Description

Technical Field

[0001] The present invention relates to the technical field of thickness sensors, and particularly relates to a thickness sensor. Background Art

[0002] A thickness sensor is a device used to measure the thickness of materials or objects. They have a wide range of applications in industrial production, scientific research, and daily life. There are various types of thickness sensors, including ultrasonic sensors, magnetic sensors, optical sensors, eddy current sensors, and ray sensors, etc. Among them, magnetic thickness sensors are mainly used to measure the thickness of non-magnetic coatings on magnetic substrates.

[0003] The existing Chinese patent with the publication number CN207515707U discloses a magnetic force thickness sensor, which includes a carrier plate for carrying a magnetic substrate, a magnetic force measuring head opposite to and spaced from the carrier plate to form a transmission channel, and a detection circuit connected to the magnetic force measuring head to detect the magnitude of the magnetic suction force between the magnetic force measuring head and the magnetic substrate during the process that the magnetic substrate passes through the transmission channel; the magnetic force thickness sensor further includes a first substrate, and the magnetic force measuring head includes a first magnetic force measuring head and a second magnetic force measuring head adjacent to and spaced from the first magnetic force measuring head on the setting surface of the first substrate.

[0004] In view of the above-related technologies, it is found that the existing thickness sensors have a simple detection method during measurement and use, and are affected by the accuracy of the magnetic force measuring head itself and factors such as measurement misdetection during testing, which will cause a large error in the measured results. In addition, the existing thickness sensors have a high degree of integration during use and are not easily disassembled and repaired. Summary of the Invention

When it is easy to use, the base and the top plate can be supported in parallel by the back plate, ensuring that the item to be tested can be placed between the base and the top plate during the test use, and it can be stably detected during the easy-to-use process. At the same time, by installing a magnetically conductive substrate on the upper end surface of the base, it is convenient to use the magnetically conductive substrate to cooperate with the magnetic force detection group above for magnetic detection during use. During the detection, the item to be tested needs to be placed on the magnetically conductive substrate. By arranging the magnetically conductive substrate and the magnetic force detection group on both sides of the item to be tested, the stable detection of the item can be realized through the magnetic change.
