![]() ![]() As the float rises or lowers with liquid level, the magnetic field generated from within the float actuates a hermetically sealed, magnetic reed switch mounted within the stem. Gems 57144 TH-800 Series Temperature Level Switch TH-800 Series Single-Point Level Switches incorporate level monitoring and a temperature switch in a. Ellwood, an employee at Bell Telephone Laboratories, invented the reed switch. This switch is called the magnetic level switch or magnetic float level switch. In most models, a float encircling a stationary stem is equipped with powerful, permanent magnets. The switch float, of course, moved when the liquid changed levels. The switch actuation points remain constant over the life of the unit. Gems Liquid Level Sensors operate on a direct, simple principle. With large float displacement, the LS-1900 Series switch withstands rough service. Because the effects of shock, wear and vibration are minimized, these hermetically sealed switches provide precise repeatability with no more than 1% deviation. LS-1900 Series Single-Point Level Switch are intermediate in size, are suitable for high viscosity liquids and provide excellent stability for general use in oils and water. From there head north and enter the Lost Woods. The durable construction of these reed switch designs ensures long, trouble-free service. Return to Kakariko Village and walk all the way to the northwest corner of the town. Contact Gems with your liquid specifications for further information on this type of application. In addition to tracking changing level points of a single liquid within a tank, "multi-station" level switches are ideal for monitoring liquid interfaces and emulsions in vessels simultaneously containing two or more liquids. Gems Sensors offers a broad range of flow switch configurations for use in liquids or gases that feature high quality, corrosion-resistant materials for use in tough environments with material choices, ranging from stainless steel to Ryton for vast chemical compatibility. Only a single entry point into the tank is required, and all electrical wiring emanates from a single source. These "multi-station" units offer the most practical way to monitor multiple liquid level points within a single tank. Custom length levels can be configured with "up to seven" independent switch actuation levels, depending on the series type. Gems™ custom length level switches are extremely versatile. ![]()
