Description
Technical field
The utility model belongs to pressure measurement technology, is specifically related to two remaining pressure sensor structures that a pressure source inlet realizes the measurement of two-way independent pressure.
Background technology
In order to obtain more adequately recording pressure source pressure, traditional single channel sensitive element pressure survey means are often occurring that the inaccurate rear system of this road sensor measurement cannot normally work.If system does not have the force value of related device to sensor measurement to compare in addition, just accurately cannot judge whether sensor output value accurately reflects pressure source pressure.
In the measurement task that some installation sites allow, people usually adopt and install two sensors in close positions, gather two sensors and export the method for averaging to judge pressure source force value.But, adopt measurements of two-way pressure transducer to not only increase the volume of system, and cause the force value difference at two sensor measurement places due to two inconsistent meetings of pressure transducer pressure measurement point, cause system acquisition value and actual value inconsistent.
Utility model content
The purpose of this utility model is: provide two remaining pressure sensor structures that an a kind of pressure source Interface realization two-way independent pressure is measured.
The technical solution of the utility model is: a kind of two remaining pressure sensor structure, it comprises pressure inlet 1, sensitive element 2, resolving circuit assembly 3, power circuit components 4, connector 5, urceolus 6 and support 7, wherein, two independently sensitive element 2 be fixed on pressure inlet both sides inner chamber, resolving circuit assembly 3 is two, be arranged on two other side of pressure inlet respectively, support installing is at pressure inlet rear end face, power circuit components 4 is two, be arranged on support both sides respectively, urceolus is enclosed within outside support, and coordinate with pressure inlet rear end, outer tube rear end is fixed on support simultaneously, connector 5 to be arranged on support 7 through outer tube rear end and to be connected with power circuit components.
A pressure-sensing device, a resolving circuit assembly and mutual wiring of power circuit components form the pressure transducer of a single remaining.
Described support is I shape engraved structure.
The utility model has the advantages that: the utility model pressure source pressure arrives two sensitive element pressure-sensitive parts by pressure inlet tracting pressuring hole, sensitive element pressure-sensitive exports corresponding electric signal, and resolving circuit resolves it, exports desired value.Measure the pressure source pressure that tracting pressuring hole is introduced, two-way is measured respectively and is resolved simultaneously, has both realized two remaining and has measured and resolve, again can comparison mutually, and can supporting pressure system, can be used for raising system and judges tonometric accuracy.

In figure, 1 is pressure inlet, and 2 is sensitive elements, and 3 is resolving circuit assemblies, and 4 is power circuit components, and 5 is connectors, and 6 is urceolus, and 7 is supports.
Embodiment
Below the utility model is described in further details.
Please refer to Fig. 1 and Fig. 2, two remaining pressure sensor structure comprises pressure inlet 1, sensitive element 2, resolving circuit assembly 3, power circuit components 4, connector 5, urceolus 6 and support 7.Wherein, two independently sensitive element 2 be fixed on pressure inlet both sides inner chamber, experience the pressure that pressure inlet inner chamber is identical.Resolving circuit assembly 3 is two, is arranged on two other side of pressure inlet respectively, and is communicated with respective sensitive element.
Described support is I shape engraved structure, is arranged on pressure inlet rear end face, and power circuit components 4 is two, is arranged on respectively on support both sides, and is connected with respective resolving circuit assembly respectively.Described urceolus is enclosed within outside support, and coordinates with pressure inlet rear end, and outer tube rear end is fixed on support simultaneously, protects internal component.Described connector 5 through outer tube rear end, and is arranged on support 7, and is connected with power circuit components, realizes the input and output of signal.
A pressure-sensing device in the utility model, a resolving circuit assembly and mutual wiring of power circuit components form the pressure transducer of a single remaining.Two overlap independently pressure transducer introduces pressure source pressure by a pressure interface, built-in two independently pressure-sensing devices, and resolved by the resolving circuit that two-way is separate, reach and realize electric physical isolation in smaller size smaller, reach two tonometric object of remaining.
