Abstract
The utility model relates to a non-uniform corrosion detecting probe, which is provided with an insulating casing of which the inside is provided with a metallic piece and a detecting electrode. The utility model is characterized in that the inside of the casing is provided with a signal amplification circuit board, and an insulating water-absorbing layer is arranged between the metallic piece and the detecting electrode. The utility model, which has the advantages of simple structure, easy fabrication and low cost, has very high sensitivity for detecting metallic non-uniform corrosion.
Description
The utility model relates to a kind of device that detects metal erosion, particularly relates to a kind of unsymmetrical corrosion detection probe.
Metal erosion comprises that oceanographic engineering generally is divided into two kinds of uniform corrosion and unsymmetrical corrosions with the corrosion of steel.The unsymmetrical corrosion phenomenon can occur on the particularly apertured position, junction surface of metal parts, or when being subjected to situations such as local acidifying and occur.Unsymmetrical corrosion often adopts potential method to detect, and used detection probe generally comprises sheet metal, electrode and lead-in wire etc.Though it is conventional device can both be measured the corrosion of metal situation effectively, generally sensitive inadequately.
The purpose of this utility model provides a kind of unsymmetrical corrosion detection probe of sensitivity, and it can remedy the above-mentioned deficiency of existing detection probe.
A kind of unsymmetrical corrosion detection probe has an insulation crust, and sheet metal and detecting electrode are housed in this shell, it is characterized in that being equipped with in the shell signal amplification circuit plate, and the insulation water accepting layer is housed between sheet metal and detecting electrode.
The utility model is simple in structure, makes easily, and cost is low, and the sensitivity that is used to detect the metal unsymmetrical corrosion is high.
Below by embodiment and description of drawings the utility model.
Accompanying drawing is a structural representation of the present utility model.
The utility model has an insulation crust 3, and sheet metal 5 and detecting electrode 4 are equipped with in the top in this shell 3, it is characterized in that being equipped with between sheet metal 5 and the detecting electrode 4 water accepting layer (not drawing among the figure) of a utmost point book.Signal amplification circuit plate 2 also is housed in the shell.Sheet metal 5 and detecting electrode 4 are connected to lead 1 and 6 respectively.When using the utility model, lead 1 and 6 is connected on pot or the conductivity meter, by known method mensuration sheet metal 5 and current potential or the resistance between the detecting electrode 4.When the sheet metal of being made by detected steel 5 unsymmetrical corrosions take place the pitting penetration phenomenon occurs, just there is electrolyte solution to see through water accepting layer,, will soon on surveying instrument, shows so resistance between two leads and current potential just are worth near 0.
