A chambered level switch is a switch that is enclosed in a casing or chamber that surrounds its switch mechanism. Chambered level switches are used to monitor and in some cases control the level of liquids and various other materials. They are installed in tanks, transmission lines and in a variety of other contexts.

Chambered level switches, like other level switch and sensor varieties, are essential tools in a variety of industries. They are useful in oil refineries, chemical plants, hydraulic systems, boilers and in many other settings. The use of a level switch instead of other level measuring methods like manual testing, especially in cases in which hazardous or sensitive materials are involved, prevents worker exposure and product contamination. For example, in pharmaceutical product ingredient storage and processing, the level of product can be accurately measured by a level switch without the risk of contamination by humans. The same is true in applications in which the level of food or other sensitive consumer goods are stored or processed. Chambered level switches can measure materials much more accurately and effectively than manual methods.
A chambered level switch interprets the level of materials in an enclosed area based on the state of an internal, responsive electrical circuit. Depending on whether the circuit is open or closed, the level switch can provide readings and send signals to control equipment. Chamber level switches use two types of switches to complete an electrical circuit. A sealed snap-action mechanism may be used, or the switch may use mercury to complete the path between two electrodes within the switch. Chamber level switches are constructed to ANSI/ASME industry standards and can be used in a variety of conditions depending on their specific construction. The switches may be flanged or sealed and may also have vent, drain, and isolation valves. They may be hermetically sealed and weatherproof, able to operate in high or low-voltage situations, capable of withstanding harsh conditions such as acidic environments and even made to be vapor and explosion-proof. These switches can also accommodate a variety of pressures internally and externally (from about 150 PSI to 5,000 PSI) as well as extreme temperatures.
