Description
Technical field
The present invention relates to a kind of band filter function high temperature fluid ultrasonic transducer.
Background technology
At present, the ultrasonic flow transducer on the market has various ways, and frequency and size differ, and relative merits are respectively arranged, and it is bigger that the transducing sheet that size is big is measured power ratio, but a little less than the antijamming capability.Above flow transducer is generally open, the shortcoming of this open transducer is poor anti jamming capability, unstable properties, inner transducing sheet contacts with air for a long time, oxidation easily, waterproof ability is poor, and the water inlet back is damaged inner transducing sheet easily, cause the transducing sheet to damage, poor anti jamming capability influence metering.
Summary of the invention
The objective of the invention is to, overcome the defective that existing ultrasonic flow transducer exists, and a kind of ultrasonic flow transducer of new structure is provided, make its stable performance, antijamming capability is strong, measuring accuracy is high, thereby be suitable for practicality more.
The object of the invention to solve the technical problems realizes by the following technical solutions.According to a kind of band filter function high temperature fluid ultrasonic transducer that the present invention proposes, it comprises; Insulator foot, stainless steel metal cap, metal cap covers on the base, be bonded with the transducing sheet in the metal cap, base is provided with annular boss, base, metal cap, boss form the cavity that is used for holding the transducing sheet, are provided with cushion in the annular groove between toroidal inductor, the boss, and the transducing sheet connects two contact conductors by telefault, two contact conductors of transducing sheet stretch out from the fairlead of base, and fairlead is sealed.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
Aforesaid band filter function high temperature fluid ultrasonic transducer, wherein said base are circular high temperature resistant, and its diameter is 25mm, highly is 6.5mm.
Aforesaid band filter function high temperature fluid ultrasonic transducer, wherein said transducing sheet frequency be ± 1MHZ, electric capacity be ± 2000 piezoelectricity ceramics
Aforesaid band filter function high temperature fluid ultrasonic transducer, wherein said metal cap is the stainless steel circle, and metal cap is provided with shade, and its diameter is 21mm, highly for 4.5mm.
The present invention adopts technique scheme, and tool has the following advantages: between lead-in wire and transducing sheet telefault is arranged, antijamming capability is strong, and performance is more stable, has improved measuring accuracy.Base, metal cap construction are reasonable, and it is little to have a volume, high-power advantage.Preferable, between base and metal cap, transducing sheet, sealant is set, have favorable waterproof property.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of instructions, and for above-mentioned and other purposes, feature and advantage of the present invention can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.
