Annotations languages:

The problem of an application of the theory of measurement uncertainty for assessment of the instability of the metrological characteristics of measuring channels was considered. The main reasons of the parametric failures of the main types of sensors of measuring channels were presented. The factors affecting the instability of metrological characteristics of measuring channels were formulated. The group of the impacts for investigation of instability of metrological characteristics of measuring channels was proposed . Pre-invited to consider the metrological model of the measurement channel based on the theory of uncertainty of measurements.
Keywords: the measurement channel, the instability of metrological characteristics of uncertainty of measurements, the metrological model
