Chambered Level Switch

Chambered Level Switch

A chambered level switch is a switch which is enclosed in a casing, or chamber, that surrounds its switch mechanism. Chambered level switches are used to monitor the amount of liquids and various other materials in a variety of containers. They can also be used to control the flow of these materials into and out of their containers.

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 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 5000 psi) as well as extreme temperatures.

Due to the various specifications of these switches, chamber level-style switches are useful in a variety of applications including oil refineries, chemical plants, hydraulic systems and boilers.
