■Various probe types for wide application
■Easy installation of wire type. (HT-100CTW-2 Series)

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.

When installing the product, verify the size of the product insert and the
size of the nozzle in the tank before installing the product to the applicable
standards. (ex. Ground tube, Ground Sensor, Weight, etc.)
Installation
Precautions
for
Installation
The capacitance type level transmitter can be installed in screw (PT, NPT, PF) and flange
(ANSI, JIS, DIN) as well as tri-clamp and other various locations.
It shall be used after setting the range at the site according to the site installation conditions
and medium to be measured.
If setting with the other medium which is not actual medium to be measured the measure
value may be not correct.
Pay attention to the following matters during installation.
■Product shall be installed at the place far from inlet in order to avoid the malfunction. (a)
■Protection tube shall be applied if there is a flow or slopping of the medium of the tank. (b)
■Probe shall be installed within Max. 300mm from the tank wall (f), and ground tube type
shall be applied if the distance between the tank wall and sensing probe is far.
■If the tank material is non-conductive(ex. FRP), the rod probe with ground tube type shall
be applied. (c)
■Ground rod type shall be used for corrosive liquid. (d)
■Bracket insulated to a sensing probe shall be installed at the bottom of probe in order to
fix it if the probe length is long or there is slopping of medium in the tank. (e)

■Metal Tanks (Conductive tank)
When installing on a conductive tank, the transmitter housing and tank shall be grounded
as shown below.
되어야 합니다.
■Non-metal tanks (Non-conductive tank)
When installed on a non-conductive tank, use the ground tube (rod) or ground wire type.
Also, the transmitter housing and tank shall be grounded as shown below.

Wiring
Failure Check
& Maintenance
- Make sure to connect the power with correct polarity (+, -), and the power
supply shall be between +17V ~ 40V.
- Do not connect the wire with the power connected.
For Ex-proof product, the cover shall be locked and power shall be
applied after wiring.
■Maintenance
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
