Components
Features
■ The level of different types of liquid and power can be detected.
■ It has a solid structure and is semi-permanent, because it does not have any
mechanically moving part.
■ It can be used with a corrosive liquid (aqueous solution).
■ Wiring facilitates installation (HCC-95PW).
■ Operation state can be checked.
■ Different shapes of probes are offered for different purposes.
HCC-95P Series can be installed on the top and side of the tank, and it is a
Capacitance Type Level Switch device that converts, measures and senses the inherent
dielectric constant of the measured object into a capacitance value, and outputs the
water level.
When the level between the electrode probe and wall increases, the air around electrode
probe is replaced with another dielectric substance (object to be measured) to change the
capacitance value. Initially, the electrode probe has a low capacitance value in the air, but the
value increases when the object to be measured rises and covers the electrode probe. This
change is sensed to detect the object to be measured.
C: Capacitance of object to be measured.
C1: Initial capacitance.
R : Conductivity of object to be measured.
