Rotary Paddle Level Sensors: What You Need to Know
When it comes to high-, mid- or low-level material detection, rotary paddles are a commonly used point level indicator due to their “workhorse” reliability. They are often used in conjunction with an alarm or light panel to send alerts when a material reaches its desired level within a bin, hopper, silo or tank.
Why is this important? Bin level indicators with rotary paddle technology provide:
- Universal level detection
- Affordable, Low-maintenance, reliable solution
- Functionality in high process temperatures (*for High Temp model only)
- Adjustable sensitivity
- And more
Rotary paddle level sensors can be used for a wide range of industries, and we see them used most often for agriculture, plastics or cement applications where accurate monitoring is a necessary part of everyday operations.

Model RH/RHX Rotary Paddle Accessories
Used for a variety of reasons, rotary paddle accessories make day-to-day operations even easier. The proper choice and use of a paddle and other type of accessory is important to the success of your installation.
- Paddles are the extension of the rotary bin level indicator shaft into the material and this device contacts the material in the bin when present. The density and particle size relate directly to the paddle to be used, along with mounting criteria.
- Folding paddles enable sensor insertion from outside the bin/hopper/silo/vessel
- Couplings provide a method for connecting the rotary unit output shaft to the paddle when a fixed paddle is to be used.
