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' new XLS-1, an Ultrasonic Level Sensor, is an ideal compliment to the existing CAP-300 in that it has a similar design footprint, but can detect oil, while the CAP-300 cannot. The XLS-1 can also detect many other harsh chemicals, while ignoring foam and condensation.
