Description
Technical field
The utility model relates to sensor, in particular to a kind of wind pressure sensor.
Background technique
The product (0-500Pa) for detecting wind pressure in fresh air system and water heater currently on the market, mainly uses wind pressure
The mechanical switch such as switch.
When detecting different pressure values, need to be adjusted the operating pressure value of blast switch, it cannot be general.
Utility model content
It is simple, easy to use that the technical problem to be solved by the present invention is to provide a kind of structures, can real-time detection go out
The wind pressure sensor of test environment apoplexy pressure pressure value.
In order to achieve the above objectives, the technical solution of the utility model is as follows:
A kind of wind pressure sensor, including shell, shell are made of pedestal and upper cover；The interior of shell is equipped with wiring board,
The interior of shell is equipped with the first type chamber and second type chamber being independently arranged, and the first type chamber and outside atmosphere are connected, second type chamber
It is connected with tested wind pressure, the first type is intracavitary to be equipped with the first absolute pressure transducer, and second type is intracavitary to be equipped with the second absolute pressure biography
Sensor, the first absolute pressure transducer and the second absolute pressure transducer are and circuit board electrical connection.
In one embodiment of the utility model, sealed between the first type chamber and second type chamber by gasket.
In one embodiment of the utility model, pedestal and upper cover are fastened togather, and are locked by screw.
Through the above technical solutions, the beneficial effects of the utility model are:
The utility model structure is simple, easy to use, can real-time detection go out the pressure value of wind pressure in test environment.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the utility model section view；
10, pedestal 20, upper cover 30, screw 40, wiring board 50, the first type chamber 60, second type chamber 70, first are absolute
Pressure sensor 80, the second absolute pressure transducer 90, gasket.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Shown in Figure 1, the utility model discloses a kind of wind pressure sensor, including shell, shell is by pedestal 10 and upper
Lid 20 forms, and pedestal 10 and upper cover 20 linked together by snap, and locked by screw 30 (snap this
Place, which is not added, to be repeated, can the similar connection type with card slot in the prior art and fixture block)；Interior of shell is equipped with wiring board
40, wiring board 40 is fixed by way of viscose glue；Interior of shell is equipped with the first type chamber 50 and second type chamber being independently arranged
60, the first type chamber 50 is connected with outside atmosphere, is equipped with the first absolute pressure transducer 70, the first absolute pressure in the first type chamber 50
Sensor 70 is used to measure the pressure value of atmosphere, and the pressure value detected passes to wiring board 40；Second type chamber 60 with
Tested wind pressure is connected, and the second absolute pressure transducer 80 is equipped in second type chamber 60, the second absolute pressure transducer 80 is for surveying
The pressure value of test environment is measured, and the pressure value detected passes to wiring board 40；First absolute pressure transducer, 70 He
Second absolute pressure transducer 80 is electrically connected with wiring board 40.
It is sealed between the first type of the utility model chamber 50 and second type chamber 60 by gasket 90, avoids atmosphere wind pressure and quilt
Surveying crossfire between environment wind pressure influences the detection accuracy of absolute pressure transducer.
The utility model is connected the first absolute pressure transducer using the characteristic of sensor detection Real-Time Atmospheric pressure fluctuation
In atmospheric pressure environment, using the pressure value that it is detected as a reference value, the second absolute pressure transducer is connected to detected
In environment；When the fluctuation of detected environment no pressure, detect that pressure value is identical as a reference value, i.e., wind pressure value is 0Pa；Work as quilt
When detecting pressure oscillation in environment, the pressure difference value of pressure value and a reference value comparison detected is as detected environment
In pressure value；The utility model is compared by the absolute pressure that two absolute pressure transducers detect, to detect
It is tested the real-time change of wind pressure value out and is converted to linear output signal.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
