Abstract
The utility model provides a horn antenna with a dust shield, which belongs to the technical field of impulse radar material level meters, and comprises a vibrator, a horn-shaped antenna, a dust shield and a bar clasp, wherein the dust shield is fixed on the horn-shaped antenna by the bar clasp. The horn antenna obstructs dust, volatilized condensate and the vibrator from directly contacting through the mode of adding the dust shield, and therefore, the horn antenna avoids the problem of signal transmission attenuation caused by adhesive material formed around the vibrator.
Description
Technical field
The utility model is the design about the pulse radar level meter, is specifically related to a kind of band dust cover horn antenna.
Background technology
During the modern industry level gauging was used, the pulse radar level meter was widely used in level gauging as a kind of contactless radar levelmeter.Principle is that pulse electromagnetic wave is launched via antenna assembly, arrives the measured object surface, and is received by antenna in the measured object surface reflection.Just can calculate instrument to the distance between the measured object surface by transmitting and receiving the electromagnetic time difference.Its antenna assembly is as the electromagnetic part that transmits and receives, and influence transmits and receives the power of signal, has determined whether instrumentation is normal.In measuring process, environmental condition can produce certain influence to it, when the part measured medium has volatilization, crystallization or environment when dust is arranged, coagulation or dust can adhere on oscillator, during electromagnetic wave process oscillator, just can reflect by the adhesion layer on oscillator, make electromagnetic wave normal transmission not arrive the measured object surface, influenced electromagnetic emission, made measurement influenced.
The utility model content
The utility model has overcome deficiency of the prior art, provides a kind of measurement effect good horn antenna.
The technical solution of the utility model is:
A kind of band dust cover horn antenna is characterized in that, comprises oscillator, horn-like antenna, dust cover and clip, and dust cover is fixed on the horn-like antenna with clip.
Compared with prior art, advantage of the present utility model:
The utility model is by adding the mode of dust cover, intercepted dust, the volatilization coagulation directly contacts with oscillator.Thereby the signal transmission attenuation problem that also causes with regard to the attachment of having avoided around oscillator, forming.And the existence of dust cover directly deposits coagulation or dust on radome, because the space is big, sedimentary deposit is thin, and electromagnetic wave just relatively easily penetrates, and reaches the effect of measurement.
Description of drawings
Fig. 1 is the profile of the utility model band dust cover horn antenna.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
With reference to figure 1, the utility model comprises oscillator 1, horn-like antenna 2, dust cover 3 and clip, and dust cover 3 relies on clip to be fixed on the horn-like antenna 2.
More than by specific embodiment band dust cover horn antenna provided by the utility model has been described, it will be understood by those of skill in the art that in the scope that does not break away from the utility model essence, can make certain deformation or modification to the utility model; Its preparation method also is not limited to disclosed content among the embodiment.
