Nowadays, there are more and more brands of laser displacement sensors, which well meet the current domestic market demand, and also reduce the cost of use. With the development and improvement of domestic science and technology, domestic brands of laser displacement sensors show their own value and reliability. In the monitoring of parameters such as bridge beam displacement, cracks, support displacement, beam stress, deflection, ambient temperature and wind direction, displacement is one of the important parameters of structural monitoring. In order to avoid the shortcomings of contact displacement sensors such as low accuracy, easy wear and poor long-term stability, professional laser displacement sensors are often used.

So why are laser displacement sensors popular? The following is introduced by Shenzhen Liyi Technology:

1. Easy adjustment of light intensity

In practical applications, due to the difference in working environment, light intensity or diffuse reflection of the surface of the measured object, the light intensity accepted by the image point on the laser displacement sensor is also different, resulting in the output video signal of the image point position is strong and weak, which causes great difficulties for the subsequent signal processing. The laser displacement sensor should adjust the light intensity of the emitted laser according to the material and surface conditions of the measured object and the measurement environment, so as to adjust the strength of the output signal of the laser displacement sensor. Domestic laser displacement sensors have this advantage.

2, the measurement error is small

In the working process of the displacement sensor, some errors will inevitably occur, which will affect the application range of the laser displacement sensor. On the basis of in-depth analysis of the working principle of the triangulation method in the current measurement of the laser displacement sensor, according to the practical application requirements, the measurement error trend of the front laser displacement sensor is modeled by using the two-vector support machine, which can accurately estimate the measurement error of the front laser displacement sensor and better fit the measurement error change characteristics of the optical displacement sensor.

3, a wide range of applications

When the laser displacement sensor is used in the frozen soil laboratory test, the displacement range is small and the precision is high. The laser triangulation method is mainly used. Because the environmental conditions of the frozen soil test are not ideal, the linearity of the ordinary displacement sensor will be reduced. Therefore, when the laser displacement sensor is used in the permafrost test, it is not affected by the harsh environment of the permafrost. Displacement monitoring is one of the important contents of rail transit bridge monitoring. Laser displacement sensor accuracy, so that the majority of consumers favor.

Above why are laser displacement sensors popular? Compared with ordinary sensors, laser displacement sensors have the advantages of fast measurement speed and non-contact, and have been successfully applied in many reverse engineering fields such as complex surface detection.
