These special thru-beam sensors are used for checking fluid levels and detecting the level of liquids containing water. The particularly strong IR beam of the emitter penetrates not only transparent, but also semitransparent or coloured containers such as PFA packages or shampoo bottles. The sensitivity of the sensor is adjustable, which allows foam to be distinguished from liquid in drinks, for example.
