Abstract
The utility model provides a kind of sensor structure of radio frequency admittance analyzer of water content, from inside to outside successively include central electrode, shielding center electrode layer, shielding electrode layer, shield dielectric layer and ground electrode layer, into hierarchic structure, described ground shield dielectric layer, which extends to, all coats the central electrode, shielding center electrode layer, shielding electrode layer for the central electrode, shielding center electrode layer, shielding electrode layer, the end face of ground electrode layer.Compared with the prior art, the utility model has the advantage that：Direct dead short between central electrode and ground electrode layer is avoided when medium is conductive material, the oily analyzer of water content of the radio frequency admittance measuring principle made generates effectively measurement to highly aqueous aqueous mixtures change in dielectric constant caused by aqueous.
Description
Technical field
The utility model belongs to radio frequency admittance analyzer of water content technical field, more particularly, to a kind of radio frequency admittance moisture content
The sensor structure of analyzer.
Background technology
Radio frequency admittance analyzer of water content often uses the sensor structure of below figure 1, which is suitable for low contain
The aqueous measurement of water section oil, for the oil product of low water-bearing section, medium is equivalent to nonconducting medium or normal for low dielectric
Several media, being measured for the sensor of this principle has no problem, but for the oil product of High water cut, in measurement
Due to there is no insulation measures that can cause two electrode direct short-circuits between central electrode 5 and ground electrode 1, and then application can not be measured.
The content of the invention
In view of this, the utility model is directed to a kind of sensor structure of radio frequency admittance analyzer of water content, to avoid
The possibility of short circuit occurs between central electrode and ground electrode layer.
In order to achieve the above objectives, the technical solution of the utility model is realized in：
A kind of sensor structure of radio frequency admittance analyzer of water content includes central electrode, shielding center successively from inside to outside
Electrode layer, shielding electrode layer, shield dielectric layer and ground electrode layer, the central electrode, shielding center electrode layer, bucking electrode
Into hierarchic structure, described ground shield dielectric layer is extended to the central electrode, shielding central electrode for layer, the end face of ground electrode layer
Layer, shielding electrode layer all coat.
Compared with the prior art, the utility model has the advantage that：
(1) direct dead short between central electrode and ground electrode layer is avoided when medium is conductive material, what is made penetrates
The oily analyzer of water content of frequency admittance measurement principle has highly aqueous aqueous mixtures change in dielectric constant caused by aqueous
Effect measurement；
(2) it is simple in structure, it is easy to implement.
Description of the drawings
The attached drawing for forming the part of the utility model is used to provide a further understanding of the present invention, this practicality is new
The schematic description and description of type does not form the improper restriction to the utility model for explaining the utility model.
In attached drawing：
Fig. 1 is the sensor structure of traditional radio frequency admittance analyzer of water content；
Fig. 2 is the sensor structure of the radio frequency admittance analyzer of water content described in the utility model embodiment.
Reference sign：

Specific embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
A kind of sensor structure of radio frequency admittance analyzer of water content, as shown in Fig. 2, including central electrode successively from inside to outside
5th, shield center electrode layer 4, shielding electrode layer 3, shield dielectric layer 2 and ground electrode layer 1, the central electrode 5, shielding center
Electrode layer 4, shielding electrode layer 3, the end face of ground electrode layer 1 into hierarchic structure, described ground shield dielectric layer 2 extend to will be described in
Heart electrode 5, shielding center electrode layer 4, shielding electrode layer 3 all coat.
It is coated entirely by the way that ground shield dielectric layer 2 is extended to center-side, so as to add in central electrode 5 and ground electrode layer 1
Enter one layer of separation layer, direct dead short between central electrode 5 and ground electrode layer 1 avoided when medium is conductive material,
The oily analyzer of water content of the radio frequency admittance measuring principle made is to highly aqueous aqueous mixtures change in dielectric constant caused by aqueous
Generate effectively measurement.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modifications, equivalent replacements and improvements are made should be included in the utility model
Protection domain within.
