The amorphous state alloy sensor probe is characterized in that an amorphous band is filled into the brass framework, the outer layer of the brass framework is thickly wound with a plurality of layers of enameled wire coils, the coils are formed by winding enameled wires with diameter phi equaling to 0.03mm, the receiving coils are about 10000 circles, the component of the amorphous band is Fe(82)B(12)Si(6), the width of the amorphous band equals to 1.5mm, the length of the amorphous band ranges from 30mm to 50mm, and the winding circle number of the amorphous band n equals to 2000cm (-1). The amorphous state alloy sensor probe is relatively small in volume, can overcome shortages of electromagnetic damping of an electromagnetic system which are brought by an electromagnetic inducting sensor and can not be overcome by the same, and has extremely high sensitivity, higher precision and signal-to-noise ratio and fine pressure resistance.
Description
Technical field
The utility model relates to sensor technology, a kind of amorphous alloy sensor probe of more specifically saying so.
Background technology
Sensor is a kind of pick-up unit, usually form by sensitive element and conversion element, can experience measured information, and the information that detection can be experienced, be for conversion into the information output of electric signal or other desired forms according to certain rules, to satisfy requirements such as transmission of Information, processing, storage, demonstration, record and control, it is a primary link of realizing detection automatically and automatic control.And there is following defective in present widely used electromagnetic induction sensor, the firstth, and response frequency is not high, in real life and work, need to know high-frequency information under many situations, but the frequency response of sensor does not catch up with; The secondth, can't overcome electromagnetic damping, such sensor can't satisfy user's needs to a great extent, makes troubles to live and work.
Summary of the invention
The purpose of this utility model provides the less amorphous alloy sensor probe of a kind of volume simple in structure, can overcome the electromagnetic damping of the electromagnetic system that self can't overcome that electromagnetic induction sensor brings, show high sensitivity, its precision and signal to noise ratio (S/N ratio) are higher, and good pressure-resistant performance.
According to the barkhausen on the electromagnetics, be that ferromagnetic material is in magnetic history, when outfield strength reaches certain intensity, the neticdomain wall interface begins to be moved, its the most significant variation occurs in the steepest district of magnetization curve, the magnetic history of this moment is discontinuous, but carry out with the form of transition, when being applied with an alternating electromagnetic field H near the probe of sensor, by Faraday's electromagnetic induction law as can be known, in the probe coil of sensor, will there be induced potential to produce, in the amorphous ribbon of sensor probe, have produced Barkhausen's jump, corresponding barkhausen has also just been arranged.So, when electromagnetic field whenever carries out the one-period variation, in the probe coil of sensor, just have the change of magnetic flux, because the difference of change direction, thereby in probe coil, can produce identical two the generating positive and negative voltage pulses of amplitude shape.The change frequency of electromagnetic field is low more, and the amplitude of output signal is also more little, and noise is also big more; The change frequency of electromagnetic field is high more, the amplitude of output signal also more greatly and very stable, noise is also little, we just can be from the magnetic field situation the output signal perception probe surrounding environment like this.
The purpose of this utility model can realize in the following manner: a kind of amorphous alloy sensor probe, include hollow circular cylinder brass skeleton and the brass bolt that is used for fixing probe, be characterized at the inner amorphous ribbon of filling of brass skeleton, outer close around multilayer at the brass skeleton with enameled wire loop, coil forms with the enameled wire coiling of diameter of phi=0.03mm, receiving coil is about 10000 circles, and the composition of amorphous ribbon is Fe

The utility model compared with prior art has following advantage:
1) temperature is fine, even also can operate as normal under the environment temperature about 125 ℃;
2) shape is little, and is easy to carry, can survey the information of small space;
3) signal to noise ratio (S/N ratio) height is for the quick response greater than the cutoff frequency signal of several KHz;
4) good pressure-resistant performance, can be under the hyperbaric environment of 30MPa steady operation;
5) sensitivity is high, and it has overcome the electromagnetic damping of the electromagnetic system that self can't overcome that electromagnetic induction sensor brought;
6) and related manufacturing process simple, with low cost, be easy to promote.

6Amorphous magnetic hysteresis telescopic band is heat-treated, and a half thickness is a shell of tension in the band of handling, and half is a shell of compression, promptly obtains a dual stressed layers band.
A kind of amorphous ribbon alloy sensor probe by present embodiment provided, the lead-in wire by enameled wire loop obtains detection information.Because its plurality of advantages such as high sensitivity make this sensor be used for turbo flow meter, can reduce the startup discharge capacity that reduces liquid greatly, thereby solved the problems of measurement of low discharge, late period is developed remaining oil, low pay sand and the detection exploitation of oil sheet in oil field for this and effective utilization of water resource has profound significance.
