Photoelectric level switch LLE series detailed introduction:

Photoelectric level switch LLE series

----Brand: American Hall (Honeywell)


1. Brief introduction of LLE series photoelectric liquid level switch:

        The liquid level sensor can provide a switching signal to detect the presence or absence of liquid. Its working mode is the principle of total internal reflection. There is an LED and detector in the plastic dome of the head of the device. When there is no liquid, all the light from the LED is reflected from the dome cover to the detector. When the liquid covers the dome, the effective refractive index at the dome cover/liquid boundary changes, so that the light emitted by some LEDs escapes, the light received by the voltage level switch decreases, and the presence of the liquid is indicated by the high and low switch signals.


2. Features of LLE series photoelectric liquid level switch:

1. The material of polysulfone mold has strong resistance to various harmful chemicals and pressure;

2. Wide range of measurement media, fast response, high repeatability, accurate liquid level measurement;

3. Low cost, no maintenance required;

4. Easy installation.


3. Application field of LLE series photoelectric liquid level switch:

       Automobile, heavy machinery, railway equipment fuel tank liquid level detection, mechanical processing industry;

       Whether there is lubrication and cutting oil detection, compressor, cooling liquid level sensor, storage tank high and low liquid level (or full, empty) alarm, etc.
