Rotonivo® - The rotary paddle level switch from UWT operates reliably and maintenance-free and offers a compatible solution for plants for safe level detection in bulk solids.

Depending on the requirements, the Rotonivo® rotary paddle switch is used as a full, demand or empty detector in storage silos or process vessels and is suitable for use in almost all solids. With its simple electromechanical measuring principle it can also be adapted for extreme process conditions.
A motor driven shaft causes the vane to rotate. Once the material level reaches the vane, thereby preventing further rotation, this creates a torque, which is converted via a switch to an electric signal. Once the vane is free again of the material, the output signal is reset and the motor driven shaft rotates again.

This reliable and maintenance-free limit switch for safe level detection in bulk solids has international approvals for use in gas and dust hazardous areas and is also certified to SIL 2.
