lle series description the enhanced series of liquid level sensors incorporates a photo-transistor trigger which provides a digital output that denotes the presence or absence of liquid. the mode of operation is derived from the principle of total internal reflection. an led and photo-transistor are housed within a plastic dome at the head of the device. when no liquid is present, light from the led is internally reflected from the dome to the photo-transistor. when liquid covers the dome, the effective refractive index at the dome-liquid boundary changes, allowing some light from the led to escape. thus the amount of light received by the photo- transistor is reduced and the output switches, indicating the presence of liquid. this method of liquid level sensing is very fast, and almost instantaneous for water. features ? solid state technology small size digital output pre-wired electrically robust typical applications home appliances spa baths vending machines food and beverage medical compressors machine tools automotive liquid level sensors benefits accurate, repeatable switching point can be mounted in applications where space is limited microprocessor compatible easy to install, saving assembly time reverse polarity, over voltage, short circuit and transient protection order guide catalogue listing description standard temperature high temperature (type 1) lle101000 lle101101 screw in, m12 thread, plastic (type 2) LLE102000 lle102101 (type 3) lle103000 lle103101 push in, plastic (type 5) lle105000 lle105100 screw in, ? in, metal nickel plated brass lle205000 lle205100 stainless steel lle305000 lle305100
