Patent ID: 8789424

Claim:
A method for manufacturing measuring transducers, especially pressure or pressure difference measuring transducers, with: a memory readable and writable via an associated RFID interface, at least one sensor for registering a physical, measured variable and for transducing such into an electrical variable, which sensor is equipped with a sensor electronics, said sensor electronics serving to condition the electrical variable into an electrical measurement signal dependent on the measured variable, and which is equipped with an RFID transponder, for supplying the sensor with energy via said RFID transponder, and for reading out the measurement signals wirelessly via said RFID transponder, the method comprising the steps of: subjecting the measuring transducers and/or their sensors to at least one calibration and/or test procedure; exclusively supplying the sensors with energy via their RFID transponders; reading out their measurement signals via their RFID transponders; deriving transducer specific and/or sensor specific data based on the calibration and/or test procedures; and storing said transducer specific and/or sensor specific data in the memory via the RFID interface.
