Laser speed measuring system:

Product introduction

In related industrial automation production, precise length measurement and precise speed measurement and control are necessary to optimize the production process. Due to its “non-contact” measurement characteristics, there is no wear and tear, which can not only minimize the maintenance cost of the production line, but also significantly improve the reliability of the assembly line, improve production efficiency and product quality, ensure accurate product specifications, and greatly reduce production. cost, can improve the company’s competitive advantage.

 

Metallurgical industry:

  • ZK-D-SC/H/L series The system is suitable for the manufacture of various metal products such as bars, tubes, wires, plates, strips, hot rolling, cold rolling, etc., real-time online accurate measurement of speed and length, And can measure 1000 ℃ high temperature billet.
  • ZK-D-SL1500, dedicated for continuous casting production line, can measure 1000 ℃ high temperature steel billet, adapt to lower speed measurement and adopts automatic light intensity gain function for the surface of iron oxide scale, the measurement accuracy can reach ±0.1%.

 

  • Cable and other industries:

ZK-D/S-W300 measures cables of various outer diameters and shapes, including stranded wires, crimped wires, etc., the measurement accuracy can reach within 0.03%, and the minimum diameter of 0.25mm optical fiber can be measured

 

Train speed measurement and train positioning

  1. ZK-D-RT500-NS can realize speed measurement in the range of 0-160km/h, and the minimum speed measurement can reach 0; it is suitable for speed measurement and positioning of low-speed rail trains such as subways and urban rails.
  2. ZK-D-RT500-HS can realize speed measurement in the range of 0-400 kilometers, and the minimum speed measurement can reach 0; it is suitable for high-speed speed measurement and positioning such as high-speed trains.
  3. ZK-D-RT500-SS can realize speed measurement in the range of 0-1100 kilometers, and the minimum speed measurement can reach 0; it is suitable for speed measurement and positioning of ultra-high-speed maglev trains.

 

Advantage:

  • Pulse-triggered camera for visual defect recognition

While the laser Doppler velocimeter measures the speed and length of the object online, the editable pulses sent by the velocimeter are used to trigger the camera to collect images. No matter how the speed changes, it will ensure that a clear image of the surface of the object to be measured is collected in equal proportions. achieve defect identification.

 

  • Speed and position information such as laser coders are provided

The laser Doppler velocimeter can accurately give accurate speed and position information, and the text patterns, logo marks, two-dimensional codes, etc. processed by the editable pulse-driven laser coding machine have high precision, and the processing effect is uniform.

 

  • Instantaneous speed measurement: ultra-fast sampling frequency, 50,000 times/second

ZK-S- InstantaneousSpeed This type of speedometer is suitable for instantaneous speed measurement, the sampling frequency is 50,000 times per second, the sampling time is as high as 0.02ms once, the maximum instantaneous speed of 300m/s can be measured, and multiple pulses can be output, which can be used in a very short time. It measures the instantaneous speed of a high-speed moving object with a length of only a few centimeters.

For example, cylinder measurement, piston, Hopkinson rod and other instantaneous speed measurement
