Principle &
Composition
HCC-95P(-Ex) Series is a capacitance type level switch and it detects a level of medium
by sensing of capacitance value change by dielectric constant of each medium.
Where an air surrounding the electrode probe is replaced by other medium, the
capacitance value is changed according to the dielectric constant of the medium. Once
the electrode probe is touched by the medium, the capacitance value is increased and
the level switch activates relay output by converting of the changed capacitance value to
the electronic signal.
C: Capacitance of Medium
C1: Capacitance of Initial State
R : Conductivity of Medium
