[Demo units available] Capacitive sensor "Capacitive proximity sensor"

[Demo units available] Capacitive sensor "Capacitive proximity sensor"

Detect the liquid level from outside the container without touching the liquid! It can detect a wide range of liquids and powders without being affected by the transparency of the object or the reflection of light!

The "Capacitance Proximity Sensor" is a proximity sensor equipped with semiconductor switching elements that generates an electric field within the detection area. It uses a part of the circuit as a conductive electrode, and by having another conductor or dielectric approach this electrode, it detects the proximity of an object by converting the change in the electrode's capacitance into an electrical signal. 【Features】 ■ Detects liquid level simply by mounting it on the side of a container! ■ Capable of detecting transparent objects such as water and glass! ■ Wide detection range from fine powders like rice bran to coarse powders like coffee beans! *Demo units are available for loan! For more details, please download the PDF or feel free to contact us.
