Bins, hoppers and silos
Mounted in bins, hoppers and silos to control level, filling and emptying.
Rotary paddle
Paddle Level Switch
A small motor turns a paddle inside the vessel. When solids build up around it, the motor movement changes and the switch gives the level signal.

Overview
A simple high-level alarm for solids
A small motor turns a paddle inside the vessel. When solids build up around it, the motor movement changes and the switch gives the level signal.
When the material level drops, the loaded tension spring returns the motor to its original position and the unit is reactivated.
Heavy duty, and suitable for level detection of dust, granules and free-flowing solids up to 10 mm.
Vane count to the material
One to four vanes depending upon the specific gravity and particle size of the medium.
Low density capability
Minimum medium specific gravity of 0.04 kg/m³.
Industry proven
Agriculture, chemical and food industries among the common application areas.

The material decides the build
Share the material, bulk density, vessel size, temperature and insertion length. We will select the paddle and mounting arrangement.
- Fluid, specific gravity and concentration
- Flow or level range, and line size
- Operating pressure and temperature
- Material of construction and end connection
- Output, display and area classification
