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.
A float level switch or liquid level switch is a type of level sensor that has a simple design and usage principle. The float encircles a stationary stem and has magnets contained in the float. When the float rises and lowers, the magnetic field actuates a magnetic reed switch in the stem. This magnetic reading can then accurately identify the liquid level within one eighth of an inch.
