Overview
Characteristics
Operating
Principle
HCC-96RF-C(S) Series is a Radio Frequency Type Level Switch, and it detects level of a
medium by sensing of capacitance value change caused by a dielectric constant of each
medium. HCC-96RF-S Series can solve the build-up phenomenon of the detection part
due to electro-conducting materials by using "Guard Technology Phase Shifting".
For HCC-96RF-C Series, if the level of the medium increases and the main probe comes
into contact with the medium, the impedance changes depending on the capacitance
value. Using phase change of the signal being measured according to change of
impedance, measure the presence or absence of the medium and output it to the relay
contact.
For HCC-96RF-S Series, compares the signal flowing from active sensing probe towards
ground with reference RF signal, when the medium is detecting. Since all material has
unique dielectric constant (relative permittivity) and conductance value that are different
from air, the impedance of the signal circuit is changed when medium touches the
probe. This change causes a shift in phase of the RF Signal. A phase difference between
the active signal and reference signal causes the output circuitry to operate. (This type
can only be applied to solid/dust.)
For cylindrical tank, the capacitance can be obtained as follow.
C : Capacitance of medium (pF)
ε: Relative dielectric constant
L : Length of Probe
D : Outer diameter of tank
d : Outer diameter of sensing probe

Installation
Precautions
for
Installation
- If more than one level switch is installed in a tank, the distance between each probe
shall be at least 300mm apart. (If the distance between probes is short, it may be
affected by the interconnection of the instrument, causing unstable operation.)
- For side mounting installation, an inactive rod shall be located at least 50mm inside of
tank, and it is recommended that the probe be tilted by 15 degrees to the horizontal
surface. (A foreign object between the nozzle and the probe may cause malfunction.)
- Protector shall have sufficient area to protect the sensor from incoming medium and
be installed at a distance that does not affect sensor operation.
- For side mounting installation, the cable entry shall be installed facing the ground to
maintain the waterproof function.
- When installing on the low level, carefully install the dead stock and material bridge.
- For outdoor installation, it is recommended to install the sun cover to avoid the effects
of temperature increases.
- In case of tank with stirrer, the probe shall be installed at a safe distance from the stirrer.
HCC-96RF-C(S) Series is generally used for high or low alarm with an installation on the side or
top of the tank and can be also applied to metallic or synthetic resin tank as there are no
restrictions on the material of the tank.
■Side Mounting Installation
- If the content has the characteristics of creating an excess sediment layer, the
product shall be installed at an angle of about 45 degrees.
- If the content has a high density, a protector shall be installed at least 200mm
above from the probe in order to protect the probe.
■Top Mounting Installation
- If the probe length is more than 1000mm, install a fixed bracket insulated at the bottom.
- Sensing probe shall be installed at least 500mm away from the side of the tank.

for Use
Precautions
for Removal
Precautions
for Grounding
■Do not bend or extend the sensor randomly.
■Make sure to install the product and the cover first before supplying the power.
■Do not use if the temperature range of the installation exceeds -20℃to +60 ℃.
■Do not use if the protection grade requires a higher grade than its product. (IP66 for
AL. Housing or IP65 for PBT Housing)
■Do not use where vibration is present.
■Connect correctly AC(90~240V) or DC(+24V) power to the power specification.
■Make sure to connect the DC power with correct polarity(+, -).
■Do not connect the wire with the power connected.
■It provides DPDT output by default, wired COM and N.O terminals when using the high alarm.
■External grounding shall be completed.
■Check the level and presence of medium in the tank before removing it.
■Wear gloves when removing it, to prevent a burn.
■Disassemble work shall be done with the power off.
■Make sure that any O-ring or gasket is not damaged while opening or closing the
cover of product.
■The grounding has an external and an internal grounding. When connecting to an
external ground, the ground wire shall be 4㎟(4mmSQ).
■The internal grounding wire shall be the same size as the power line, and the size of
the internal grounding terminal lug shall be 3.1㎟(3.1mmSQ). If the power line is
larger than 3.1㎟, connect the ground wire without terminal lug.
Please do not apply high impact to the product.
Make sure to insert a washer if the terminal lug is removed from ground
terminal and then re- connected. (Loosening prevention)
■Connect the flanges or bolts with the same specifications.
■Make sure to insert washers between bolts and nuts to prevent loosening.
■Make sure to insert gaskets between flanges. (Select the gaskets in consideration of
the temperature of the content and the pressure inside the container.)
■Make sure to install the product and the cover before supplying the power.
■When installing the sensor, avoid shaking or obstacle.
■Condensation may occur if the temperature of the housing differs significantly from the
ambient temperature, so dehumidifier shall be filled or ventilated(gortex) before use.
When installing the product, use the tool to tighten it.
