Laser sensors (linear displacement sensors) are sensors that use laser technology for measurement. It consists of a laser, a laser detector and a measurement circuit. Laser sensor is a new type of measuring instrument, the use of laser with high directivity, high monochromism and high brightness characteristics, its advantages are to achieve non-contact long-distance measurement, fast speed, high precision, large range, anti-light, electrical interference ability.

Laser sensors are often used for the measurement of physical quantities such as length, distance, vibration, speed, orientation, etc., and can also be used for flaw detection and air pollutant monitoring.

Laser displacement sensors for belt production quality detection Harsh industrial environments have high requirements for optical displacement sensors. In spite of dust and high speed work, accurate measurements are still needed.

Laser sensors have been used to address these challenges for many years. However, if the resulting motion interference (band motion, pulley radial motion, and matrix vibration) is greater than the measured signal, the measurement process may be obstructed or unmeasurable. The crease of a ribbon is one example.

Here the universal controller compensates for the fundamental motions associated with the process by applying relative limits. The first average is generated from the last measurement. This provides a baseline for the values currently measured by the sensor. Therefore, the value is recognized as substantial only if it exceeds a limit related to the mean value. This ensures that small distance changes can be detected despite intense movement.

advantage

1, the tube has strong interference movement in the process, the target recognition is still reliable

2, fast, accurate, high separation rate measurement

3, to solve - no system control operation

Because of its high measurement accuracy and non-contact measurement characteristics, laser displacement sensor is widely used in universities and research institutions, automotive industry, machinery manufacturing industry, aviation and military industry, metallurgy and material industry precision measurement and detection. The laser displacement sensor can accurately measure the position, displacement and other changes of the measured object without contact, which is mainly used in the measurement of the displacement, thickness, vibration, distance, diameter and other geometric quantities of the detected object.
