An optical level sensor detects the presence or level of liquids using light-based sensing. It provides non-contact level detection without moving parts, reducing mechanical wear and routine maintenance demand. The sensor emits light and monitors changes in reflection or refraction to determine whether material is present at a set point. This approach suits tanks and…
