Problems solved by technology
[0002] The outer tube size of the coaxial guided wave radar in the prior art is at least 20mm, that is, if the opening size of the container to be measured on site is less than 20mm, the coaxial guided wave radar cannot be used for measurement
[0003] For example, some small high-pressure tanks basically have small openings, which limits the use of coaxial guided wave radar
[0004] The interior of the coaxial guided wave radar in the prior art often uses low dielectric constant plastic or ceramics as supports. The structure of the supports in the prior art leads to discontinuity in the wave impedance, thereby forming reflected waves, making low The dielectric constant of liquids cannot be measured

The invention provides a probe assembly of a coaxial guided-wave radar, and the probe assembly comprises a central conductor which is used for guiding an electromagnetic wave generated by the coaxial guided-wave radar for emission, and guiding a returned electromagnetic wave; an outer wall pipe which is arranged outside the central conductor in a sleeving manner, wherein the central conductor and the outer wall pipe have the same extending direction; and an insulating support part which is made of an insulating material, the insulating support part is arranged between the central conductor and the outer wall pipe so as to insulate the central conductor from the outer wall pipe, the insulating support part enables a continuous channel to be formed between the central conductor and the outer wall pipe along the extending direction of the central conductor, and liquid can pass through the continuous channel. The invention also provides the coaxial guided-wave radar.
Description
technical field [0001] The disclosure belongs to the technical field of guided wave radar, and particularly relates to a probe assembly of a coaxial guided wave radar and a coaxial guided wave radar. Background technique [0002] The outer tube size of the coaxial guided wave radar in the prior art is at least 20mm, that is, if the opening of the container to be measured is smaller than 20mm, the coaxial guided wave radar cannot be used for measurement. [0003] For example, some small high-pressure tanks basically have small openings, which limits the use of coaxial guided wave radar. [0004] The interior of the coaxial guided wave radar in the prior art often uses low-dielectric constant plastics or ceramics as supports. The structure of the supports in the prior art leads to the discontinuity of the wave impedance, thereby forming reflected waves, making low The dielectric constant of liquids cannot be measured. [0005] It is required that the intensity of the reflect...
