Capacitance level meters

CGL series

Compatible with battery sized ultra-small tanks High-sensitivity level meter that captures changes in minute capacities

It is a capacitance type level meter that can measure with high accuracy even in a battery / test tube size ultra-small container. The amplifier section is also "business card size" and is ideal for installing small devices in narrow spaces. There are few dead zones, and measurement is possible with the entire sensor.
*Sensor electrodes can be customized.
*Can be used with simple initial settings, using pushbuttons.

We have a lineup of CGL type dedicated to level measurement and WGL type compatible with moisture meters and analyzers.

Features, keys

Achieves ultra-high sensitivity and high accuracy even in a small size
High accuracy (± 1% accuracy) is achieved even in short size (height 50-60 mm) level measurement.
The separation amplifier is also the size of a business card and can be easily incorporated into a small device.
Displaying measured values in real time with a display
The display is mounted on a separating amplifier.
The current measured value (% display) and capacitance value (pF display) are displayed in real time.
Simple initial setting
It is easy to make the zero and span setting, using pushbuttons.
BNC connecter make it easy to connect and disconnect the sensor and cable
Reduces connection mistakes between the sensor electrode cable and the separating amplifier.

Applications

Various oils are used in industrial equipment such as machine tools, but it is possible to measure the remaining amount of small tanks and oil pans in narrow spaces with high accuracy. Even a test tube size tank or a tank with a range of several centimeters can be measured in millimeters.

Usages, use examples

Measure liquid level, powder and granular material level in various tanks. Measure material interface of liquids.
Conductive or insulating liquids, insulating liquids with a small dielectric constant, and semi-conductive liquids.
Ex.: Various oil, various chemical solutions (acids, alkalis), various washing liquids, tap water, pure water, distilled water, alcohol, etc.
Small unit tanks, small container.
