Electrochemical sensors are devices that convert a chemical signal into an electrical one. They are used in a wide range of applications, including moisture testing.
The most common type of electrochemical sensor used for moisture testing is a capacitance sensor. Capacitance sensors measure the change in capacitance between two electrodes as the moisture content of the material changes. Other types of electrochemical sensors that can be used for moisture testing include:
Electrochemical sensors work by detecting the change in electrical properties of a material as its moisture content changes. When the moisture content of a material increases, the electrical conductivity of the material also increases. This change in conductivity can be detected by an electrochemical sensor, which then converts the signal into an electrical one.
Electrochemical sensors offer several advantages for moisture testing, including:
