Laser ranging sensor is based on the principle of triangulation

The laser range sensor is based on the principle of triangulation and is a short-range high-precision industrial application. The high-resolution displacement sensor uses the advanced digital background suppression technology to greatly improve the measurement accuracy and anti-interference ability, EMI shielding, stable signal output, strong industrial plastic casing, IP67 protection grade, strong anti-vibration impact capability. The outstanding features of this series. The high-resolution displacement sensor is small in size, easy to install, complete in function, easy to operate, with RS485 digital output function, and standard connector with M12.

The test steps are as follows:

Step 1: The transmitting probe is fixed under the non-metal plate (floor). The randomly arranged walkie-talkie is used to report the position of the transmitting probe to the host and receiving probe operator on the non-metal plate (floor). The transmitting probe does not move and the receiving probe is moved.

Step 2: During the movement, after hearing the alarm sound, draw any one of the receiving probe movement trajectory lines AB in the area where the signal is received. Move the receiving probe along the AB, find the signal value, the thickness value point O1, and record the change point.

Step 3: Pass the O1 point and make a straight line CD perpendicular to AB. As the second moving track of the receiving probe, move the receiving probe along the CD to find the signal value and the thickness value point O. This point is the center of the receiving and transmitting probe. The point is vertical, which is the true thickness value of the board. At this time, press the storage key to store the thickness of the measuring point. After storing, the measuring point number is increased by 1, indicating that the storage is completed, and the detection of the component number can be continued; press the OK button to clear the thickness of the measuring point and retest the current thickness; press return The key returns to the previous screen.
