Embodiment approach

[0018] As an embodiment of the present invention, the conductivity cell 3 includes wires and electrodes for measuring conductivity, the water-absorbing test paper 1 covers the electrodes of the conductivity cell, and the electrodes are connected to external conductivity measuring devices through wires. Each electrode can be connected to a gold finger of the external conductivity measuring device through a wire, and electrical connections between wires, electrodes, and gold fingers that do not have a connection relationship should be avoided to cause a short circuit. If the substrate of the conductivity cell 3 is made of flexible material and becomes a flexible circuit board (FPC), the sensor of the present invention can be used to measure the salt content on a curved surface. Preferably, the substrate of the conductivity cell 3 can be made of a double-sided flexible copper clad laminate.

[0019] As a preferred embodiment of the present invention, such as figure 1 and figur...

Abstract

The invention discloses a sensor for measuring a salt content on the surface of a solid. The sensor comprises water-absorbing test paper, an anisotropic conductive film, a conductance cell and an insulating hydrophobic isolating device, wherein the water-absorbing test paper is bonded on an electrode of the conductance cell through the anisotropic conductive film; the anisotropic conductive film is electrically conducted in a direction perpendicular to the water-absorbing test paper and is insulated in a direction parallel to the water-absorbing test paper; the electrode of the conductance cell is electrically connected with an external conductivity measuring device; the insulating hydrophobic isolating device is used for preventing liquid in the water-absorbing test paper from diffusing to the external conductivity measuring device. By using the sensor, the defects that a to-be-detected sample needs to be sampled and detected (for example, a mural can be detected only after being subjected to micro core sampling) in the prior art are overcome; the additional sampling is not needed; the direct detection on the salt content on the fixed surface of the to-be-detected sample is realized; the destroy cannot be caused to the to-be-detected sample.

Description

technical field [0001] The invention relates to a sensor for measuring the salt content of a solid surface. Background technique [0002] Soluble salts cause various manifestations of diseases on the surface of murals and cause damage to murals. Determining the salt content on the surface of murals is of great significance for the prevention of salt damage of murals, the evaluation of desalination effect, and the prevention of secondary salt damage. The value of the mural itself requires that the method of detecting the salinity on the surface of the mural is non-destructive to the mural. [0003] However, the existing techniques for detecting salinity on the surface of murals all require micro-core sampling of murals before detection. After the sample obtained by sampling is soaked and filtered, the ion concentration in the sample solution can be measured by using the titration analysis method, so as to determine the salt content in the mural sample. This method requires...
