FIELD: physics.
SUBSTANCE: group of inventions relates to a method, apparatus and a system for assessing the normal or abnormality of a measured physical parameter of a device. For evaluation, reference values for operating parameter of device are stored in data storage means, by means of data processing means, estimated value of parameter is calculated in certain manner, corresponding error is calculated, calculating estimated value of dispersion of physical parameter for value of operating parameter, contribution of anomaly of measured value is calculated, anomaly of measured value is compared with threshold, when threshold is exceeded measurement is displayed as abnormal on interface facilities. Apparatus comprises data storage means and data processing means for realizing the method. Proposed system comprises test bench including transducer and device to house said device and equipment to estimate measured parameter.
EFFECT: higher reliability and efficiency of monitoring parameters associated with the engine, detection of distortions among the set of measurements.
