Ray Retro Reflective Optic Level Switch

Ray Retro Reflective Optic Level Switch

Measuring Principle:

• An infrared emitter sends chopped light into the Prism. When in air the light undergoes total internal reflection and is sensed by the Photo-detector.
• When the Prism is covered by the liquid, the light gets dispersed and so is not detected. This change is processed to signal an alarm.

Applications:

• Liquids like: Glucose, Petrol, Diesel, Oil, Fruit Juices, Water, Chemicals, Honey, Aerated Drinks, etc.
• Detection of Liquids in Pipelines
• Overfill and Dry Run Protection
