The paper deals with the problem of providing the reliability of measurement information. |In the paper, a biomimetic approach to the technology of sensor devices is discussed. Efficiency of metrological self-check methods in comparison with conventional methods of metrological maintenance is shown. The advantage of the metrological selfcheck based on the evaluation of the most dangerous error component, is demonstrated. New effective methods of the metrological self-check of pressure and temperature sensors are proposed.

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.

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.
