OLAS (Optical Light Absorption Sensor)
Absorptiometry and density measurement
This Sensor (OLAS), fabricated by the Werne&Thiel GbR company sends light into the material of interest (medium) and makes use of the accurately measured absorption of light to determine the composition of medium.
By this method not only the composition of water slurries, suspensions and composite materials of all kinds (e.g. cement slurry, chemical pulp, etc.) can be determined, but also the thickness of foils and coatings and much else. Whatever in production, manufacturing or processing results in a change of absorption of light of medium can be measured, monitored and controlled by the OLAS .
