SE Series Rotary Paddle Level Switch

Introduction – SE Series Rotary Paddle Level Switch

The SE Series Rotary Paddle Level Switch is designed for reliable detection of solid and powder materials in bins, hoppers, silos, and other storage vessels. Using a simple and proven mechanical operating principle, it provides accurate point-level monitoring for a wide range of bulk materials. During normal, no-material conditions, a synchronous motor rotates the paddle at approximately 1 RPM. When material surrounds and restricts paddle movement, the motor stalls and triggers the internal micro-switch, providing a dependable alarm or control signal.

Engineered for durability, the SE Series features a robust sealing system that prevents dust penetration along the shaft, ensuring stable performance even in dusty industrial environments. Adjustable torque capability improves compatibility with low-density materials, and optional extendible shafts and multiple paddle designs allow customization to match application requirements. These qualities make it a preferred solution for industrial facilities seeking dependable point-level monitoring.

The SE Series is suitable for various industries such as food and beverage, plastics, pharmaceuticals, agriculture, cement, power plants, and more. Its versatility aligns well with the needs of facilities across the UAE and MENA region, where bulk material storage is common. As a reliable industrial solution, it is supported locally through Dubai Sensor, ensuring availability and technical guidance.

This rotary paddle switch helps reduce downtime, prevent overfill, and maintain process safety. It is ideal for engineers, plant operators, and procurement teams looking for a simple yet robust mechanism for solids level detection.

Installation, Commissioning & Maintenance

The SE Series is installed through the wall of a tank or bin at the desired detection point (top, middle, or low level). After mounting, the paddle is positioned inside the container to rotate freely. Torque can be adjusted to match the material’s density for optimal sensitivity. During commissioning, operators verify paddle rotation in an empty condition and confirm micro-switch activation when material contacts the paddle.

Routine maintenance includes ensuring the sealing ring remains intact to prevent dust ingress and verifying that the paddle rotates unobstructed when the vessel is empty. Overload protection built into the motor helps extend service life and reduce the need for repairs.

FAQ – SE Series Rotary Paddle Level Switch

Q1: What materials can the SE Series Rotary Paddle Level Switch detect?
The switch detects solid and powdery bulk materials, including low-density solids, across industries such as plastics, chemicals, pharmaceuticals, food, agriculture, cement, and power.

Q2: How does the SE Series detect material presence?
A synchronous motor rotates the paddle at about 1 RPM. When material surrounds the paddle and restricts rotation, the motor stalls and triggers the internal micro-switch to signal material presence.

Q3: Can the switch be installed at different levels in a bin or tank?
Yes. It can be installed at the top, middle, or low level of a tank or bin depending on the desired detection point.

Q4: What protects the switch from dust intrusion?
A rugged sealing ring prevents dust from entering the housing along the shaft, ensuring stable performance in dusty environments.

Q5: Is the torque adjustable?
Yes. The SE Series includes adjustable torque, allowing better compatibility with low-density materials.

Q6: What happens if the paddle becomes overloaded?
If overloading occurs, the motor automatically shuts down to prevent internal damage and extend motor life.

Q7: Are different paddle designs available?
Yes. A wide variety of paddle types are available to suit different material characteristics and densities.

Q8: Are extendible shaft models available?
Yes. The SE Series offers adjustable and extendible shaft options for installations that require longer reach.
