Rotary Paddle Level Switch for Silo/Tank, Stainless Steel Blade

SUCH rotary paddle level switch provides reliable point-level measurement for bulk solids and powders in bins, silos, and hoppers, operating steadily from -20℃ to 80℃. It offers flexible voltage options of 220V AC, 110V AC, and 24V DC with a standard blade speed of 1 rpm. Using a rotating paddle design that stops when material reaches it, the switch ensures simple and stable level control for handling bulk materials.

Wiring

Note*:

• When mounting the paddle level switch horizontally, it should be installed with a 15°–20° inclination.
• Ensure the junction box opening faces downward, and the cable gland is securely tightened.
• Before powering on, verify that the input voltage is correct.
• The load of the controlled circuit must be compatible with the switch’s contact rating.
• Do not position the rotary paddle switch near bridge breakers or vibration motors.
• Avoid placing the switch close to the material inlet to prevent blade damage or false triggering; if it must be installed near the inlet, add a 2mm-wide protective shield 200mm above the switch.
• For adjustable-shaft models, when assembling on-site, apply anaerobic adhesive to the locking nut of the universal joint before tightening it with a wrench.
• Always follow the safety instruction, disconnect power before opening the cover during installation or maintenance.
• The installation area must be free from toxic gases that could corrode aluminum alloy.
• The medium temperature must not exceed the maximum value indicated on the product nameplate.
• Do not strike the paddle or drive shaft directly during installation.
