Optomax Digital Range of Liquid Level Switches

SST Sensing Optomax Digital Range of Liquid Level Switches are ideal for restricted space applications requiring a miniature, low-power, and low-cost sensing solution. The microcontroller-based sensor is solid state, incorporating an infrared LED and phototransistor, which are optically coupled by the tip when the sensor is in the air. When the tip is immersed in liquid, the infrared light from the Optomax Digital sensor 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 in the air or small bubbles in a liquid.
