The AS2100 accurate distance sensor can measure natural targets up to 100m away and Acuity reflective targets up to 500m away with an accuracy of ± 1mm (0.04 in) depending on target reflectance and environmental conditions. The AS2100 is a rugged laser sensor that can accurately measure on difficult targets, including measurements on black surfaces with solar irradiation. The maximum measurement frequency of the AS2100 is 250Hz in optimal conditions. It is the perfect laser for a wide range of applications including measuring of cranes positioning, trolleys & vertical lift positioning, flood gate position; silo level measurements & controlling the filling and pouring of steel and iron; measuring the length of lumber, pipe, bricks, and other targets; measuring the position of hot metal targets, such as steel & aluminium; and much more.
