A chambered level switch is a level switch contained inside a sealed chamber housing. These switches are used for applications where the metal components of the switch cannot touch the base material. The switches are used for measuring and controlling the liquid level of different materials, such as in transmission lines and large liquid holding tanks.
There are actually several different customization options for a chambered level switch. Each customization option is best suited to a different application.
Chamber housing: The switch housing comes in two different designs. Sealed housing keeps all of the components of the switch completely sealed off from the base material. No part of the switch touches the actual liquid inside the container. This is ideal for corrosive materials and harsh chemicals, or when sanitation is a priority, such as in food handling. Flanged housing provides additional strength for the switch and keeps it from breaking and attaches to the base wall easier.
Housing type: Usually customers have the option of choosing what kind of housing their want on their switches, such as plastic, carbon, glass, steel, or another hard material. Depending on the usage, certain types of housing are better than others. Plastic housing, for example, would not work well with corrosive chemicals or hot liquids, but could work just fine for non-toxic liquids.
Process connections: Some customers may have different connection needs than others. Chambered switches have the option for several different process connections, such as RF sensors, displacer sensors, or electric sensors.
Accessories: There are a wide range of accessory options for chamber switches, such as additional air filters, temperature extension, fiber tags, conduit reducers, changes in sensor length, and epoxy coatings for enclosures. Customers can choose accessories based on their individual needs and processes.
