Taimanov R. E., Sapozhnikov K. V. The problems of creating new generation intelligent sensors
The paper is a version of the authors’ contribution to the 10th IMEKO TC7 International Symposium “Advances of Measurement Science” (June–July 2004, St. Petersburg). It indicates that the industry needs nonelectrical quantities sensors with high integrity of measurement information, improved metrological reliability and increased lifecycle without maintenance. The paper shows that new generation intelligent sensors meet these requirements. Key development trends of such sensors are discussed.
