Laser Doppler Velocimeter & Length Gauge

Description

Unidirectional Laser Velocity and Length Measuring Instrument

Product Description

Bidirectional Laser Speed & Length Meter is suitable for measuring

the length and speed of objects with various materials, colors, shapes, and

transparency levels, and can also be used for fixed-length cutting. It

supports zero-speed mode and forward/reverse direction detection,

making it ideal for production lines with frequent start-stop operations

and material reversal.

The product supports multiple industrial communication protocols,

including Modbus (RTU/TCP), Bluetooth, as well as industrial Ethernet

protocols such as PROFINET, PROFIBUS, EtherNet/IP, and EtherCAT.

• Non-contact measurement ,no calibration requested
• Measurement accuracy of ±0.05%,repeatability of ± 0.02%
• Can be widely used in industries such as cables, rubber, plastics, paper

making, non-ferrous metals, packaging, film, cold rolling, hot rolling,

cloth, extrusion, etc

• RS485, logic input/output, pulse output, industrial Ethernet. etc.

communication is available for choice

• Provide different installation target distance and optical depth options,

ensuring high accuracy measurement

• Suitable for frequent start and reverse operations while maintaining

measurement accuracy and repeatability.

• Supports bidirectional length measurement, ideal for production lines

with frequent start-stop operations and material reversal.
