Point level detection with Rotary paddle switch

Depending on the requirements the rotary paddle level sensors are used as a full, demand or empty detector in storage silos or process vessels and is suitable for use in almost all solids. With their simple electromechanical measuring principle, they can also be adapted to extreme process conditions. The UWT rotary paddle level switches can be used in applications with process temperatures of up to 1100°C and process pressures of up to 10 bar.

The robust and versatile functional principle is based on a motor-driven, rotating measuring blade, which is inhibited in its rotary motion when covered with bulk material. This creates a counter-torque which is converted into the electrical output signal "covered" via a swivel movement at a switch. If the bulk material no longer covers the measuring blade, the switch is reset to its initial position via a spring. The original state is reached again, the output signal is inverted.

FAQs

Which fill level measurement is useful in multi-chamber silos?

With just a few simple programming steps, the UWT lot system also enables content measurement in the lower part of the double-chamber silo. Rotating paddle detectors from the robust Rotonivo RN 3000 series are used as the standard solution for full and empty detection.

Which measurement technology is suitable for statically charged, light bulk materials?

Rotating paddle detectors (e.g. Rotonivo RN 3000) fulfil these requirements. The high quality and complete dust-tightness of the RN 3000 as well as its sensitivity enable precise, customized measurement. These properties predestine the sensor for use in many areas of the synthetic sector. The system is completely independent of the nature of the bulk material to be measured.

Which point level switch is suitable for very light materials such as EPS, EPP or dry blend (bulk density approx. 15g/cm³)?

A rotating paddle detector (e.g. UWT Rotonivo RN 3001) with the rubber paddle specially developed for such applications fulfils this difficult measuring task. Due to the size of the vane and the sensitivity setting on the electronics, EPS and EPP spheres are reliably measured.
