HCC(HPC)-96RF-R Series
HITROL CO., LTD. 3
HCC (HPC)-96RF-R Series is a radio-frequency type level switch that detects the level of the
measured object by detecting the change in capacitance value due to the dielectric constant of
each object. As compensation electrode method is adopted, repetitive operation can be smoothly
operated even if the content is attached to the sensing part due to the humidity around the
sensing part depending on the content itself or the temperature.
HCC-96RF-R 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 tanks, the capacitance can be obtained as shown below.
■Solid structure and long service life
■Applicable to high temperature
■Explosion proof version (HPC Series)
■Good reliability of level detection
■Prevention of malfunction caused by material build-up on the sensor
■Applicable to metallic or synthetic resin tank also

■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 tank.
- If more than one level switch is installed in a container, 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 installations, an inactive rod shall be exposed to the inside of the tank
by at least 50mm, and it is recommended that the probe be tilted by 15 degrees to the
horizontal surface. (A foreign object may cause malfunction between the nozzle and the probe)
- Probe shall be installed to avoid the inlet side of the measuring instrument, and the
protector shall be installed to prevent damage to the probe.
- For side mounting installations, the entrance to the electric wire shall be installed facing
the ground to maintain the waterproof function.
- When installing on the low level, carefully install the dead stock and the material bridge.
- For outdoor installations, 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.

■ Connection of HCC-96RF-R(Sensor) and HLC-96RF-R(Controller)
- Prepare the cable (CVVS 3C) that connects the sensor and combination unit and connect as
shown below. (The distance between HCC-96RF-R and HLC-96RF-R is available up to 500m.)
■ Power Connection
- The power specification of the instrument consists of AC 110V or 220V, which
energizes the sensor power supply.
- Be sure to check the following items before wiring:
Is the specified power voltage used?
Has the CCVS wires been used for the wires between the controller and the amplifier?
Are separate conduits other than power lines used when the controller and amplifier are engaged?
■ Output Connection
- The contact capacity of relay is AC 250V, 5A / DC 30V, 5A, and larger capacity values
require connecting external relay.
■ Initial / General Adjustment
1. Set the Fine variable resistor to 0%.
2. Turn the Coarse variable resistor clockwise 18 times.
3. Slowly rotate the Coarse variable resistor clockwise until the detect LED changes from
yellow to red.
4. Rotate clockwise or counter-clockwise, repeat the detect LED to operate from red to
yellow or from yellow to red 3 times, then set it at the point where the yellow light is on.
5. Moving the Fine variable resistor from 0% to 10% indicates setting at ultra-high
sensitivity (∠c 1pF).
6. From now on, turn the Fine variable resistor to set according to the dielectric ratio of
the measuring instrument.

The life span of key parts depends on user’s environment and can be used optimally
through periodic check. Therefore, regular inspection ensures optimal performance of
product, so take regular inspection and maintenance at least every year. Inspection of the
appearance of the product shall be visually checked to see if there is any damage, and the
attachment of the medium or foreign substances to the sensor will make it worse, so they
shall be removed regularly.
■Inspection of Products
- When cleaning the tank, remove any attachments that attach to the instrument.
- If the measurement is moving fast or stirring, check the probe for mechanical damage
or insulation.
- The water resistance of the probe shall be checked periodically, as the insulation of
the probe may cause errors and malfunctions.
- When measuring highly adhesive material, it is necessary to check whether the
attachment is growing or not, and if there is growth, remove it periodically.
- Check the level and presence of measure object in the tank before removing it.
- Wear gloves when removing it, to prevent a burn.
- Make sure that any O-ring or gasket is not damaged while opening or closing the cover
of product.
- Unlock the lock key before removing the cover. (Ex-proof)
- Disassemble work shall be done with the power off.
- External ground is located on top of cable entry, and the grounding wire to connect
external ground shall be 4㎟(4mmSQ). (Internal ground is connected before shipment.)
- 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.
- Use the cable gland connection or metal pipe line lead-in on the wire inlet, and use a
product with equivalent Ex-proof certificate to connect it with the external line lead-in
method.
- For non-use external wire inlet, use a closed plug that passes safety certificate above
equivalent performance with the product.
Make sure to insert a washer if the terminal lug is removed from the ground
terminal, and then re-connected. (Loosening prevention)
If there is an atmosphere of explosive gas, do not open the cover of the product.
Make sure that it is not subject to any high impact while moving.
Turn off the power of the product for maintenance.
In an explosion area, do not disassemble when power is applied.
