High reliability Explosion Proof Rotary Paddle Level Switch tank level sensor

The purpose of the rotary paddle level switch is to detect the presence of solid/powdery material in most kinds of tanks, bins and containers. The unit is usually located through a bin wall at the top, middle or low level of a bin. During normal operation (no material present) a synchronous motor rotates the paddle at RPM. When this paddle rotation is impeded by material, surrounding the paddle, motor will stall and cause the Micro-switch to change state (indicating an alarm or control).

• Airtight sealing device, outdoor application is available.
• Unique sealing ring design, it can perform good dust protection to avoid the dust permeate into housing body along with the shaft.
• The torque force is adjustable.
• The performance of torsion is stable and reliable.
• If the rotary paddle bears an extra overload, the motor will be appeared slide to prevent the inside mechanism damaged.
• It is rationally designed, the inside mechanisms are easily tore down for checking, maintenance and replacement. It doesn"t necessary to remove the complete set from the tank.
• Very suitable for small tank and material of low density.

• Plastics and synthetics
• Chemicals and fertilizer
• Pharmaceuticals
• Food and beverage,
• Agriculture and fodder mills/depots
• Cement as well as ceramics
• Power plants
