Description

Technical Field

[0001] The utility model relates to the field of pipeline detection, in particular to a device for measuring the length and thickness of a pipeline. Background Art

[0002] When a pipe is produced and used, its overall thickness needs to be tested to avoid the situation where some areas of the pipe are too thin, which is not conducive to the overall use of the pipe. Existing pipe thickness and length detection is mostly done manually using tape measures and ultrasonic waves. Manual detection is inefficient and cannot detect the length and thickness of large quantities of pipes.

[0003] Ultrasonic sensors measure thickness based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the material interface, the pulse is reflected back to the probe, and the thickness of the material to be measured is determined by accurately measuring the time it takes for the ultrasonic wave to propagate in the material. Length measuring sensor is a device used to measure the length or displacement of an object. It is based on physical principles and sensor technology, obtains the size information of the target object by contact or non-contact means, and converts it into electrical signals for measurement and processing. It can accurately and reliably measure the size changes of the target object. Summary of the invention
