Abstract

See full text

Ultrasonic pulse velocity is a parameter for assessing strength of concrete structures and studying elastic properties. A method involves transmission of longitudinal ultrasound by a transmitting transducer and receiving by a similar transducer. A transit time-measurement and associated triggering pulses provide the overall time-measurement resolution of at least 1 μs. An ultrasonic pulse velocity measuring device capable of generating ultrasound in the solid materials supporting the propagation of ultrasound and precisely measuring the ultrasonic propagation delay time or the transit time is also disclosed. An ultrasonic transit time measurement device having provision for automatic pulse threshold error correction is also disclosed. A method to realize fast counting for generation of high resolution with relatively slower microcontrollers is also disclosed. Accuracy in the transit time measurement is improved by subtracting the threshold corrected zero offset (without material under test) from the threshold corrected transit time (with sample).
