METHOD TO GENERATE STATUS OF INTELLIGENT SENSOR MEASUREMENT RESULTS Russian patent published in 2015 - IPC G01D3/00 

FIELD: measurement equipment.

SUBSTANCE: upper and lower threshold values of a reference signal are generated, besides, the lower threshold value is less than one, and the upper one is higher. Values of the reference signal are compared with threshold values, besides, if the reference signal value is in the range between the upper and lower threshold values or is equal to them, the measurement is given the status of confirmed, and if it is out of the borders defined by the upper and lower threshold values - as invalid. To generate a reference signal, the sensor outlet signal is divided into two additive components, the first of which does not depend on a noise component at the sensor inlet, and the second one is directly proportionate to it. Energy of the second sensor component is registered, and the reference signal is the ratio of the current energy of the component to the value of its energy at the moment, when the sensor operability was guaranteed.

EFFECT: possibility to assess metrological condition of a sensor of physical value in the mode of continuous technological process.
