Endevco and National Instruments are developing plug-and-play sensors. The sensors have in-built low-cost memory chip that contains information about the transducer stored in the Transducer Electronic Data Sheets (TEDS). Information such as calibration data will be automatically read by a signal conditioner or analyzer, thereby eliminating calibration errors. The TEDS format conforms to the IEEE standard P1451.4, which was in part developed by National Instruments.
