The capacitance of detection judges the corrosive grade of environment.The bar number of the film for being consumed and the capacitance for being detected judge environment
Corrosive grade relation is as shown in table 1:
Table 1:The bar number of the film of consumption and the capacitance for being detected judge the corrosive grade relation of environment
Generally, sensor is in consumption process, and the time that thin metal film 3 is exhausted is shorter, thick metal
The time that film 3 is exhausted is longer.Also, in same atmospheric environment, the film consumption of the same specification of four kinds of metal materials
Finish time phase difference less, but be not precluded within certain atmospheric environment, the wear rate of one of which metal film 3 is fast compared with other.
Corrosiveness of the environment classification testing result reference table is set up for this.
In table 1, when all films are not all consumed, the detection value of electric capacity 4 should be 12400pF, corresponding atmospheric environment
Corrosion class is 1 grade.Certainly it is that a certain minimum gauge metal film 3 runs out of when consuming any 1 in material in four
Finish, now capacitance is 12300pF, and the corrosive grade of environment can not be judged accordingly for 2 grades, should be still 1 grade, use formula:3C1+4
(C2+C3+C4+C5) represent, therein 1,2,3,4,5 represent respectively first group of detector unit, 2, second group of detector unit 2 ...,
It is identical with first digit meaning in detection means, all it is to represent some detector unit 2.Wherein 3C1 represents first group of detection
Have in unit 2 metal film 3 be consumed cause fracture, 4 (C2+C3+C4+C5) represent second and third, four, five groups of detector units 2
In 4 metal films 3 be not consumed cause fracture, when consuming 2, it may be possible to which the metal film 3 of two minimum gauges disappears
Consumption, now detects that the value of electric capacity 4 is 12200pF, still not can determine that corrosiveness of the environment grade for 2 grades, should be still 1 grade, uses formula:
2C1+4 (C2+C3+C4+C5) represents have two metal films 3 to be consumed fracture in that is, first group detector unit 2, and other four groups
Metal film 3 in detector unit 2 does not rupture, and when consuming, the minimum that two metal films 3 are certain metal material is little by two with secondary
Gauge metal film 3 is planted, this reflects that the metal material is more sensitive in this kind of atmospheric environment, the detection value of electric capacity 4 is
12100pF, now the atmospheric environment is stronger to the corrosivity of the material, and the corrosive grade that environment can be evaluated is 2 grades.Use formula:3
(C1+C2)+4 (C3+C4+C5) represent, by that analogy, according to detection electric capacity 4 value can Fast Evaluation atmospheric environment corrosivity etc.
Level, table 2 below is corrosiveness of the environment classification testing result reference table.
Table 2 is corrosiveness of the environment classification testing result reference table
Embodiment 2:
As shown in figure 3, as another embodiment, the detection means of same metal material can be put together,
Four detector units 2 are material is thus formed, has five detection means, five in every group of detector unit 2 in each detector unit 2
Detection means is same metal material, and the metal material for so assuming first group of detector unit 2 is iron, and five detection means are divided
Bian Hao not be C11, C12, C13, C14 and C15, the metal material of second group of detector unit 2 is copper, and five detection means are compiled respectively
Number it is C21, C22, C23, C24 and C25, the metal material of the 3rd group of detector unit 2 is zinc, and five detection means are numbered respectively and are
C31, C32, C33, C34 and C35, the metal material of the 4th group of detector unit 2 is aluminium, five detection means number respectively be C41,
C42, C43, C44 and C45, its result of calculation is identical with the result of calculation in embodiment.
