DS-type(Explosion-proof type 3nG5)
We have a lot of amplifiers or electrodes for using in a variety of materials as flour, grain, liquid.
The basic design concept is "ease of maintenance".
We will respond to your request, even if it is limited applications OEM product or advanced technical requirements.
- ◆The electrode and amplifier case are integrated.
- ◆The amplifier unit is stored in the amplifier case.
- ◆The power supply has a safety retention element.
- ◆It consists of two parts, an electrode and a power supply (barrier).
- ◆Connect the electrode and power supply with a 2-core shielded cable.
Various electrode shapes
We offer electrodes of various shapes.

We can customize our products for use in powders, granules and liquids, prepare amplifiers and electrodes according to the application.
Amplifier
| Amplifier model | Maximum sensitivity | Characteristic | Explosion-proof |
|---|---|---|---|
| Standard | 0.5pF | General type | ○（Separate type） |
| C-type | 0.5pF | Low sensitivity（Wide range）type | ○（Separate type） |
| Z-type | 0.5pF | Technical（G-C）characteristic improvement type | ○（Separate type） |
Technical（G-C）characteristic
The characteristic that the compensation capacity（response capacity C） automatically increases and the detection sensitivity decreases to prevent malfunction in response to the decrease in resistance value（increase in conductivity-G・decrease in insulation）due to the adhesion of conductive substances to the electrodes.
Electrode and amplifier section separated type
Separated type be used when the electrode mounting area vibrates.
Small case type
This electrode can be installed in dust or water.
Connect the amplifier and electrodes with a dedicated coaxial cable.
（Up to 5m）
L-shaped connector type
If the installation location is narrow, use a connector type.
※The connector is not dust-proof and drip-proof.
Connect the amplifier and electrodes with a dedicated coaxial cable.
（Up to 5m）
S-shaped connector type
If the installation location is narrow, use a connector type.
※The connector is not dust-proof and drip-proof.
Connect the amplifier and electrodes with a dedicated coaxial cable.

Operating principle
★Empty★
When tank is empty,there is just air between the electrode and the tank wall.
so, Capacitance is very small.
★Object in a tank★
When the material enters between electrode and the tank walls, the capacitance increases in proportion to the dielectric constant which the material has. This product captures the incremental capacitance to output as the contact signal.
