Novel coating thickness gauge probe

Abstract

The invention discloses a novel coating thickness gauge probe which comprises an outer casing body and a probe. A through hole is arranged in the front end of the outer casing body. The inner diameter of the through hole is consistent with the outer diameter of the probe. One end of the probe extends out of the outer casing body, and the other end is arranged in the cavity of the outer casing body. The probe is connected with a circuit board which is arranged in the cavity of the outer casing body through a signal wire. The circuit board is connected with the monitoring terminal of a thickness gauge through a signal wire. The novel coating thickness gauge probe further comprises a buffer component which is arranged between the probe and the circuit board, and an air blowing component which comprises an air pipe and a miniature air pump. Air blowing holes are arranged on both sides of the through hole in the front end of the outer casing body. One end of the air pipe is fixed in the air blowing holes, and the other end is communicated with a micro air pump arranged outside the outer casing body. A shielding sheet is fixedly arranged on the inner wall of the outer casing body. According to the invention, the novel coating thickness gauge probe has the advantages of simple structure principle and good buffering effect; the probe is prevented from being damaged; air is blown to the surface of the probe to remove dust; the thickness measurement precision is improved; in addition, the novel coating thickness gauge probe has an electromagnetic shielding function, which further improves the thickness measurement precision.

Description

technical field [0001] The invention relates to the technical field of thickness gauges, in particular to a novel coating thickness gauge probe. Background technique [0002] Coating Thickness Gauge can non-destructively measure the thickness of non-magnetic coatings on magnetic metal substrates and the thickness of non-conductive coatings on non-magnetic metal substrates. The coating thickness gauge has the characteristics of small measurement error, high reliability, good stability, and easy operation. It is an indispensable testing instrument for controlling and ensuring product quality. It is widely used in manufacturing, metal processing, chemical industry, Commodity inspection and other testing fields, and the probe of the coating thickness gauge is the most important part, which affects the measurement efficiency and measurement accuracy. According to the measurement principle, coating thickness gauge probes are generally divided into magnetic thickness measurement p...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the probe of the coating thickness gauge is directly attached to the surface of the product for measurement. If the force is too large during the measurement process, it is easy to damage. In addition, the probe is exposed In the air, it is easy to have dust covering the surface, which affects the measurement accuracy
