Abstract
A real-time monitoring device for an amount of surface salt deposition comprises a host and a monitoring probe. The host generates a fixed frequency AC excitation signal and transmits it to the interdigital electrode inside the monitoring probe. And then the host analyzes a feedback signal to obtain an information of impedance value. The amount of salt deposition on the interdigital electrode surface is determined by a predetermined relationship curve between the amount of salt deposition and the impedance value, and the actual amount of salt deposition in the environment can be obtained. The monitoring device can change the relative humidity of the environment around the interdigital electrode by adjusting the temperature, so that the salt deposited on the surface of the interdigital electrode absorbs moisture and forms a liquid film, achieving real-time monitoring of the amount of salt deposition on the surface of the interdigital electrode.
