Overview

Mechanism

and

Components

Features

■ The level of different types of liquid and power can be detected.

■ It has a solid structure and is semi-permanent, because it does not have any

mechanically moving part.

■ It can be used with a corrosive liquid (aqueous solution).

■ Wiring facilitates installation (HCC-95PW).

■ Operation state can be checked.

■ Different shapes of probes are offered for different purposes.

HCC-95P Series can be installed on the top and side of the tank, and it is a

Capacitance Type Level Switch device that converts, measures and senses the inherent

dielectric constant of the measured object into a capacitance value, and outputs the

water level.

When the level between the electrode probe and wall increases, the air around electrode

probe is replaced with another dielectric substance (object to be measured) to change the

capacitance value. Initially, the electrode probe has a low capacitance value in the air, but the

value increases when the object to be measured rises and covers the electrode probe. This

change is sensed to detect the object to be measured.

C: Capacitance of object to be measured.

C1: Initial capacitance.

R : Conductivity of object to be measured.

Installation

Attachment

and

Cautions

A capacitive level switch can be attached using screws (PT, NPT, PF), flanges (ANSI, JIS, DIN),

or Tri-Clamp. Pay attention to the following for installation.

Installation on the side of a tank (horizontal)

As level is detected with an entire electrode, very sensitive measurement is available.

However, build-up causes malfunction. As such, the electrode needs to be installed at a slant

with its tip horizontally at the bottom.

Installation on top of a tank (vertical)

This installation reduces the effect of build-up, but level is detected only with the tip of an

electrode. As such, it has relatively lower sensitivity and may thus be inadequate for an object

to be measured with low dielectric constant.

■ To install 2 or more level switches in one container, keep 300m or more between probes.

(If the gap is smaller between probes, they may interfere each other causing instability.)

■ For the side installation, the inactive road must be exposed by 50mm or more in the tank

with the probe slanted by 15° to the horizontal plane. (Foreign substance between a nozzle

and probe may cause malfunction.)

■ Keep the probe away from the inlet of measure object, and install a protector to protect

the probe.

■ Keep the wire inlet facing the ground to maintain its rainproof feature.

■ When installing it in low level, be careful with dead stock and material bridge.

■ If the measure object is fluid in the tank, set adequate time delay for the output relay.

■ Install a sun cover for outdoor installation so as to avoid the influence of temperature rise.

■ If there is an agitator, keep safety distance between the agitator and probe.

■ When installing the sensor, avoid places with a lot of vibration or obstacles.

■ The fluid flow is severe near the outlet, and it is easy to cause mechanical damage or

chattering, so installation near the outlet should be avoided.

■ It is necessary to check if the temperature and pressure generated inside the tank meet the

specifications.

■ If the temperature of the housing is significantly different from the ambient temperature, a

solvent filling or Gortex (Ventilation) shall be applied prior to use, as condensation may

occur.

■ Use the same standard flange or screw.

■ Make sure to insert gaskets between flanges.

The user shall determine if the product involved is an Ex-proof zone and

install the appropriate product.

Cautions

For

Removal

Wiring

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

■ The product may be overheated so wear gloves to prevent burns.

■ If there is explosive gas in the atmosphere, do not open the cover.

■ To open the cover of an ex-proof product, release the SET SCREW (ex-proof key) first.

■ Disconnect the power first.

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

the product cover.

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

In the case of explosion-proof products, apply power after fastening the cover

after wiring.

■ Connect AC (90–240 V) or DC (24 V) according to the power specifications.

■ Make sure to connect the power with the correct polarity (+, -).

■ Do not connect the wire with the power connected.

■ This product provides DPDT. Wire it with COM and NO terminal to use HIGH contact.

■ Make sure to connect it to an external ground.

If there is an atmosphere of explosive gas and explosive dust, do not open the product cover.

Precautions

for Use

Safety and

Environment

■ Users should use appropriate products by judging the explosion-proof area of the related

products.

■ Do not bend the sensor, which is the measurement part, or cut or expand it arbitrarily.

■ Apply power after installation is completed and cover of product is fastened.

■ Do not use when the ambient temperature range (-20~+60℃) is exceeded.

■ Do not use when the degree of protection is higher than the IP66 condition.

■ It should not be used where there is vibration.

■ 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

- Make sure to wire contacts correctly (refer to Wiring)

- Internal ground (inside product housing) and external ground shall be connected.

- 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.

Cautions

for

Inserted

External Wire

Failure Check

And

Maintenance

■ Use the cable gland connection or metal pipe line lead-in on the wire inlet, and use

a product with an equivalent ex-proof certificate to connect it using the external line

lead-in method.

■ For an unused external line inlet, use a closing plug with an equivalent ex-proof certificate.

■ Precautions for ground connection

- The location of the external ground is as follows, and when connecting to the ground

wire must be 4㎟ (4mmSQ) or more. (Internal grounding should be connected with

the same specifications as the connection cable.)

Washer must be used when reconnecting after disassembling the terminal lug to the

ground terminal. (Anti loosening)

External ground

■ Inspection

The sensor and transmission parts of a capacitive-level transmitter must be inspected.

Their service lives depend on the user environment and can be optimized with regular

inspection. As such, users are advised to conduct regular inspections and maintenance at

least every year. The exterior damage will be visually inspected, and any object to be

measured and foreign substance will be regularly removed from the probe as these can

affect accuracy.

When removing them, prevent causing damage to the Teflon.

■ Failure Check

1) Is the power connected correctly?

2) Is the power voltage correct?

3) Is the cabling correct?

4) Is the green LED turned on?

During maintenance, the power to the product must be completely cut off

before inspection.

Do not disassemble while power is applied in an explosion-proof area.

Read and understand the aforementioned and make sure that the temperature of the object

to be measured does not exceed 800℃ for general purpose. For an ex-proof type, the

maximum is 150℃. In addition, make sure that the ambient temperature of the housing is

kept at -20 – +60℃.

An ex-proof product is a pressure-resistance and ex-proof type, so do not open the cover

while using it.

Do not apply a non-ex-proof product in an ex-proof zone.

An ex-proof product can be used where the environment and containers of the

object to be measured are type 1 and 2.

Sensing Probe can be a source of ignition because it operates on the principle

of Capacitance. Therefore, the tank interior is a non-hazardous area and cannot be

used in locations containing flammable products.
