Series F6 & F7 Horizontal Mount Level Switches are designed to mount through the walls of tanks and other vessels. Series F6 & F7 Specialty Level Switches are designed for unique applications.
Operates automatically to indicate tank level. Perfect for starting or stopping pumps, opening or closing valves, or actuating level alarm signals. A unique magnetically actuated switching design gives superior performance. There are no bellows, springs, or seals to fail. Float arm hinge design limits the arm angle to prevent vertical hang up.
Features a leak proof body and float constructed from tough, durable polyphenylene sulfide which has excellent chemical resistance. Because the liquid level snap switch is magnetically actuated, there is no direct mechanical linkage to leak or fail, assuring longer life and decreased maintenance costs.
Designed and built for years of trouble-free service in a wide variety of process liquid level applications. Operation is simple and dependable with no mechanical linkage as the level switch is magnetically actuated. The float lever pivoted within the body moves when the process liquid displaces the float.
These float switches work like a standard light switch, they open and close contacts to control whether or not signal current can pass through. When they are closed, the current is flowing and when they are open, the current is not flowing. The "normal" state is when the float switch is down, resting on it's cable or float stop. Some float switches have hysteresis built-in which tells the pump not to chatter, but to turn off at one level, and turn on only at another level. The floats have multiple up to four switch points in a single float. Many float switches are simply used for level indication.
