Optical detector CRAB

presencelasermonitoring

CRAB is an easy-to-operate, active oil slicks optical detector. The instrument detects the presence of oil films on the water surface using optical sensing with a vertical laser beam and measuring the differences in the reflection properties of water and oil products. CRAB sensor detects any type of oil regardless of its nature, physical characteristics, and chemical content. METHOD Remote optical sensing of water surface with vertical laser beam. PRINCIPLE OF OPERATION Based on the difference in light reflection from water and oil film surface. features and benefits Continuous remote optical sensing, no sampling High sensitivity: detection of oil slicks with thickness down to 0.5 micron Sensitive to oils of any nature (mineral, synthetic, or vegetable) No interference from scattered radiation Low interference from ripples and waves (beam/surface angle up to ±20°) Waterproof housing for outdoor installation Optional heating of the sensor is available upon request Mounting at stationary points, buoys, motor boats Accuracy of detection irrespective of mounting height Long-term operation without maintenance APPLICATIONS Monitoring of water surfaces (sea, harbors, lakes, rivers) Oil leakage detection Monitoring of process and waste waters equipment and options Oil slicks optical detector CRAB Power supply unit for AC 100–240 V power mains (optional)
