Capacitive level switch ( RF Admitance )

CAPACITIVE LEVEL SWITCH 300

Applications
Orion Capacitive is used to display (detect) levels of all kinds of powder and bulk solids material in any type of container or silos. It is a capacitive level switch with adjustable detection sensitivity.

Selection for application area

  • In construction industry for leveling of gypsum, lime, fine sand, dolomite, calcite, perlite, gypsum, cement, stone, coal, pulverized coal powder, etc.
  • In food industry for leveling of feed, seed, flour, salt, sugar, etc.

Functions
When the capacitive sensing type level switch’s probe which is located at the buttom of the instrument is sorrounded by the bulk solid material, there will be a decrease in emitted rf power. An output signal is generated when the amount of reduction is higher than the sensitivity setting. Detection sensitivity can be set up for all kind material depending on type and dielectric constant.
