Product Details

Overview

HT(HPC)-100CT 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.

 

 

 

Characteristics

- Widely used to measure various liquid levels

- Strong structure and semi-permanent life cycle due to moveless part

- Various probe types for wide application

- Easy installation of wire type (HT-100CTW/HT-100CTW-2)

- Applicable to corrosive liquid

- Interface measurement between water and oil is available.

- Applicable to explosion area (HPC-100CT/HPC-100CT-2)

- NAMUR NE43 is applied.

 

 

Operation Principle

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 constant ε1 exists in the space between two concentric conductors, lower part of space between two conductors is filled with material of dielectric constant ε2 as shown below, the change of capacitance is expressed as follows.



Since is a constant value as an initial condition, and get this value as K, △C becomes a function of level of material only. Therefore, level can be obtained through the measurement of △C.

 

 

ε1 : Dielectric constant of air

ε2 : Dielectric constant of medium

L : Height of tank

I : Level of medium

D : Outer diameter of tank

d : Outer diameter of sensing probe

Installation

Below recommendation should be considered when installation.

(a) Product should be installed at the place far from inlet in order to avoid malfunction.

(b) Protection tube should be applied if there is a flow or slopping of the medium in the tank.

(c) Probe should be installed within Max. 300mm from the tank wall and ground tube type should be applied if the distance between the tank wall and sensing probe is far or the tank material is non-conductive.

(d) Ground rod type should be used for corrosive liquid.

(e) Bracket insulated to a sensing probe should 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.

Ground tube or ground rod type should be applied for concrete or non-conductive tank as per above figure.

Ground tube type should be applied for ball tank and external chamber should be installed for side mounting of tank.
