Accurate & dynamic measurement of distance and speed
Excellent performance and reliability; lightweight and stable metal housing
Short high-energy infrared light pulses provide excellent interference immunity
Measurements are fast offering update rates as high as 200 Hz / 2 kHz / 12 kHz
Measurements can be taken through glass windows into sealed containers
Narrow measurement beam with very low divergence provides excellent spatial
resolution
Measurements can be taken to almost any surface regardless of the incident beam
angle or surface characteristics
Measurements are unaffected by the temperature of the material surface and of
temperature gradients in the medium between the sensor and the target surface
