Optical liquid level switch Honeywell Sensing and Control

The LL series Liquid Level Sensor uses an optoschmitt trigger which provides a digital output that indicates the presence or absence of liquid. These components require user supplied external circuit protection.

The LLN series Industrial Liquid Level sensors are designed for harsh industrial environments with extremes in temperature, pressure, vibration, and shock. The LLN series are sealed to meet IP67 and have reverse polarity and overvoltage protection. Housed in stainless-steel, the LLN series has long life and is easy to clean. The LLN series terminates using industry standard Quick-connect connectors.
