Self-diagnostics of a system for diagnostics and monitoring (hereinafter - SDM) of hazardous production facilities ensures minimal cost of such system’s operation, metrological reliability and availability factor [1-7]. Modern SDM comprising software-hardware complexes having combination of self-diagnostic methods which decreases their reliability. The paper considers a hardware method of a SDM’s vibration measuring channel end-to-end self-diagnostics from the sensor’s sensing element to the display.
The suggested method is based on producing a test signal to the sensor circuit and its further analysis by software-hardware means [2, 5], was utilized, particularly, in development of SDM for petrochemical units.
The paper considers an approach to reliability increase of a condition monitroing system with a piezo-sensor by means of condition control for measuring-transducing channel using self-diagnostics. The paper considers selection of the most efficient parameters for self-diagnostic circuit. The results of the practical experience are presented.
