LED is used as the light source! It measures length and speed safely and non-contact!
The VLM manufactured by Astec measures the length and speed of the target object without contact. The VLM is equipped with an LED light source. During measurement, the LED illuminates the target object, and the reflected light is received by a CCD sensor. Signal processing is performed by a built-in processor in the VLM, allowing it to output pulse signals. In other words, the VLM gauge head can be used similarly to a rotary encoder. During measurement, the VLM outputs pulse signals, which can be converted into speed and length by a PLC or data logger, allowing them to be applied as control signals to machinery or used for signals for fixed-length cutting. In the steel industry, there is a demand for high-precision non-contact measurement in processes such as skin pass, slitting, and winding, and the VLM can be applied to measure materials such as strip steel, aluminum, copper, and metal foils. In the paper industry, there are applications for continuous measurement of paper in roll-to-roll processes and winding processes, as well as applications for non-contact measurement of paper pulp in headboxes using the VLM. Additionally, there are various applications for glass cloth, carbon fiber composites, films, fibers, and more.

basic information
〇Main Measurement Targets Strip steel, aluminum, copper, metal foil, paper, paper pulp, glass fiber, carbon fiber composites, fiber, pipes, tubes, electric wires, ceramics, conveyor belts, etc. 〇Main Applications Sending length signals to cutting machines for fixed-length cutting Sending speed signals to machines for control signals Monitoring length/speed 〇Good Maintainability The VLM not only allows for accurate measurements but also measures without friction due to its non-contact nature, preventing the sensor from wearing out by contacting the measurement target. The LED light source has a long lifespan, and users can easily replace it. 〇Robust Body / Accurate Measurement The body of the VLM is built robustly as an industrial measuring instrument. It can accurately measure even in environments with mechanical vibrations or low cleanliness levels. This enables its application in various manufacturing sites. 〇Flexible Adaptation to Various Applications The VLM is a standalone measuring instrument. The sensor, light source, signal processing, and power supply are all integrated into the VLM body. With a digital system concept, it can flexibly accommodate various usage methods. Startup and operation are easy.
