Capacitive level sensors take advantage of the difference in dielectric constant between air and most liquids to non-invasively measure the presence or absence of liquids in a container non-invasively. They’re ideal for detecting liquids inside of thin-wall non-conductive vessels.
Every application is different, and suitability depends on a range of factors, but the table below is intended as a starting point to decide whether capacitive sensing is right for an application.
Capacitive level sensors work with a wide range of materials and applications, and they also have the advantage of being mechanically simple with no moving parts and minimal required maintenance. They are well-suited for both point and continuous level measurements in disposable and non-disposable applications. These sensors may also be referred to as Capacitance Level Sensors
