Honeywell LLE Series Liquid Level Switches

The Honeywell LLE Series Liquid Level Switches have a similar design to SST’s liquid level switches. The only difference being the housing where the sensor tip is dome shaped. Used for the detection of liquid level or liquid leaks, and designed to switch digital I/O, LEDs, coil relays, buzzers, and incandescent lamp indicators.

The Honeywell LLE Series liquid level switches use the same operating principle as the SST optical liquid level design, 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.

The Honeywell LLE Series Liquid Level Switches have a broad port folio that covers numerous potential applications including home appliances, food and beverage, vending machines, medical, industrial compressors, HVAC, transportation, aerospace and military.
