DETECTOR OF ULTRASONIC TRANSDUCERS SERVICEABILITY Russian patent published in 2008 - IPC G01N29/22 

FIELD: electricity.

SUBSTANCE: inlet and outlet of one of the ultrasonic transducers, which are installed in one casing with provision of electromagnetic connection between electric circuits of transducers, is also connected with signal inlet of probing pulses parameters measuring unit, with inlet of rectifier and outlet of pulse generator, outlet of rectifier through stabiliser of voltage is connected to inlets of pulse generator supply and probing pulses parameters measuring unit, at that the latter consists of peak detector, comparator, clock oscillator, analog to digital converter, counter and microprocessor, at that signal inlet of probing pulses parameters measuring unit is the inlet for peak detector and comparator, outlet of peak detector is connected to inlet of analog to digital converter, outlet of comparator is connected to inlet of counter, at that outlets of analog to digital converter and counter are connected to corresponding inlets of microprocessor, besides, outlet of clock oscillator is connected to other inlets of analog to digital transducer, counter and microprocessor, and outlet of microprocessor, which is the outlet of probing pulses parameters measuring unit, is connected to control inlet of pulse generator, also detector consists of synchronous pulses generator, which provides synchronisation of all ultrasonic transducers operation, and also of blocks and units in time.

EFFECT: provision of operative registration of faulty ultrasonic transducers in order to reduce time for detection and disconnection of faulty transducers.
