Equipment technical state monitoring systems contain hundreds of vibration and temperature sensors for real-time condition monitoring of machinery.
Monitoring systems reliability should significantly exceed the units stock reliability, being protected from accidents and incidents.
The paper considers the approach to monitoring systems reliability growth, primarily by means of providing control (monitoring) of measuring-converter path technical condition.
Sensors are the weakest point, due not only to wear, but also to damage, caused by repair personnel when servicing equipment.
The self-diagnostics method for channels with piezoelectric transducers and the choice of optimal self-diagnostics circuits parameters have been suggested.
The results of practical implementation have been provided as well.
