It is a sensor to continuously measure a hydrostatic pressure of a

liquid according to the certain height of the liquid column.

Hydrostatic pressure is calculated using the equation given below.

P = ρ x g x h

[P=Hydrostatic Pressure, ρ =Density of Liquid,

g=Gravity of Acceleration, h=Height of Liquid Column]

As seen in above equation, if density of liquid does not change, measured hydrostatic pressure is

detected as an electric signal proportional to the height of liquid column, since the height of

liquid column is only

variable

■ Installation on top or side of tank.

■ Easy installation and maintenance

■ No effect by a conductivity or composition change of medium

■ It is required attention because it is affected by a change of density.

HT-100P Series is a Hydrostatic Pressure Type Level Transmitter installing in top or side of tank

continuously measures the liquid levels in the tank. It measures hydrostatic pressure and converts

it to the current output, DC 4~20mA. It can be widely used in various industries such as PC Tank,

Dam Surge Tank, Sluiceway. River and Wastewater special work.

Precautions

for Installation

■ When the sensor is installed at an extended nozzle or a ling pipe, liquid should not be

crystallized or congealed on the pipe.

■ Sensor should not be installed at the drainage of tank or a place that liquid is flowing.

■ When the sensor is installed at the top of the tank, and material in the tank behaves like

fluid, a guide pipe should be installed.

■ When the sensor is installed at the side of the tank, a valve should be installed between

the nozzle and sensor.

■ Sensor should be installed and used at the open tank atmospheric pressure compensated.

■ When flanges or screws are used for fastening, the size should be the same.

■ The user should place a washer between each bolt and nut to prevent loosening.

■ When fastening flanges to each other, gaskets should be used.

(The gaskets should be selected considering the temperature of the content and the

pressure of the container.)

■ The user should install appropriate products after judging whether the products are to be

used in explosion-proof regions.

Wiring

Failure Check

& Maintenance

■ When wring of power supply, + - should be wired correctly.

■ Power source should be DC +17V ~ +40V

■ Power should be applied after completion of installation and wiring.

■ Product Check

Pressure sensor should be cleaned periodically (every 2 or 3 months) using clean water

so that the pressure sensor should not be plugged by sludge.

■ Failure Check

The level of measured object changes, but the output does not change.

▶ Check the AMP or Pressure Sensor for abnormalities.

▶ Check the capacity of the power supplied.

▶ Check the polarity of the supplied power.

▶ Check that zero, span adjustment is correct.

The output is only slightly changed for the LEVEL change of the measurement.

▶ Check the AMP or Pressure Sensor for abnormalities.

▶ Check that zero, span adjustment is correct.

▶ Check the pressure cell for abnormalities.

No change of level, but output fluctuation is present.

▶ Check the AMP or Pressure Sensor for abnormalities.

▶ Check that the measuring object is fluctuating a lot.

Output indicates full (20mA) of higher regardless of the change of level of the medium.

▶ Check the AMP or Pressure Sensor for abnormalities.

▶ Check that zero, span adjustment is correct.

Safety &

Environment

■ Precautions for Use

- Make sure to connect the product and vessel using required tools for sure.

- Keep the lock key safe and make sure that it is locked.

- Do not apply high impact to the product.

■ Precautions for Wiring

- Wire should be corrected to terminals that correspond to the locations of contact

points (refer to the connection method).

- Wire and supply the power to the device after checking the specifications.

- Entering the incorrect power voltage may cause damage or failure of the machine.

- Pay attention to prevent electric shock.

■ Disposal of Product

- Make sure to separate the amplifier and main unit from housing before disposing the

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.

■ As shown below, connect the external grounding with the wire at 4 ㎟.

■ Check the level and presence of liquid in the tank before removing it.

■ Overheated product may cause burn, so wear gloves to remove it.

■ Remove it with the power disconnected.

■ Make sure that any O-ring or gasket is not damaged while opening or closing the cover.

외부접지 4㎟ (4mmSQ)

Make sure that it is not subject to any high impact when moving.

Make sure to insert a washer if the terminal lug is removed from the

ground terminal and subsequently reconnected. (loosening prevention)
