Overfill Protection for Dry Goods
For dry goods such as grains, sand, pellets, and other granular or powdered materials, membrane switches are often used. These level sensors are specifically designed to monitor and control fill levels in silos, containers, and other storage units handling such materials.
Membrane Switches for Overfill Protection
Membrane switches operate by using a rubber membrane that is affected by the material pressure inside the container. When the material reaches a certain level, the membrane is pressed inward, activating a microswitch, which in turn can control, for example, a valve or pump to stop the filling process.
Our membrane switches are versatile and can be used both as level sensors and overfill protection in various applications such as conveyors, cleaning machines, dryers, and scales.
Functionality and Safety Features
Membrane switches are designed to withstand high material pressure without damaging their internal components. The membrane's movement is limited to around 3–4 mm, minimizing the risk of overload. To handle changes in air pressure inside the switch, our units are equipped with a pressure compensation mechanism, ensuring proper functionality even with pressure variations.
Applications for Our Membrane Switches
- NV 14P for Heavier Granular Materials: This model is specifically designed for heavier granular materials such as grains, seeds, sand, and pellets. It is easily mounted in the container wall and equipped with a flange for recessed mounting in thin-walled containers.
- NV 10P for Conveyors: The NV 10P is a compact version of the NV 14P and is ideal for overflow protection in conveyors. It requires a distinct force to activate the microswitch, making it suitable for situations where precision is crucial.
Installation and Maintenance
Our membrane switches are easy to install and can be mounted both inside and outside containers. It is important to choose the correct model based on the type of material and the specific requirements of the application. Regular inspection and maintenance of the level sensors are recommended to ensure they continue to function optimally.
