Liquid Level Sensor LLC101000 Description
The Honeywell LLE Series liquid level switches have been manufactured by SST Sensing for over ten years.

SST Sensing has manufactured and branded the Honeywell LLE Series liquid level switches for over ten years. Honeywell recently announced their intention to obsolete the LLE series of Standard Temperature Liquid Level Switches.

The Honeywell level switches use the same operating principle as the SST optical liquid level design meaning, SST are able to offer drop-in replacements for the Honeywell sensors at a lower cost.

The only difference with the SST liquid level switches are the housings. The SST design has a conical tip rather than a domed one as this improves the overall reliability of the sensors. All thread sizes and other critical dimensions remain identical.

SST’s liquid level switches are solid state, incorporating an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid.
