Abstract

The invention discloses a surface wettability sensor. The sensor comprises a signal source (1), a surface wettability sensing unit (2) and a detection output unit (3), wherein the signal source (1) generates an electric signal and provides the electric signal for the surface wettability sensing unit (2); the surface wettability sensing unit (2) detects surface wettability information and converts the information to a corresponding electric current signal; the detection output unit (3) converts the electric current signal of the surface wettability sensing unit (2) to a voltage signal to output; and the surface wettability sensing unit (2) comprises an insulator (6) and two metal wires (4, 5) which is wound on the insulator (6) in parallel, and the two metal wires separately form one detection electrode. The beneficial effects of the invention are as follows: sensor parameters are stable, the repeatability of the measuring result is good; the sensor is smaller and is more suitable to be used in narrow space; and electrode polarization and material consumption in liquid film can be avoided, thus the measuring result is more real.

Description

technical field [0001] The invention relates to a sample surface wetness measurement device for atmospheric corrosion test or environmental test, which is used for the measurement of the sample surface wetting time and the control of the wetness degree. Background technique [0002] The degree of surface wetting is a key factor in determining the rate of metal corrosion. This led to the development of the Atmospheric Corrosion Monitor (ACM) to measure the wetting time of sample surfaces in atmospheric environments. Since Tomashov introduced the atmospheric corrosion monitor into atmospheric corrosion research in the 1950s, it has become a relatively successful tool for researching and monitoring atmospheric corrosion through continuous research by Sereda, Kucera, Mattson, and Mansfeld. my country has used ACM for long-term monitoring of atmospheric corrosion since the 1970s. The existing ACM is divided into two types: one is the ACM of the double-electrode primary battery,...
