Gems offers the broadest selection of single point liquid level switches anywhere. Our switches are available in a vast range of sizes, mountings and materials and sensing technologies. Gems float-level switches with proven reed switch design offer trouble-free service with precise repeatability. Our electro-optic liquid level sensors are compact with solid-state switching and no moving parts.
Gems ultrasonic liquid level switches are ideal for applications requiring solid-state level measurement such as ultra-pure, dirty, coating, scalding or corrosive type liquids. Our new capacitance level sensors are available in contact and non-contact versions. Gems sensor detects liquid levels non-intrusively from the outside of plastic bottles, virtually eliminating concerns over sensor compatibility, calibration and liquid media contamination.
