Banner Engineering Corp.: Non-contact laser sensor for challenging measurement, quality control inspections

Developed to solve demanding measurement and quality control inspections on materials such as wood, metal, rubber, ceramic and plastic parts. Providing high-precision capabilities, the robust, self-contained laser displacement sensor features a 1024 pixel CMOS linear imager that can achieve up to a 1 micron resolution under nominal conditions.

The linear imager can be used on a wide variety of materials, reflective surfaces and colors, and allows operators to provide continuous non-contact measurements in applications that involve moving processes, stamped and machined parts, and soft or sticky parts.

Features target displacement or thickness measurement with high resolution 4-20 mA or RS-485 serial communication outputs. Two sensors can be configured to self-synchronize for thickness measurements—performing the thickness calculation within the sensors—requiring no external controller for operation. The LH can be used in a network of up to 32 sensors, providing the capability to perform multiple, simultaneous inspections. A narrow laser spot provides easy alignment to the smallest of targets.

Comes equipped with an intuitive Graphical User Interface (GUI), which guides the user through setup and performance monitoring when adjusting the sensor parameters.  After the LH is installed, the GUI provides data acquisition tools to graphically display the current measurements. Parameters such as analog output scaling, averaging, sample size and other advanced features can all be set within the GUI.  All data is displayed in real time and can be saved to a log file, which is useful for troubleshooting the installation.
