Advantages of displacement sensors for thickness measurement

Laser triangulation diffuse reflection Displacement sensor Has obvious advantages in thickness measurement:

- Very small measuring spot, which is the spot light area. For example, the spot area of ​​ZLDS10X series of Zhenshangyou Company is about 1mm. Compared with area-type non-contact capacitance and eddy current sensors, it has almost no requirements on the area of ​​the measured object and is suitable for measuring the thickness of very small area size;

- Farther measuring range starting distance. It is much larger than the starting distance of non-contact capacitance and eddy current sensors. For example, the measuring range of ZLDS100 laser displacement sensor of Zhenshangyou Company is 100mm, and the measuring distance can reach 1000mm. In this way, the sensor can be far away from the measured object, avoiding damage and thermal radiation of the measured object;

- It has a large measuring range. For example, the measuring range of ZLDS101 laser displacement sensor of Zhenyou Company reaches 2000mm, which is difficult for other sensors to achieve.

- It has nothing to do with the material of the object being measured, that is, metal and non-metal objects, non-transparent surfaces with diffuse reflection conditions can be measured.
