Abstract: Terms and definitions in the field of sensors and measuring systems with the elements of artificial intelligence are not well-established. Nowadays, in Russia a draft of state standard “Intelligent Sensors and Intelligent Measuring Systems. Basic Terms and Definitions” is being under development. In accordance with the draft of the standard, the paper deals both with definitions and grounds of a number of terms such as “adaptive sensor”, “metrological self-check of sensors”, “metrological diagnostic check”, “intelligent sensor”, etc.

Abstract: A number of new problems of measurement assurance of computerized measuring instruments at the stage of development, production and operation stages are discussed. Possible solutions are outlined taking into account the experience of the D.I. Mendeleyev Institute for Metrology.

Abstract: Technical solutions applied to a special complex for measuring position of a control rod in the primary coolant circuit of nuclear reactor are considered. These solutions have provided an increased accuracy, sensitivity, fault-tolerance, and lifetime. The primary transducer lifetime is comparable with reactor lifetime. The measuring complex also carries out developed self-diagnostics and diagnostics of a drive that moves the control rod. The results of the measuring complex use are analyzed.

Abstract: Modern knowledge-intensive branches of industry require industrial intelligent sensors with enhanced metrological reliability. Such sensors are expected to provide many years of operation without maintenance. The specific scientific problems that emerge while developing such sensors are considered. These problems include: experimental evaluation of quality of sensor design and technology; development of on-line strategies for metrological self-checks of sensors as well as of methods to provide self-correction and fault-tolerance. Possible ways of solution of these problems are outlined.

Abstract: It has been proved that artificial intelligence leaned on self-checking is an efficient factor for increasing metrological reliability of measuring instruments. The possibility to create intelligent measuring instruments based upon redundancy of measurement information and informational redundancy of a measuring transducer is presented. Practical examples are provided.
