Reliable point level detection for powders and bulk solids in silos, bins, and hoppers
Instrava rotary paddle level switch is designed for stable and reliable point level detection in powder and bulk solid applications where dust, material density variation, and continuous operation are common challenges.
By combining adjustable torque detection, industrial-grade motor protection, and robust sealing design, this solution minimizes false alarms, reduces maintenance frequency, and protects equipment during material blockage or overload conditions. It is widely used in silos, hoppers, bins, and bulk material handling systems across multiple industries.
Key reasons engineers and procurement teams choose this solution:
Stable and adjustable torque to match different material densities
Built-in overload protection to prevent motor damage
Reliable operation in dusty and harsh industrial environments
Large output contact capacity for direct control system integration
Designed for long-term, low-maintenance industrial operation
OEM / ODM configuration available for equipment manufacturers
A proven level control solution focused on lifecycle reliability rather than short-term cost.
Liquid Level Switches Description
Rotary Paddle Level Switch Key Technology & Performance
Engineering & Technical Selection
Prinsip Pengukuran
The rotary paddle level switch detects material presence by monitoring paddle rotation. When bulk material blocks the rotating blade, torque increases and triggers a switching signal.
Torque Stability & Sensitivity
Stable and adjustable torque ensures consistent switching
Sensitivity can be fine-tuned via spring tension to match material density
Special paddle designs support low-density bulk materials
Motor Protection & Reliability
Built-in overload protection prevents motor damage
Low rotating speed (1 rpm) minimizes wear and extends service life
Output & Integration
Dual DPDT output supports flexible control logic
Suitable for direct integration with PLCs and industrial control panels
Rotary Paddle Level Switch Applications & Industry Solutions
Cement, Minerals & Building Materials
Used in silos and bins for level detection of cement, lime, sand, and aggregates to prevent overfill and material shortage.
Grain, Feed & Agricultural Storage
Reliable level monitoring for grain bins and feed silos where dust and variable bulk density are common.
Chemical & Plastic Processing
Applied for powders and pellets in reactors, storage hoppers, and conveying systems.
Power, Energy & Environmental Systems
Used in ash handling, dust collection, and bulk material storage applications.
OEM Equipment Integration
Widely integrated into packaged silos, conveyors, and bulk handling equipment as a standard level switch.

What applications are rotary paddle level switches used for?
Rotary paddle level switches are commonly used for point level detection of powders and bulk solids in silos, bins, hoppers, and bulk material handling systems.
How does a rotary paddle level switch work?
The switch detects material presence by monitoring the rotation of a paddle. When bulk material blocks the blade, torque increases and triggers a switching signal.
Can a rotary paddle level switch handle different material densities?
Yes. The torque sensitivity can be adjusted to match different bulk material densities, allowing stable operation across a wide range of powders and particles.
Is this rotary paddle level switch suitable for dusty industrial environments?
Yes. The switch features good sealing performance and is designed for reliable operation in dusty and harsh industrial conditions.
What protection features are included to prevent motor damage?
The rotary paddle level switch includes built-in overload protection to prevent motor damage when material blockage or abnormal load occurs.
Is this rotary paddle level switch suitable for OEM and equipment integration?
Yes. Instrava provides engineering support, customization options, and OEM/ODM services for integration into bulk material handling equipment.
