Emas SKF-20 Float Switch with 20m Cable

The Emas SKF-20 is a high-quality float switch engineered for the precise automatic control of liquid levels in tanks, reservoirs, and cisterns. Equipped with a robust 20-meter cable, this device offers extensive reach for installations where the control unit is located at a significant distance from the fluid source. It functions by tilting as the liquid level rises or falls, effectively triggering electrical circuits to start or stop pumps or activate alarm systems, thereby preventing overflow or dry running conditions.

Advantages

This float switch is constructed from durable, corrosion-resistant materials that ensure long-term reliability even in demanding environments. The generous 20-meter cable length provides exceptional flexibility during installation, eliminating the need for complex wiring extensions in large-scale water management systems. Its simple mechanical design minimizes the risk of electronic failure, offering a dependable solution for maintaining optimal fluid levels without constant manual oversight.

Suitable for

• Automatic control of submersible pumps
• Monitoring water levels in domestic storage tanks
• Industrial reservoir level management
• Activation of high or low-level alarm systems
• Drainage and filling applications

When it may not be suitable

This device is not intended for use with highly aggressive chemicals, solvents, or liquids with extreme temperatures that exceed the material's thermal rating. It is also not suitable for applications involving high-pressure environments or fluids with high concentrations of solid debris that could obstruct the movement of the float.

Key specifications

• Cable length: 20 meters
• Switching mechanism: Mechanical tilt
• Application: Liquid level control
• Compatibility: Suitable for various water-based fluids

How to use

Installation involves securing the float switch at the desired height within the tank using the provided cable. The cable should be fixed to a stable point to define the switching range. Once positioned, the electrical leads are connected to the pump motor or control panel according to the required logic, such as normally open or normally closed operation. Ensure that the cable has enough slack to allow the float to move freely through its full range of motion without being restricted by the tank walls or other internal components.

What to consider before purchase

• Verify the chemical compatibility of the float material with your specific liquid
• Ensure the cable length is sufficient for your tank depth and distance to the control panel
• Check the electrical load requirements of your pump to ensure compatibility with the switch rating
• Confirm the operating temperature range of the environment

Usage recommendations

Regularly inspect the float switch and cable for any signs of physical damage or debris accumulation to ensure consistent performance and prevent potential malfunctions in your liquid management system.
