The utility model has the advantages of simple structure, good shock resistance, easy assemblage and transport, thereby overcoming the influence, which is coursed by the inhomogeneous physical property of the materials, on measurement accuracy.
Description
The utility model relates to a kind of measurement mechanism, specifically a kind of flexible quasi-sectional capacitance material level sensor.
We know, for solid material in the specific feed bin (powdery or bulk) amount what, utilizing the capacitive transducer measurement is one of more convenient at present, practical means.ZL91108963.2 and ZL94100133.4 disclose two kinds of sectional type level sensors, wherein the implementation method that provides of ZL91108963.2 patent is as central supported with wire rope, sheath, heart yearn, passive screen layer, insulation course, segmented electrode layer etc. have been set gradually in the wire rope outside, the advantage of this invention is to have realized flexible structure on the whole, be easy to install, transport, but because the structure of Sensor section is too complicated, be difficult to guarantee between each several part problem not to take place, also be unable to undergo washing away for a long time of various materials, thereby can not be advantageously applied to actual measurement.The ZL94100133.4 patent has provided a kind of sectional capacitance structure of column, and its advantage is to have simplified the electric capacity segmented structure, but because it is the supporting mass of sensor with the insulating material, problems such as its intensity, reliability are difficult to solve, and lack practicality.
The purpose of this utility model is exactly to provide a kind of level sensor in order to overcome above-mentioned the deficiencies in the prior art, and its impact resilience is strong, be easy to install, transportation, and can overcome because the inhomogeneous influence to measuring accuracy of physical property of material.
For achieving the above object, the utility model can be realized by following measure: it is provided with the metal main pole, metal main pole top is provided with the fixing ring flange of using, ring flange top is provided with capacitive pick-up, the metal main pole is fixing with ring flange and feed bin insulation by insulating mat, main pole and feed bin bulkhead are respectively a utmost point, constitute and become the medium continuous capacitance, its technical characterstic is that the metal main pole is composed in series by more piece tubulose split pole, be provided with insulation course between two adjacent split pole ends, tubulose divides very two-layer compound sleeve type structure, and pipe and outer tube are provided with insulating material between outer tube and the interior pipe in being provided with.
The utility model also can be realized by following measure: interior pipe two ends is respectively equipped with mortar head, mortar bowl, adopt mortar head, mortar bowl formula to cooperate between the two adjacent joint inner tube portions, be respectively equipped with cable aperture and cable wire hole on mortar head, the mortar bowl, cable wire passes the cable wire hole and in interior pipe pipe in each joint is fixed together.The outer tube madial wall links to each other with capacitive pick-up through cable, insulate by insulation course between the adjacent outer tube.
The utility model flexible quasi-sectional capacitance material level sensor simple structure, impact resilience is strong, be easy to install, transportation, and can overcome because the inhomogeneous influence to measuring accuracy of material physical property.
The utility model will be further described by embodiment below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
