In the process of using the cable displacement sensor, the fault is inevitable, the main factor is the linear error caused by the sensor circuit design, the mechanical error in the installation process and the interference of external environmental factors on the sensor detection data will also affect the accuracy of the control system to collect data.

The angular displacement sensor obtains the information brought by the outside world through the rotation and displacement of the Angle, which is sensed and transmitted by the sensor. However, many people do not know how to maintain angular displacement sensors, so there are many problems when installing and using angular displacement sensors. Then, the next vertical technology small series to specifically introduce the installation method of angular displacement sensor.

Sensor is a sensing device designed according to biological, physical, chemical and other data characteristics. In the category of automatic measurement and control, sensors designed by a certain principle can simultaneously measure a variety of non-electric power online, and sometimes a non-electric sensor can be detected by a variety of different principles, so there are many classification methods for sensors, which can be classified according to the following methods.

The core research and development staff of Polygraph Technology have more than ten years of experience in the field of laser displacement measurement and 3D scanning, and found that spectral confocal is more accurate and adaptable than laser.

Glue by its own surface tension after the surface of the curved mirror, even with the most advanced laser displacement sensor measurement, because the mirror tilt will reflect the laser away from the direction of the receiving lens, many materials simply can not produce the correct result, and installed after the dispersion confocal lens of the glue top perfect arc curve can be shown. In particular, the measurement of transparent or translucent glue is more difficult, and it is easy to measure the height of glue with a spectral confocal probe.
