Abstract
The utility model discloses an assembly quartz resonant sensor which is mainly used for measuring the pressure of the field of petroleum geology. The utility model is characterized in that a quartz resonance bare chip (4) is hermetically arranged in the space of the upper body (2) and the lower body of the assembly quartz resonant sensor; the quartz resonance bare chip (4) is connected with an electrode (1). The utility model has the advantages of simple structure, low cost, convenient use and high precision, and the utility model can completely replace imported products and can save large funds.
Description
The utility model is mainly used in the pressure survey of oil geology field to oil, well etc.
The quartz resonance sensor is existing in the world to be used, but manufacture difficulty is big, the cost height, as a kind of quartz electronic pressure gauge that hewlette-packard is produced, Sensor section is to adopt the monoblock quartz crystal to make, and the manufacturing technology difficulty is big, the rejection rate height, though measuring accuracy is higher, involve great expense, use trivial operations, inconvenience.
The purpose of this utility model be to make a kind of simple in structure, easy to manufacture, cost is low, easy to operate, reach the sensor of the high a kind of novelty of measuring accuracy; Adopt the resonance nude film of existing quartz resonator, be assembled into the quartz resonance sensor with metallic elastic component.
The utility model is achieved in that the pressure that utilizes quartz crystal---the load cell of frequency shift effect detected pressures amount, it mainly is installed in the housing of sensor by the quartzy nude film of resonator, and compositions such as locating piece and electrode are housed.Wherein quartzy nude film is the pressure of this sensor a---frequency translation components, when external force acted on the resonator nude film, it self resonance frequency changed, and being in proportion of this variable quantity and external force, the resonance piece surface is coated with electrode layer, links to each other with sensor upper body electrode; The sensor upper body is the support member of quartz resonance sheet, and design has resonance piece to set upright pawl and electrode mounting hole, and the stress when reducing work is concentrated, and inner top is that spherical structure is best; The sensor lower body is the elastomeric element of sensor, and it passes to the quartz resonance sheet with the external force linearity, and closely cooperates with the pawl of setting upright of sensor upper body, to guarantee resonance piece and to set upright pawl and the elastic sensation casting die is connected and fixed; Electrode is a conducting metal, with the sensor insulation, is sealed in the electrode hole of sensor upper body, and links to each other with the quartz resonator electrode with lead; Locating piece is that the axial location of quartz resonator nude film is adjusted piece, is made by insulating material.
Owing to adopted the resonance nude film of existing quartz resonator, solved the quartz crystal processing difficulties, the subject matter that involves great expense, both kept the high precision of test, and simple in structure, easy to manufacture, it is convenient to use again; Price only is equivalent to 1/10th of import instrument of the same type, and economic benefit is obvious, and is popular with users greatly.
Further specify below in conjunction with accompanying drawing, accompanying drawing is the structural representation of assembled quartz oscillating type sensor, mainly be that quartz resonance nude film (4) is sealed in the space of upper body (2) and lower body (6), quartz resonance nude film (4) is connecting electrode (1), electrode (1) is sealed in the electrode hole of sensor upper body (2), and insulate with upper body (2), being connected to lead on the electrode (1) links to each other with quartz resonance nude film (4), it bears the function that exciting current transmits and resonance frequency spreads out of, the outer plating of quartz resonance nude film (4) one deck conducting film.What there was a resonance nude film sensor upper body (2) sets upright pawl (7), sets upright pawl (7) root and is shaped on the boss scalariform; Quartz resonance nude film (4), locating piece (3) and (5) are contained in setting upright in the pawl (7) of upper body (2) simultaneously, and the outside of setting upright pawl (7) is connected cooperation with sensor lower body (6), cooperate with the connection that guarantees upper body (2) shell, nude film (4), lower body (6).Last upper body (2) and lower body (6) connect as one.Locating piece (3) and (5) are the insulator of loop configuration, prevent that quartz resonance nude film (4) from contacting with lower body (6) end face with upper body (2), makes quartz resonance nude film (4) be fixed as the best with axial location in sensor.Quartz resonance nude film (4) is the book rod structure, end face is coated with electrode layer, after the energising, the quartz resonance nude film carries out stable concussion, external force is to set upright pawl (7) to quartz resonance nude film cylinder by what lower body (6) was delivered to upper body (2), the variation that its resonance frequency takes place, its variable quantity and external force are proportional.Sensor lower body (6) profile is a column construction, and the bottom is a sphere shape, is connected to cooperate and is one with the pawl (7) of setting upright of upper body (2).Quartz resonance nude film (4) is sealed in the space of sensor upper body (2) and lower body (6); The space of sensor can vacuumize formula and fill with inert gas and protected, further like this stability and the ageing resistance that has improved this sensor.
It is to pass to quartz resonance nude film (4) by sensor housing that the pressure of being surveyed changes, and sensor directly converts the variation of reservoir pressure to frequency change, arrives ground by current delivery.
