8D025W11PN Application Field and Working Principle

The 8D025W11PN is a size 8 shell type point-level switch designed to detect the presence and/or absence of high-level liquids in small vessels or tanks, delivering both reliable performance and flexible installation options.

The 8D025W11PN switch consists of a stem that extends down from the top of the tank into the liquid. It is connected to two encapsulated electronic circuits. The lower circuit is submerged in the liquid; the upper circuit is outside the tank. When the stem is lowered to the liquid level, the lower circuit makes contact with two probes causing the switch to close the electrical circuit. The upper circuit is the same as the lower circuit except, it is not exposed to liquid. It is used to open the switch when the stem is raised above the liquid level.

The 8D025W11PN switch is ideal for use in a variety of applications including water treatment plants, chemical manufacturing plants, fertilizer plants, pasteurizing facilities, and in monitoring systems such as liquid flow and level control. Because it is designed for use in liquids that are subject to foaming, it is an excellent choice for applications such as sewage, wastewater, and food processing.

The 8D025W11PN switch works by the principle of electrical capacitance. When a liquid fills the tank or vessel and makes contact with the lower circuit, the reactive electrical fields of the liquid and the probes interact and cause an electrical current to flow. When this current reaches a set point, the switch is triggered and a signal is sent to a controller or system to indicate that the liquid level has reached its maximum or minimum desired point.

The 8D025W11PN switch is very versatile and can be used in a wide variety of applications. It is designed to be robust and are engineered to withstand the rigors of repeated on/off cycles. They are constructed of durable materials and are highly resistant to corrosion and vibration. The switch is also simple to install and can be easily integrated into existing systems or used in new systems.

The 8D025W11PN switch is a reliable and highly reliable point-level switch for a variety of liquid detection applications. It is easy to install and operate, making it a convenient and cost-effective solution for any liquid level detection need.
