PRODUCTS: Choosing a Sensor

A range of models of LaserGauge® Sensors are available for specific applications or industries.

LaserGauge® sensors are available for portable, handheld, or assembly line use and take accurate measurements on opaque, transparent, and shiny materials.

What to consider when selecting a sensor

Following are the major considerations faced when selecting a LaserGauge® sensor:

  • Feature(s) to be inspected
  • Nominal value of the feature to be measured, and accuracy requirements (determines Field of View)
  • Handheld or connected to a computer
  • Material that will be measured – solid, non-shiny materials only (red laser) or solid materials, plus, shiny, translucent, and transparent (blue laser)
  • Benefit you are looking to gain over your current inspection tools (faster, data recording, precision, etc.)
  • Budget and timeframe

Choosing between Red or Blue Laser Technology

Selection of Red vs Blue laser technology comes down to a question of the surface material being measured. Red laser technology is used on solid surfaces, such as painted or unpainted, non-shiny surfaces, and is less expensive. Blue laser technology works accurately on all kinds of surfaces including painted, unpainted, translucent, transparent, some plastic, composite, and shiny.
