1-1 Purpose
1. Product Overview
p
HCC-95P is a capacitance type level switch that detects a measure object by
measuring the change of capacitance value generated from the measure object
(liquid or power) in Tank.
HCC-95P can be installed on the side or top of the Tank in various styles and warns
the upper or lower limit of the level
the upper or lower limit of the level.
1-2 Features
- It can detect the level of various measure objects (liquid or power).
- It has a strong structure and is semi-permanent because there’re no mechanically
running parts.
- It can be used for high temperature and high pressure containers.
- It can be used for containers that agitators are attached.
- It can be used for high or low viscous liquid and highly corrosive liquid.
- Its operation status can be checked on the spot.
- Installation and operation is very easy.
- It can set delay time of Relay contact output.
- There’re various Probes depending on the use.
- Posssible explosion proof
The impedance between Probe and the wall of Tank (i.e. capacitance and conductance)
2. Operation principle and product composition
is changed when Probe, attached to the Tank or a general container, contacts a
measure object.
It converts the changes of impedance to electric signals, run output Relay, and
detects the existence or the level of the measure object.
The following explains how to get the capacitance when the Tank is a cylinder shape.
