L-GAGE LH Series

Overview

High speed, high precision, non-contact laser measurement sensor which provides accurate and stable displacement or thickness measurement on wood, metal, rubber, ceramic, and plastic parts.

  • Extremely accurate, robust and self-contained laser displacement sensor using a 1024 pixel CMOS linear imager
  • Precise narrow laser spot for easy alignment to the target
  • Reliable and accurate measurement results on real world targets, such as machined metal, wood, ceramic, paper and painted targets
  • Target displacement or target thickness measurement with high resolution 4-20 mA or RS-485 serial communication outputs
  • Non-contact measurement for use on moving processes, hot parts, machined parts, and soft or sticky parts
  • Two sensors self-synchronize for thickness measurements and thickness calculation within the sensors; no external controller required
