Abstract

The invention discloses a convenient probe switching device for a coating thickness measuring instrument. The device includes a housing (1) whose hollow cross section is in a convex shape and an electromagnetic measuring end (2) and an eddy current measuring end (3) which are embedded in the housing (1). When the convenient probe switching device for the coating thickness measuring instrument is used, the electromagnetic measuring end (2) or the eddy current measuring end (3) is selected for use according to an object to be detected, when the electromagnetic measuring end (2) needs to be used, a user only needs to press the eddy current measuring end (3) downwards, so that a leaf spring (6) gathers towards the other side, the electromagnetic measuring end (2) is switched on, and the eddy current measuring end (3) is disconnected and locked at the same time, thereby realizing intelligent on-off; and if the eddy current measuring end (3) needs to be used, the user only needs to press the electromagnetic measuring end (2) downwards, the operation is convenient, and the structure is simple.

Description

technical field

[0001] The invention belongs to the field of structural design of thickness measuring instruments, in particular to a convenient switching probe device of a coating thickness measuring instrument. Background technique

[0002] Most of the existing coating thickness gauges use two independent sensor probes, one for magnetic measurement and one for eddy current measurement. Before measurement, it is necessary to determine the material of the substrate and install the probe before proceeding. For measurement, if you need to measure the substrate of different materials, you need to turn off the machine first, and then turn on the machine again after replacing the probe. The coating thickness gauge with this structure requires frequent replacement of probes and repeated switching on and off during use, which is not conducive to long-term use of the equipment, and the entire measurement work is complicated and takes a long time. When going out to work, you need to...
