LV-7200, a new laser in-plane velocimeter that uses eye-safe lasers to detect speed differences with high response and precision. 2-channel detection and differential calculation are possible.

We have developed the LV-7200, the world's first laser in-plane velocometer using an eye-safe laser that outputs the speed difference between two sensors. By simply shining a laser beam on the object, it can measure the rotational speed of a rotating body, the speed of a moving transmission belt, and variations in film transport speed without contact.

Without processing the object, it outputs the speed difference between any two points in a machine system with an accuracy of 3000 ppm (0.3%). This output can be used for speed control in production equipment for lithium-ion batteries and high-performance films, contributing to the reduction of losses in the processing stage. The response frequency is extremely high at 20 kHz, enabling control evaluation and behavior detection for motors that require higher speeds and efficiency.

These measurement technologies, which address the needs for reducing energy and material losses, contribute to building a sustainable society.

Features of the LV-7200 laser in-plane velocometer

• By connecting two sensors using 1.5 μm band laser light, it is possible to directly measure the speed difference between sensors due to slippage.
• With a response frequency of 20 kHz, four times higher than conventional models, it instantly detects even minute changes in speed.
• The analog output accuracy of the detection speed is ±0.3%, making it suitable for analysis and control applications with high precision.
• Thanks to its eye-safe laser design, it can be used safely without the need for special protective equipment or safety glasses.
