Laser Gauges for Distance Measurement

Typical applications: automated warehouses, mobile carts, and surface measurements.

Single-point measurement

• Laser measurements typically have good repeatability, but the signal linearity is lower.
• The measurement method does not require cabling to the moving object.
• In reflective mirror models, the maximum measuring distance is up to 1200 m
• In models reflecting from natural objects, the maximum is approximately 155 m

Triangulation measurement

• Laser sensors based on triangulation achieve extremely accurate distance measurement results.
• Two sensors operating on the triangulation principle can measure the thickness of an object without contact.
• The output signal is typically a current or voltage signal, but other signal types are also possible.
• Short response times for analog and digital outputs and a small beam diameter at the focal distance are features that expand the usability of laser sensors in demanding applications.
