<p>A method for manufacturing measuring transducers, especially pressure or pressure difference measuring transducers, in which a high degree of quality, safety and accuracy of measurement is achievable with little logistical and manufacturing effort. The measuring transducer has a memory readable and writable via an associated RFID interface, and at least one sensor for registering a physical, measured variable and for transducing such into an electrical variable, wherein the sensor is equipped with sensor electronics, which serves to condition the electrical variable into an electrical measurement signal dependent on the measured variable, and which is equipped with an RFID transponder, via which the sensor is supplied with energy, and via which measurement signals can be read out wirelessly. The measuring transducers and/or their sensors are subjected to at least one calibration and/or test procedure, in which the sensors are exclusively supplied with energy via their RFID transponders, and their measurement signals are read out via their RFID transponders, and measuring transducer specific and/or sensor specific data derived during the calibration and/or test procedure are stored in the memory via the RFID interface.</p> |
