Eaton Tedeco Liquid Level Sensors

The Tedeco LevelPro is a self contained, solid-state liquid sensor. It works by the refraction of light from an internal L.E.D. through the liquid being sensed -using no moving parts. Operation is virtually independent of liquid color, viscosity, dielectric constant. conductivity, contamination, foaming, vapor or ice. Hermetically sealed and inde­pendent of mounting position; up, down, angular; electrical parts are not in contact with the liquid.
