Summary of the invention
When the utility model is installed and used in order to solve existing vibration cylinder pressure transducer, vibration resistance is poor, self is not with shock absorber, use and bring very big inconvenience to user, user adopts vibration reducing measure in use voluntarily in addition, owing to not understanding sensor construction mechanism and can not effectivelyly reach the problem of effectiveness in vibration suppression, a kind of vibration cylinder pressure transducer of vibration damping integral structure is provided, has can be used for the pressure measxurement of airborne miniaturization air data system and Ground Meteorological, pressure checking is measured.
The utility model adopts following technical scheme to realize:
A kind of vibration cylinder pressure transducer of vibration damping integral structure, it is characterized in that involving vibrations cartridge module, signal-processing board assembly, end-cap assembly, vibration isolation rubber, adapter plate for circuit, positioning ring and urceolus composition, vibrating barrel assembly adopts the vibrating barrel assembly of 9mm, vibrating barrel assembly outside is mounted with vibration isolation rubber, positioning ring and lower positioning ring are installed on the vibrating barrel at vibration isolation rubber two ends, the outside sheathed urceolus of positioning ring, lower positioning ring bottom mounting circuit keyset, signal-processing board assembly is fixed by insulator wire bonds, be installed on end-cap assembly, the lead portion of the transducer electrical component of vibrating barrel assembly is welded and fixed by annular adapter plate for circuit, and adapter plate for circuit is connected by wire with signal-processing board, end-cap assembly and urceolus are connected and fixed by welding,
On upper and lower positioning ring, have passage, have gas channel on vibration isolation rubber, the gas circuit of sensor arrives in the atmospheric pressure cavity of vibrating barrel assembly through the passage of the passage of upper positioning ring, the gas channel of vibration isolation rubber, lower positioning ring.
Vibration isolation rubber is outside adopts petal type structure, comprise groove and projection, and groove is gas channel, and projection is connected with urceolus, and vibration isolation rubber inside is anchored on vibrating barrel assembly, being flexible coupling of formation vibrating barrel assembly and urceolus.
9mm vibration cylinder pressure transducer is a kind of product of miniaturization on original 18mm vibrating barrel product basis, do not taking under the prerequisite of vibration reducing measure, about 115mm × 40mm × the 30mm of 18mm vibrating barrel sensor overall structure appearance and size, 9mm vibration cylinder pressure transducer is 52mm × 22mm × 15mm. When use, increase after vibration reducing measure, appearance and size all has increase, and length is all not less than 52mm. The utility model completes as the vibration cylinder pressure transducer with shock absorber based on 9mm vibration cylinder pressure transducer, its appearance and size is diameter phi 25mm × length 48mm, length dimension dwindles, be more suitable for airborne Atmosphere Data Testing System installing space limited, length is had to the environment occasion of requirement, install more simply, more convenient user uses, and range of application is widened greatly. Resistance to shock empirical tests, in the time of power spectral density 0.032g2/Hz, sensor vibration error 0.01%FS, can meet existing airborne products instructions for use.
The relative prior art of the utility model has following beneficial effect: combination product structure and performance characteristics, choose appropriate vibration damping location point, utilize rubber can absorb damping property that vibration transmits to be designed to inside and to be equipped with the product of shock absorber, vibration-proof structure and sensor have been carried out to integrated design, improve the resistance to shock of product self, make user in use without carrying out Vibration Absorption Designing, can directly install and use, user is used more convenient.
