Detection sensor

Ceramic technology

Capacitance sensor

NGK realizes the capacitance sensor with high chemical/corrosion resistance and high sensitivity by protecting detecting electrodes with the ultra-thin protective ceramics layer. Our capacitance sensor can detect the liquid volume and concentration of corrosive and chemical liquid and detect the conductivity of high purity solution and detect gas, particle, and space potential. NGK can customize as per the customer’s request. Please feel free to contact us.


High reliability

Ceramics with high chemical and corrosion resistance protect detecting electrodes.

High sensitivity

Ultra-thin protective ceramic layer realizes high sensitive detection of liquid.


Application examples of our capacitance sensor are as following which requires high chemical/corrosion resistance and low contamination.
