Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology, specifically to a device for assisting in the calibration of ultrasonic testing instruments. Background Technology

[0002] Ultrasonic testing instruments are mainly used to detect the density of concrete structures. Before testing, calibration is required. However, calibration devices specified in relevant standards are prone to problems during use, such as misalignment of the transducers and inaccurate distance readings due to excessively rigid power lines, failing to achieve the desired calibration effect and accuracy. To address this, this invention provides a new and stable device for calibrating ultrasonic testing instruments.

[0003] This invention addresses this issue by proposing an auxiliary calibration device for ultrasonic testing instruments, aiming to solve the aforementioned problems and ensure that the transmitting and receiving transducers are aligned, thereby guaranteeing the accuracy of the measurements.
