Overview

HCC(HPC)-95P Series is a Capacitance Type Level Switch and it detects a level of medium by sensing of capacitance value change caused by dielectric constant of each medium.

Characteristics

- Widely used for various type of medium such as solid, powder and liquid

- Applicable to the medium which has low dielectric constant

- High sensitivity and stability

- Semi-permanent life cycle due to moveless parts

- Easy installation and calibration

- Operating can be checked at the site.

- Available to the tank which has an agitator

- Various sensor types can be applied according to installation condition at the site.

Operation Principle

When an air surrounding the electrode probe is replaced by other medium, the capacitance value is changed according to the dielectric constant of the medium. Once the electrode probe is touched by the medium, the capacitance value is increased and the level switch activates relay output by converting of the changed capacitance value to the electronic signal.

Applications

- Liquid

Various fuels, Solvent, Acids, Alkali, Liquefied gas and Pure water, etc

- Mixes Liquid

Industrial sewage, Urban sewage, Agricultural chemicals, Various sludge and aqueous solutions, etc

- Interface

Oil and water, Mercury in the water, Alcohol and acid, Sediment in liquid, Liquid and foam. etc.

- Material

Clay. Sludge, Varnish, Paint. Grease, Adhesive, Paraffin, Cheese and Honey, etc.

- Powder

Plastic powder, Rock powder, Carbon, Iron chloride powder, Silt, Sugar and Flour, etc.

- Granule

Plastic pellet, Metallic pellet, Chemical fertilizer, Medicine, Grain and Food, etc.

- Lump

Coal, Lime stone. Ore and Aggregate, etc.

HCC-95P(HPC-95P) Series is generally used for high or low alarm with the installation on the side or top of the tank and can be also applied to metallic or synthetic resin tank because the ground electrode is installed in the level switch and measurement is not affected by tank material.

 

 

 

1. Top Mounting Installation

 

This installation is not much affected by build-up of the medium on the probe but the sensitivity is lower than side mounting because it measures the level by the end of probe only, and it is not suitable to detect a level of the medium which has a low dielectric constant.

 

 

2. Side Mounting Installation

 

Highly sensitive measurement is available because it measures the level by whole of probe but it should be installed slopingly, forwarding of sensor to the bottom in order to avoid a malfunction caused by build-up of the medium on the sensing probe.

 

 

• If the probe length is below than 300mm 

- Min. 250mm distance between sensors

 

• If the probe length is below than 500mm

- Min. 350-400mm distance between sensors
