SEN Rotary Paddle Level Switch

Description

SEN Rotary Paddle Level Switch, a robust and reliable solution for level control of solid materials across a wide range of industrial applications. This device is engineered for precision and durability, offering an efficient way to monitor and manage bulk solids, including powders, granules, and gelatinous substances.

The ISEN Rotary Paddle Level Switch is designed with good sealing capabilities and a strong overload capacity. It is lightweight, easy to install, and features a large output contact capacity. A key advantage of this switch is its adaptability to materials with different specific gravities, which can be achieved by adjusting the spring tension. Furthermore, all parts that come into contact with the material are constructed from stainless steel, ensuring longevity and resistance to corrosion.

Key Features of the ISEN Rotary Paddle Level Switch:

• Reliable Operation: Incorporates American small hopper professional technology and features three bearing support for enhanced operational reliability.
• Dust Infiltration Prevention: An original sealing design effectively prevents dust from entering the mechanism (patented).
• Adjustable and Stable Torque: Offers stable and reliable torque, which can also be adjusted to suit various material types.
• Motor Protection: In the event of excessive load on the blade, an automatic clutch slipping mechanism protects the motor from damage.
• Ease of Maintenance: Features an electromechanical separated structure, allowing for easy maintenance without complete disassembly.
• Outdoor Suitability: The junction box boasts an IP65 protection level, ensuring good sealing and suitability for outdoor installations.
• Low-Density Material Compatibility: Special blades are available for use with low-density materials.

Working Principle

The operational mechanism of the ISEN Rotary Paddle Level Switch is straightforward yet effective. A motor drives the blade, causing it to rotate. When the level of the measured medium reaches the blade, the blade’s rotation is obstructed. This blockage triggers a micro switch, which then outputs a switching signal. Conversely, when the material level drops below the blade, the blade is released. Under the action of a spring, it returns to its original position and resumes rotation. The tension of this spring is adjustable to accommodate the specific gravity of the material being measured. For materials with a higher specific gravity, the spring should be adjusted to its strongest setting, while for lighter materials, it should be set to the weakest.
