Overview of the Microtrak™ 3 TGS Laser Thickness Measurement System

The Microtrak™ 3 TGS is a high-precision laser thickness measuring device engineered for non-contact applications that demand reliable and repeatable results. Utilizing dual laser thickness sensors, this system offers accurate laser thickness measurement across a variety of surfaces and materials.

Whether deployed as a standalone laser thickness gauge or integrated into a larger system using PLCs or PCs, the Microtrak™ 3 TGS provides versatile, industrial-grade measurement performance. It’s ideal for environments requiring laser panel thickness measurement, laser thickness scanning, or laser gauging of rolled goods, sheets, and extrusions.

Each module is equipped with a built-in LCD display and keypad for straightforward setup and data visualization. A USB serial port allows for remote control via laptop, and standard digital I/O or a Modbus® interface supports system integration and control.

Laser Triangulation Principle for Thickness Measurement

At the heart of the Microtrak™ 3 TGS system is the laser triangulation principle enabling high-speed, one-dimensional thickness readings. A laser projects a beam onto the surface of a material, and the reflected light is captured by a CMOS array. This data is then converted into precise distance measurements.

With auto gain control, the system adjusts laser power to suit a wide range of surface types, including metallic, wood, ceramic, black plastics, and steel. Whether you’re monitoring continuous production lines or performing spot checks, this laser thickness measurement sensor delivers consistent results.

Customers select the Microtrak™ TGS laser sensor because it:

Simple to use thickness gauge
  • is a complete standalone thickness measurement system
  • makes a synchronized thickness measurement
  • provides a process control signal when targets are out of specification
