Paddle Level Switches for Dry Materials
Horizontal Side Mount |
Vertical Top Mount |
Monitor the level of dry material in surge bins, tanks, and silos to avoid overspills and outages. With a long paddle, these switches extend farther into large storage containers to detect material levels where other types of switches can’t reach. You can even adjust the paddle's sensitivity to materials of different sizes and shapes, such as powders, plastic pellets, and wood chips. Install multiple switches on the same container to monitor levels at various points. They are rated NEMA 4X and IP66 for protection from corrosion and washdowns.
Horizontal Mount—Commonly installed near the bottom of containers to indicate low levels as material flows out. These switches start to rotate when material falls low enough to uncover the paddle, triggering a conveyor, pump, or other piece of equipment to prevent the container from emptying.
Vertical Mount—Mount to the roof of containers to indicate high levels when loading material. For domed roofs, you can extend these switches farther down by connecting the paddle to your desired length of 1/8 NPT Schedule 40 pipe. The paddle rotates freely until material rises to its level and stops it, triggering a conveyor, pump, or other piece of equipment to prevent overfilling.
LED Alarm Status Indicator—Switches with LED indicators alert you to potential malfunctions before they occur. They continuously perform self-diagnostics to detect everything from motor failure to seized bearings. When they detect an error, the LEDs flash in a corresponding code, so maintenance workers will immediately know which problem they need to fix.
