Industrial laser ranging sensor is a device that uses laser technology for high-precision, non-contact distance measurement. Industrial laser ranging sensor is a high-precision, non-contact measuring device widely used in industrial automation, robotics, logistics, automotive manufacturing and other fields. Its working principle mainly utilizes the linear propagation characteristics of the laser beam. By measuring the time or phase difference of the laser beam from the emitter to the target object and then reflecting back, the distance between the emitter and the target object is calculated.
The specific principles are divided into two types: pulse type and phase type:
Pulse type: A pulsed laser beam is emitted, and when the laser beam encounters the target object, it is reflected back. The sensor receives the reflected light, calculates the time difference between emission and reception, and multiplies it by the speed of light to obtain the distance between the sensor and the target object.
Phase based: A continuous laser beam is emitted, and the distance is calculated by measuring the phase difference between the emitted light and the received light. Phase laser ranging sensors have the characteristics of high precision and high resolution, and are suitable for short distance measurement.
Product Features
High precision and high resolution: The measurement accuracy can reach ± 1.5mm to ± 5mm, with a resolution of up to 0.1mm, suitable for precision industrial scenarios.
Fast response: The sampling frequency can reach 10Hz to 100Hz, capturing real-time changes in the position of dynamic targets.
Non contact measurement: avoids damage to the target object caused by mechanical contact, suitable for high temperature, high pressure, or vulnerable surfaces.
Strong anti-interference ability: The laser has good monochromaticity, is not affected by ambient light, color, or material, and has high stability.
High protection level: Suitable for harsh environments such as high temperature, dust, and humidity.
Laser ranging sensors have broad application prospects in measurement, control, monitoring, and other fields due to their high precision, high speed, and high reliability. In the future, laser ranging sensors will play a more important role in robots, unmanned aerial vehicles, autonomous vehicle, intelligent manufacturing and other fields.
