Save resources in an environmentally friendly way and benefit from cost advantages at the same time with the OLAS sensor, an optical system for online density measurement of residual concrete water. The name OLAS stands for Optical Light Absorption Sensor and the function is based on absorption measurement of infrared light. The IR light transmitted via fibre optic cable penetrates the measurement medium and the light loss due to absorption is evaluated and output as a density signal.
