Capacitance is the ability of a system to store an electric charge. In a capacitive sensor, two electrodes are separated by a dielectric (air, liquid, or solid material), forming a capacitor. When an object enters the electric field generated by the sensor, it alters the capacitance. This change is detected and interpreted by the sensor …
Rechner Sensors’ ability to design and manufacture capacitive sensors tailored to precise requirements, even in small quantities, offers significant advantages to customers. Customers can get sensors designed specifically for their unique applications, ensuring optimal performance and fit. Being able to cater to small quantities means Rechner Sensors can accommodate niche or specialized needs without requiring …

A capacitive level sensor is a proximity sensor that is used to detect liquid levels, interface between liquids such as oil and water, or liquid and solid interface. They operate on the principle of capacitance whereby in the simplest form of a level sensor, a capacitor is formed with the vessel containing the material to …
Capacitive sensors work by measuring the dielectric of the material around the sensor. This dielectric value increases both when there is more material in front of the sensor and the closer that the material gets to the sensor. This means that capacitive sensors work differently than inductive proximity sensors. Capacitive sensors can detect virtually any …
