Fig. 2 is the elongation state structure diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, the utility model provides a kind of adjustable capacitance level gauge of range, including electronics storehouse 1
And electrode, electrode lower part are lower end caps 8, electrode includes upper segment electrode and lower segment electrode, and upper segment electrode includes 5 He of electrode in epimere
Epimere external electrode 2, lower segment electrode include electrode 6 and hypomere external electrode 3 in hypomere, and electrode 6 is sleeved on electrode 5 in epimere in hypomere
Inside, hypomere external electrode 3 is sleeved on the inside of epimere external electrode 2, and the external of electrode 6 is set in electrode 5 and hypomere in epimere
There is an insulation sleeve 4, electrode 5, epimere external electrode 2 and 4 top of insulation sleeve are fixed on 1 lower part of electronics storehouse in epimere, electrode 6 in hypomere,
Hypomere external electrode 3 and 4 lower part of insulation sleeve are fixed on lower end cap 8, and epimere external electrode 2 is opposite with 3 junction of hypomere external electrode
Both sides are connected by fastener.
Fastener can be screw or rivet, and the present embodiment is using screw 7 as fastener, the both sides of epimere external electrode 2
A fixed hole position is each provided with for fixing screws 7, the both sides of hypomere external electrode 3 respectively symmetrically are provided with multiple mounting holes
Position 9 is used to fix the screw 7 on epimere external electrode.
Insulation sleeve 4 uses flexible electrical isolation material, and this material includes but not limited to fluorubber, nitrile rubber
Metal tube is used Deng, external electrode, lower end cap is conductor or non-conductor, can be aluminium alloy or stainless steel or plastics etc..
Electrode 5 and epimere external electrode 2 are single hop capacitance structure or multistage capacitance structure in epimere.
Electrode 5 and epimere external electrode 2 and the size of electrode 6 and hypomere external electrode 3 in hypomere are into certain ratio in epimere
Relationship, it is balanced, linear that this ratio, which ensures that the capacitance that upper-lower section internal and external electrode is formed is compared,.
