Limit detection is required in most silos and containers to avoid overfilling or unnecessary downtime. The sensor needs to deal with an assortment of process conditions within a wide range of industries. Contingent upon the necessities, the RotoNivo rotary paddle switch is utilised 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 adjusted for extraordinary 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 dependable 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
The RotoNivo offers a universal voltage power supply, 24 V DC to 220 V AC. It can be connected to the same unit without any alterations being made and with the absence of additional power supply to the unit, for example in very old plants, is completely nullified. This makes it easy for a processing plant to keep one version in stock that can be used in various applications on different parts of the plant. UWT suits the unit to your application, to ensure complete reliability and effectiveness.
