DESCRIPTION

The LL105100 liquid level sensor components incorporate a voltage level switch 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 detector are housed within a plastic dome at the head of the device. When no liquid is present, all light from the LED is totally internally reflected from the dome boundary to the detector. 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 voltage level switch is reduced and the output switches, denoting the presence of liquid. This method of liquid level sensing is very fast, and instantaneous for water. The LL Series is a basic component which requires external circuit protection; this protection is incorporated in the LLE Series.
