LLE305000 - Silicon Storage Technology (SST)

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.
