HT (HPC)-100CT-2 Series is a Capacitance Type Level Transmitter which continuously
measures liquid levels using of liquid’s dielectric constant. It can be easily installed and
adjusted, and can be easily applied to corrosive liquids and widely used in general
industries, chemical and oil plants.
When there are two conductors insulated each other, the value of capacitance formed
between two conductors is a function of the sizes of two conductors, relative location of two
conductors and the dielectric constant of material placed between two conductors. Under the
conduction that air of dielectric ε₁ exists in the space between two concentric conductors,
lower part of space between two conductors is filled material of dielectric constant ε₂ as
shown below, the change of capacitance is expressed as follows.
ΔC =
Since is a constant value as an initial condition, and get this value
as K, ΔCbecomes a function of level of material only. Therefore, level can be obtained
through the measurement of ΔC.

Failure Check
& Maintenance
Precautions
For Removal
■Check the level and presence of medium in the tank before removing it.
■Wear gloves when removing it, to prevent a burn.
■If there is explosive gas atmosphere, do not open the cover.
■Disassemble work shall be done with the power off.
■Make sure than any O-ring or gasket is not damaged while opening or closing the cover of product.
■Product Check
The major parts of the HT (HPC)-100CT-2 Series level transmitters to be inspected are
divided into the sensor element and the transmission element. The life spans of major
parts vary with user environments and can be used in optimum conditions through
periodic inspections. Therefore, the user shall maintain and repair the product through
periodic inspections conducted at least once a year. In addition, check for the exterior of
the product like visual damage. If the medium or foreign substance is attached to the
probe, it will cause bad accuracy, so it shall be removed regularly. Be careful not to
damage the Teflon part during removal.
■Failure Check
The level of measured object changes, but the output does not change.
▶Insufficient power supply
▶Wrong adjustment of ZERO and SPAN
Only a slight change of output to the change of level of medium is present.
▶Wrong adjustment of ZERO and SPAN
▶A slight change of probe ΔC value
No change of level, but output fluctuation is present.
▶Wrong grounding
▶Noise on the lines
▶Extreme fluctuation of medium
▶Bad insulation of probe
Output indicates full (20mA) of higher regardless of the change of level of the medium.
▶Wrong adjustment of ZERO and SPAN

products. Also, the amplifier shall be detached and discard the metal and non-metallic
materials. No part (ex. Mercury switch) has influence on the environment, so no special
attention is required.
■Pay special attention to prevent any impact on the device during transportation or assembly.
■Pay attention to prevent any damage to any packing when transporting or mounting
the machine to the vessel.
■Use the same standard flange or screw.
■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 temperature of content and pressure of vessel.)
■Install an Ex-proof product only in an Ex-proof zone.
■After the installation is complete and the cover of the product is assembled, power it on.
Please do not apply high impact to the product.
■When connecting to an external ground, the ground wire shall be 4㎟(4mmSQ).
Make sure to insert a washer if the terminal lug is removed from ground terminal and
then re-connected. (Loosening prevention)

■Product Identification
- The product identification mark is attached onto the housing and shows the model
name, serial number, working temperature, working pressure, and matters regarding
output. The serial number is a unique manufacturing number for the identification of
products.
The fluid temperature of the container shall be up to 80℃for Weather-proof type. For
high temperature, the fluid temperature shall not exceed 150℃. In addition, make sure
that the ambient temperature of housing is kept at -20℃~ +60℃.
An Ex-proof product is pressure-resistant and Ex-proof type, so never open the cover
during operation.
Do not apply the Non Ex-proof product in an Ex-proof zone.
