Page 8: Instrument Design And Operation Principle
ACOUSTIC Ultrasonic tester UK1401 CONTROL SYSTEMS 1.3 INSTRUMENT DESIGN AND OPERATION PRINCIPLE 1.3.1 Design The instrument represents an electronic unit (Figure 1) enclosed into a plastic case in which two spring-driven ultrasonic transducers (transmitting and receiving) are rigidly mounted. Ultrasonic transducers have cone-type protectors. The ceramic wear proof nozzles are fixed on tops of the protectors. - Page 9 ACOUSTIC Ultrasonic tester UK1401 CONTROL SYSTEMS The lower end face panel of the electronic unit bears the fastener for the belt and an USB Micro B connector used for con- nection to a PC via the USB cable and charging of the built-in accumulator by means of the AC adapter 220 V – USB (Figure 3).

Page 10: Operation Principle
ACOUSTIC Ultrasonic tester UK1401 CONTROL SYSTEMS 1.3.2 Operation principle The instrument measures the time interval during which the ultrasonic pulse goes through the inspected object from the transmitting transducer to the receiving transducer. The ultrasonic sound velocity is determined by dividing the distance value between the points of emission and receiving points of ultrasonic waves, by the measured time value. -
