Sensors that detect liquid and air bubbles without fail

Panasonic’s liquid level sensors, available from Digi-Key, are designed to detect the presence of liquid in a clear tubing or can be used to detect bubbles in liquid. These sensors are designed for 2mm, 3mm, and 4mm clear tubing to snap into them for positive detection without debris or mis-alignment issues. Built in amplifiers equipped with two outputs determine if liquid is present or absent. The sensors are perfect for dispensing or empty container applications as well as bubble detection for liquids of all kinds.
