61F-11NH

The 61F-11NH is a float type level switch with proven reliability and performance for a variety of level control applications. It is suitable for use in a wide range of fluids including water, oil, and chemicals. The 61F-11NH is a reliable and economical solution for level detection and control in commercial, residential, and industrial applications.

Application Field

The 61F-11NH can be used in various applications including water treatment, pressure control, overflow protection, and boiler level control. It can also be used in process tanks to monitor the level of water, oil, acids, or solvents. It is also suitable for use in sump and sewage pump applications.

Working Principle

The 61F-11NH utilizes a float switch that locates the level of liquid inside a tank. The float consists of two parts: an inner float with a plain stem, and an outer float with a stem that is connected to a reed switch. When the level of the liquid rises, the inner float is automatically lifted and moves the magnet of the reed switch. This action closes the contacts of the reed switch, thus activating the electrical circuit. When the level of the liquid drops, the magnet moves away from the reed switch and the contacts open, breaking the circuit. The switch can be adjusted for either single level or multi-level applications.

The 61F-11NH is constructed from durable materials that can withstand chemical and corrosive environments. The float switch will continue to operate in most liquids, even if the liquid contains suspended particles, such as dirt and sand. It is a reliable and cost-effective solution for accurate level detection and control.
