Capacitance Sensor
Product tags：
Overview
This sensor detects changes of capacitance/impedance. Application examles are liquid level and concentration sensors, etc.
Since the detection electrode is protected by ultra-thin ceramic layer, it can be used for various liquids.
We can customize the material, thickness of protective film and electrode pattern as per customers' requirement.
Example of Structure
Electrode pattern
A-A’ Cross-sectional structure
Measurement principle
Detecting change of capacitance/impedance by change of surface condition on the sensor.
Application examle
- Liquid level sensors for corrosive and reactive liquid
- Concentration sensors for chemical liquid
- Condensation sensor
- Gas sensor
- Particle sensor
- Space potential sensor
