Transducer for e.g. determining and influencing pressure, has memory storing calibration data of sensor and/or user-specific configuration data of transducer, where data are readable from memory and/or written in memory by radio interface

摘要

The transducer (1) has a sensor (7) detecting physical or chemical parameters (8) and producing a corresponding measuring signal (10). A controlling and evaluating device (11) determines a measured value based on the signal. Exemplary specific calibration data of the sensor and/or user-specific configuration data of the transducer for the device (11) are accessibly stored in a memory (6). The calibration or configuration data are readable from the memory and/or written in the memory by a self-sufficient radio interface (3) e.g. radio frequency identification (RFID) interface.
