Function :

To sense the material jamming in a compact chute in feeding hoppers

Construction :

The RF level switch is working on the COAT GUARD TECHNOLOGIES incorporating DRIVEN SHIELD AND PISTON CAPACITOR circuits, providing a very low impedance coat guard terminal to power a driven shield on the sensing element. This prevents the conductive and non-conductive coating from causing false signal. This makes the system different than the conventional RF Capacitance level switch. The major difference is of COAT GUARD design which is exactly at the same voltage and phase at all the time. This prevents the material build-up causing a false alarm, which otherwise will cause a false alarm in conventional capacitance level measuring system

  Available in top mounting and Side mounting.
  Fail safe logic is field selectable.
  Fast and easy installation. Simple to calibrate.
  Three element coat guard technique ignores the material built up on probe.
  Cast Aluminium, IP-65 Grade, Enclosure suitable for field mounting (Control Unit).
