[en] Solid-state logic equipment is described for periodic ultrasonic inspection of power reactor pressure vessels. The equipment block diagram is shown. The equipment can use different types of measuring heads comprising up to 12 probes and 46 steps in one measuring cycle. The duration of one step is 250 microseconds and one cycle lasts 12.5 milliseconds. Both direct and indirect echoes can be processed depending on a preset algorithm. (Ha)
