Abstract
The utility model provides a static capacitance sensor which includes an outer shell whose inner is provide with a circuit board and is connected with an indicating light and a sensitivity regulator. An arc shaped embedding groove is also arranged for simply embedding an arc shape electrode plate and is sealed by an end cover; an arc shape induction face is arranged at the other side of the outer shell which can effectively approach the surface of the object being measured; the increased induction area can increase the sensitivity of the sensor for measuring the static capacitance.
Description
Technical field
The utility model relates to a kind of static capacity sensor.
Background technology
Having the static capacity sensor now mainly is to utilize the battery lead plate of a plane formula directly to be welded on the circuit board, coats with circular or square shell again, relies on the next static capacity near determinand of inner battery lead plate, to measure its electric storage numerical value.But because of battery lead plate is plane, and the surface of contact of shell and general cylindrical appearance is a straight line only, goes up relatively, and the distance of battery lead plate and determinand is just farther, so the area that can respond to is less, and can't effectively measure actual static capacity numerical value.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is: provide a kind of static capacity sensor, to improve its measuring accuracy.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of static capacity sensor includes a shell and a tail-hood, and its inside is provided with a circuit board, it is characterized in that: the side combination of described circuit board has the arc-shaped electrode plate, and the same side of shell is made as the circular arc sensitive surface.
Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be: can press close to the outside surface of columniform determinand, increase whole induction area, improve induction precision.
Description of drawings
Fig. 1 is an exploded perspective view of the present utility model;
Fig. 2 is a combination stereogram of the present utility model;
Fig. 3 is an embodiment reference diagram of the present utility model.
Description of reference numerals: 1-shell; 11-circular arc sensitive surface; The 2-circuit board; The 21-pilot lamp; 22-circular arc embeded slot; 3-arc-shaped electrode plate; 4-sensitivity regulator; 41-adjusts button; The 5-tail-hood; The 6-determinand.
Embodiment
See also Fig. 1, shown in Figure 2, the utility model includes a shell 1, be provided with a circuit board 2 in it, can be in conjunction with a sensitivity regulator 4 and a pilot lamp 21 on the circuit board 2, the one side then is provided with a circular arc embeded slot 22, can be fixed easily for arc-shaped electrode plate 3, its outside is to utilize a tail-hood 5 sealings, described tail-hood 5 establishes that adjustment button 41 that several perforates make induction regulator 4 can expose and the light of pilot lamp 21 is penetrated, in addition again in conjunction with showing the panel 51 of measuring numerical value with one.Shell 1 also is provided with circular arc sensitive surface 11 similarly near a side of battery lead plate 3.
During use, can control earlier and adjust button 41 to set its sensitivity, then cylindrical determinand 6 is affixed to circular arc sensitive surface 11, as Fig. 3, this is the battery lead plate 3 that is close to relatively in it, the battery lead plate 3 and the whole sensitive surface of determinand 6 are significantly promoted, therefore be can be correctly and the actual storage of effectively measuring its static capacity, and failed comparable by existing mode.
Be to know, enforcement of the present utility model effectively increasing under the prerequisite of induction area, obviously can improve the effect of induction, and to the actual storage of static capacity of determinand, obtains more correct numerical value.In addition, the utility model utilizes chimeric battery lead plate of easy means and circuit board, also has progressive effect.
More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
