into measurement data by taking sensor-specific data into consideration if the first and second set of sensor-specific data are in agreement.

2. The test assembly according to claim 1, wherein the sensor identification is located in or on the sensor element.

3. The test assembly according to claim 1, including a sensor plug in the sensor unit and wherein the data carrier is located in or on the sensor plug.

4. A method for capturing measurement data comprising the steps of:

capturing at least one measurement variable with a sensor unit and sending the measurement signals via a measurement line to an analysis unit,

polling a sensor identification provided in or on sensor unit with the analysis unit and reading of a first set of sensor-specific data allocated to the sensor identification from a storage unit by the analysis unit,

polling of a second set of sensor-specific data from a data carrier provided in or on sensor unit with the analysis unit,

comparing the first and the second set of sensor-specific data in the analysis unit, and

transforming the measuring signals in the analysis unit into measurement data by taking sensor-specific data into consideration if the first and second set of sensor-specific data are in agreement.
