LLE101000

LLE Series Liquid level sensors DESCRIPTION The enhanced series of liquid level sensors incorporates a the dome to the photo-transistor. When liquid covers the photo-transistor trigger which provides a digital output that dome, the effective refractive index at the dome-liquid denotes the presence or absence of liquid. boundary changes, allowing some light from the LED to 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 escape. Thus the amount of light received by the phototransistor 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.
