Level indicator（Glass gauge type）GR-120
Discontinuation of production
Thank you for using this product long time.
We discontinued this product because the supplier has stopped the production of parts.
We have finished accepting orders as of january 18, 2023.
※Repairs cannot be accepted because parts are not available. Please understand.
This is a product that can monitor the liquid level visually by glass gauge and can also be monitored by electrical control.
We attached two long thin metal sheets facing each other to the surface of the glass tube. One is the sensing electrode and the other is the ground electrode.
Electricity is stored between two electrodes. This is capacitance.
The capacitance value increases or decreases according to changes in the liquid level in the glass tube. This product converts changes in capacitance value into electrical signals.
In addition to glass tubes, it can also be used for Teflon and resin tubes. It is ideal when metal ions are not available.
Feature
●You can check the liquid level through the gap between the two electrodes even if the sensors are attached.
●You don't have to put the float inside the glass tube.
●You can use this product even for chemical liquids because the sensor and the liquid do not contact each other.
●You can install the sensor simply by replacing the existing glass tube with the electrode-equipped glass tube that we provide.
※Please send us the glass part of the gauge if it is not a general type.
We will deliver the product with electrodes attached.
