Introduction
Concrete crack depth tester mainly is used to test crack depth and sound wave propagation velocity in concrete according to sound wave diffraction propagation principle. It is a intelligent Instrument incorporating functions such as testing, saving and transmitting data.
Work Principle
Crack depth sounder composed of the signal transmitter, receiver, signal processor, display, keyboard, data transmission unit. The first signal transmission unit to the concrete internal launch ultrasonic receiver transducer receives the ultrasonic signal, the signal processing unit for processing the received signal, the transceiver spacing conversion depth of the cracks and display, storage.
