G-C characteristics ?
The property that the compensation capacity (response capacity C) automatically increases 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, and the detection sensitivity decreases to prevent malfunction.

Any power source
Most of the equipment operates at a fixed voltage of AC100V and AC200V according to the general voltage in Japan.
However, there are many different voltages in foreign countries, and there is also a direct current of 24V DC.
"Any power source" is indispensable when exporting equipment from Japan or using an unstable power source.
Switchable Relay contact and Photo coupler
It is up to you to decide the output setting of the relay contact or the photo coupler.
■To set the output to the relay contact, connect the "jumper pin (yellow pin)" to "A1" under the relay.
■To set the output to the photo coupler, connect the "jumper pin (yellow pin)" to "A2" under the relay.
※Be sure to set the output to either the relay contact or the photo coupler before connecting.
The output setting after wiring may cause the amplifier to malfunction.
Fail-safe function included
This product has a built-in fail-safe function.
■For normal (not fail-safe) settings, set the changeover switch to the right so that the knob fits within the white line.
■When setting to fail-safe, set the changeover switch to the left side so that it deviates from the white line.
※You can easily and quickly change the settings according to your usage.
Switchable standard and Z type
You can switch the amplifier setting according to the detection status by inserting and removing the red jumper pin.
When you pull out the red jumper pin that is inserted, "Z type" will switch to "standard".
■Put on red jumper pin →「Z type」Amplifier.
■No red jumper pin →「Standard」Amplifier.
※「Z type」Amplifier …
This amplifier was developed for the detection of substances whose object to be measured is semi-conductive and has a relatively low dielectric constant (eg cast sand).
Delay
You can make it delay for up to about 5 seconds by the situation at the site.
When liquid or powder is not stable and it is necessary to prevent chattering of the relay, the output can be easily stabilized by simply turning the variable knob.
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.
