FIELD: measuring equipment.
SUBSTANCE: method of diagnostics using a field installed device and identification of a diagnosed state in the industrial process in response to this comprises the following stages: measuring infrared radiation from a place in the industrial process using an array of infrared sensors containing a number of infrared sensors; comparing an output signal from the first section of the sensor array with an output signal from the second section of the sensor array; providing an output signal indicating a diagnosed state in response to the comparison, on the basis of the ratio between the output signal from the first section of the sensor array and the output signal from the second section of the sensor array determined at the comparison stage.
EFFECT: identification of anomalies in the industrial process based on thermal images.
