Density measurement in concrete residual water
The development of the OLAS measuring system, an online measuring system for determining the solids content of concrete recycling water, began almost ten years ago. Today, a reliable and economic measuring system is available that has reached series production maturity. The OLAS is named after its function: ‘Optical Light Absorption Sensor’. The OLAS makes use of a sophisticated infrared absorption measuring method, in which the measurement light is introduced into the medium via optical fibres. If desired, the OLAS can be supplemented by the OLASTPC (OLAS Touch Panel Controller), an optimal evaluation, display and control unit, to form a complete measurement system.

OLAS - Optical Light Absorption Sensor
OLAS - functional principe & specific features The Optical Light Apsorbtion 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 methode 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.
