In some specific embodiments, the label paper 2 is further provided with a limit mounting portion 21, and the sensor 1 is disposed in the limit mounting portion 21. That is, the limit mounting portion 21 is used for limiting the mounting position of the sensor 1 on the product to be tested, and the alignment mark 22 is mainly used for determining the mounting position of the sensor 1. By the limitation of both the limit mounting portion 21 and the alignment mark 22, the position of the sensor 1 provided on the product to be measured can be uniquely determined. It will be appreciated that, in order to facilitate the determination of the mounting position of the sensor 1 on the product to be measured and the adjustment of the orientation of the sensor 1 when the sensor 1 is mounted, the alignment mark 22 is located outside the limit mounting portion 21. The alignment marks 22 are thus also visible when the sensor 1 is mounted to determine the mounting position of the sensor 1 on the product to be measured.

In some more specific embodiments, the limit mounting portion 21 is a hollowed-out portion, and the alignment mark 22 is disposed on the marking paper 2 outside the hollowed-out portion.

The connection back adhesive paper 35 is provided with a mounting limiting part 351, and the mounting limiting part 351 is used for limiting the fixed position of the magnetic seat and is convenient for a tester to distinguish. It can be understood that the fixed magnetic seat 3 is stuck or magnetically attracted in the installation limiting portion 351 according to the magnetic property of the product to be measured.

In some specific embodiments, the connection back adhesive paper 35 is provided with an alignment mark 352, the mounting limiting portion 351 is hollow, and the alignment mark 352 is located at the outer side of the hollow. Wherein the alignment mark 352 is aligned with the alignment mark 22.
