Abstract
The utility model provides a kind of baroceptor, including shell, terminal；Terminal is set to the outside of shell；Sliding variable resistance mechanism, pressure sensitive film are equipped in shell；The sliding variable resistance mechanism includes two binding posts, slide plate, resistance wire, metallic rod and insulation porcelain cylinder, and resistance wire is wound on insulation porcelain cylinder, and two binding posts are respectively arranged at one end of metallic rod and resistance wire；Pressure sensitive film is located at the right side of sliding variable resistance mechanism, and connecting rod is connected between surface and slide plate；Pressure sensitive film is fixed on the inner wall of shell, constitutes sealing space with the shell on the left of it；Air inlet is offered on shell on the right side of pressure sensitive film；Two binding posts pass through conducting wire respectively and connect terminal.Pressure change makes sense film, and deformation occurs, drives the slide plate of sliding variable resistance mechanism mobile, so that the resistance for sliding variable resistance mechanism is changed, terminal can be circumscribed with power supply, signal handling equipment etc., therefore, can judge air pressure by electric signal；The structure is sensitive to pressure change, and detection accuracy is high.
Description
Technical field
The utility model relates to sensor design technical fields, and in particular to a kind of baroceptor.
Background technique
Baroceptor is the instrument for measuring the absolute pressure of gas, is primarily adapted for use in object relevant to gas pressure intensity
Reason experiment, such as gas law, can also measurement drying, non-corrosive gas pressure intensity in biological and chemical experiment.
Existing baroceptor is many kinds of, and performance is each has something to recommend him, but the biography suitable for monitoring air pressure high-pressure air pipe
The problems such as sensor is few, and there is installation inconvenience, is easily damaged, and detection accuracy is not high.
Utility model content
In view of the above shortcomings of the prior art, the utility model provides a kind of baroceptor, conveniently installs and uses, volume
It is small and exquisite, space is saved, especially facilitates and is used in pipeline monitoring.
To achieve the above object, the utility model adopts the following technical solution：
A kind of baroceptor, including shell, terminal；The terminal is set to the outside of shell；It is described outer
Sliding variable resistance mechanism, pressure sensitive film are equipped in shell；The sliding variable resistance mechanism includes two binding posts, slide plate, resistance wire, metallic rods
With insulation porcelain cylinder, the resistance wire is wound on insulation porcelain cylinder, and two binding posts are respectively arranged at one end of metallic rod and resistance wire；
The pressure sensitive film is located at the right side of sliding variable resistance mechanism, and connecting rod is connected between surface and slide plate；The pressure sensitive film is fixed on
The inner wall of shell constitutes sealing space with the shell on the left of it；Air inlet is offered on shell on the right side of the pressure sensitive film；It is described
Two binding posts pass through conducting wire respectively and connect terminal.
Beneficial effect：1, pressure change makes sense film deformation occurs, drives the slide plate of sliding variable resistance mechanism mobile, makes to slide
The resistance of variable resistance mechanism changes, and terminal can be circumscribed with power supply, signal handling equipment etc., therefore, can pass through electricity
Signal judges air pressure；The structure is sensitive to pressure change, and detection accuracy is high；
2, the sliding variable resistance mechanism of the utility model and pressure sensitive film are arranged in shell, and terminal is in the outer of shell
Side, by conducting wire transmit resistance variation, therefore, the volume of baroceptor entirety is reduced, it is not necessary to equipment pass through
Terminal is external, effectively reduces volume, to be suitable for narrow measurement point；And for the pressure duct of sealing, more
It can be very good the size that detection mouth is set on control piper, reduce opening size, avoid gas leakage, or destroy pipeline；
3, the utility model has the advantages of simple structure, greatly simplifies relative to existing sensor production process.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Figure label：1, shell；2, air inlet；3, terminal；4, resistance wire；5, insulation porcelain cylinder；6, pressure sensitive film；7, even

Specific embodiment
Further explanation is done to the utility model with reference to the accompanying drawing.
As shown in Figure 1, the utility model includes shell 1, terminal 3；Terminal 3 is set to the left side of shell 1；Outside
Sliding variable resistance mechanism, pressure sensitive film 6 are equipped in shell 1.Slide the structure that variable resistance mechanism is similar to slide rheostat, including two wiring
Column 12, slide plate 8, resistance wire 4, metallic rod 9 and insulation porcelain cylinder 5, resistance wire 4 are wound on insulation porcelain cylinder 5, and two binding posts 12 are distinguished
It is set to one end of metallic rod 9 and resistance wire 4,8 change in location of slide plate can cause the resistance variations between two binding posts 12.Sense
Press mold 6 is located at the right side of sliding variable resistance mechanism, and connecting rod 7 is connected between surface and slide plate 8；Pressure sensitive film 6 is fixed on shell 1
Inner wall constitutes sealing space with the shell 1 on the left of it；Air inlet 2 is offered on the shell 1 on 6 right side of pressure sensitive film；It is described two to connect
Terminal 12 connects terminal 3 by conducting wire 10 respectively.
In use, gas enters in shell 1 from air inlet 2, pressure-sensitive by the right end insertion under test gas of the utility model
Pressure difference is generated at left and right sides of film 6, leading to pressure sensitive film 6, deformation occurs, drives connecting rod 7 mobile, and connecting rod 7 drives slide plate 8 mobile, makes two
Resistance between a binding post 12 changes, and achievees the purpose that convert variable electrical signal for atmospheric pressure.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
