PRODUCT DESCRIPTION 2
Self-alignment functionality (only DUSTHUNTER T200)
sender module can be moved horizontally and vertically using motors and bevel gears so
that the sender light beam can be adjusted by approximately 2° in all directions. Tracking
is performed using the measurement signal on the 4 quadrants of the measurement
receiver. This allows automatic compensation of optical axis misalignment caused by, for
example, distortion of duct walls due to temperature fluctuations.
