Product Description
The ISEN-30AAF-1000 is an electromechanical rotary paddle level sensor designed to monitor high-level and low-level conditions in silos, hoppers, and bulk material storage tanks. The sensor operates using a rotating paddle mechanism that detects the presence of bulk material and transmits a level signal to the control system.
Featuring a vertical flanged mounting design, an adjustable shaft length from 650 to 1000 mm, and an SS304 stainless steel paddle, the ISEN-30AAF-1000 is ideal for applications requiring deeper installation than standard rotary paddle level sensors.
Key Features
Adjustable Shaft Length
The shaft length can be adjusted from 650 mm to 1000 mm, providing installation flexibility for large silos and deep hoppers.
Industrial Flanged Connection
The JIS 2-1/2″ × 5 kg/cm² flanged connection ensures secure mounting on the top or side of silos for reliable industrial operation.
SS304 Stainless Steel Paddle
The paddle is manufactured from SS304 stainless steel and measures 100 × 30 mm (W × H), providing excellent mechanical strength and corrosion resistance.
SPDT Output Contact
The SPDT 220 VAC / 10 A output contact allows direct integration with PLCs, intermediate relays, level alarms, and industrial automation systems.
Reliable Operation in Dusty Environments
With an IP65 protection rating, the sensor is suitable for dusty industrial applications such as cement, limestone powder, animal feed, and granular bulk materials.

Operating Principle
The sensor uses an internal motor to rotate the paddle at a low speed. When bulk material reaches the paddle, the resistance created by the material prevents the paddle from rotating, causing the internal microswitch to change state.
The SPDT output signal is then transmitted to a PLC or control panel to activate alarms, stop material feeding, or perform other automated control functions.
When the material level falls below the paddle, the paddle resumes rotation and the sensor automatically returns to its normal operating state.
Applications
The ISEN-30AAF-1000 Rotary Paddle Level Sensor is widely used in:
- Cement silos
- Concrete batching plants
- Animal feed manufacturing
- Plastic processing plants
