Rotary level sensor for cement | flour | bulk materials | 24VDC | IP65

Technical Specifications

Product type: Cement / bulk material level sensor
Operating principle: Rotary paddle (mechanical level switch)
Supply voltage: 24 V DC
Output: Relay (ON / OFF signal)
Installation: Side mounting (into silo, bunker, or tank)
Application purpose: Level detection (material present / absent)
Suitable materials: Cement, dry powders, granules, bulk construction materials
Operating environment: Dusty, vibrating, industrial
Construction: Mechanical, without complex electronics
Maintenance: Minimal required

Functions and Operating Principle

The rotary paddle rotates continuously when the container is empty

When cement or other bulk material reaches the paddle, rotation is stopped

The stop activates a relay signal, transmitted to a PLC, relay, or control system

The system can be used for:

High-level control (overfill protection)

Low-level control (material shortage signal)

No calibration required, no complex settings – operates immediately after installation

Applications

Mixing plant operators: Cement level monitoring, protection against production without material, automated supply control

Electricians: Easy connection to automation circuits, simple relay logic, reliable operation without false signals

Engineers / designers: Reliable solution for silo and bunker level signaling, resistant to dust, vibration, and harsh conditions, suitable for concrete, cement, and construction mix industries

Construction and industrial companies: Concrete plants, dry mix lines, cement storage, bulk material logistics systems

Advantages

Reliable mechanical operating principle

No calibration or complex maintenance required

Direct relay output signal

Suitable for cement and difficult-to-measure bulk materials

Disadvantages

Does not indicate exact level (only present / absent)

Mechanical contact – not suitable for very sticky or wet materials 

Not intended for liquids
