LSV-300 System - Features

The LSV-300 System Components

The LSV-I-300 Sensor Head is the watchful eye of the system, measuring the in-plane movement of the material surface with the aid of Laser
Doppler Velocimetry. Its compact size and long standoff distance (500 mm or 900 mm) allows for simple integration into the Production line. Optional housings that cool and protect the LSV enable its use in hot and contaminated environments.

The robust, IP 66 protected LSV Signal Processor powers the sensor head and provides signal conditioning and processing. It accepts commands from process controllers and can be monitored by a notebook computer via its serial interface. The LSV controller easily integrates with a local area network (LAN) through the optional Ethernet interface. Length and velocity data is simultaneously displayed and updated every millisecond at each output.

The user-friendly LSV PC software is an integral part of every LSV measurement system. The LSV PC software runs under Windows® 2000 and XP. It not only simplifies configuring the LSV system, but also offers excellent process, observation and analysis options.

Compact, Reliable, Rugged and Precise


Polytec’s Industrial Laser Surface Velocimeters (LSV) are specifically designed for non-contact, online measurement, inspection and control of velocity and length in continuous process industries such as steel, metals, paper, plastic, glass and building materials. The instruments are easy to install, setup and integrate into control systems and are an essential step to reducing scrap, increasing uptime and improving material throughput. The LSV directly replaces traditional, high-maintenance, problematic contact measurement techniques with accurate, low-maintenance, next-generation, non-contact laser technology.
