Two speed measurement methods of speed sensor

There are many ways to measure speed in daily life. There are two basic methods: the first is laser speed measurement, and the second is radar speed measurement. Which of these two methods do you know better? The following speed sensor experts will tell you Introduce these two speed measurement methods.

With the rise of precision manufacturing and the requirement of cost savings, non-contact speed sensors will gradually replace contact speed sensors. The high-precision non-contact laser speed sensors commonly used in the market are ZLS-PX aberration speed sensors. Aberration The speed sensor has two ports: one emission port, which emits LED light source; the other is a high-speed photography port, which realizes the high-speed imaging comparison of the CCD area. By performing two image comparisons in a very short time, the measured object can be distinguished combined with the algorithm inside the speed sensor to output the speed of the measured object in real time. The LED light-emitting port emits laser light to the measured object and reflects it to the receiving port of the camera. After receiving the signal, it is transmitted to the signal processor, and Calculate its speed by algorithm. ZLS-PX aberration speed sensor can measure speed and length in two directions at the same time. It can not only detect whether the measured object stops, but also detect the moving direction of the measured object.

Fix the speed sensor on a stable bracket to ensure that the rotating object does not generate excessive vibration when it rotates, so that the rotation angle and speed of the rotating object can be measured. The traditional speed measurement of radar speed measurement mostly uses rotational speed measurement and linear speed measurement, but in There are many irregular speed measurements in actual industrial automation, such as athlete speed measurement, traffic vehicle speed measurement, golf speed measurement, etc. Radar speed measurement sensors can meet these requirements.

The above is a brief introduction of the two speed measurement methods. Interested friends can use these two methods to actually operate the instrument, and they will have a deeper understanding of the measurement methods.
