[0024] A displacement sensor, also known as a linear sensor, is a metal-sensing linear device that converts various measured physical quantities into electrical quantities. In the production process, displacement measurement is generally divided into two types: measuring physical dimensions and mechanical displacement. Depending on the form of the measured variable transformation, displacement sensors can be divided into analog and digital types.

[0025] However, the installation site of the displacement sensor is not always flat. In some cases where it is installed on a non-flat workpiece, measurement difficulties may occur, which is not conducive to the normal installation and use of the displacement sensor.

[0026] First, place the sensor 10 inside the inner mounting seat 2, and then connect the outer mounting seat 1 to the workpiece to be measured.
