Step 5, coaxial cable ectonexine choose different non-magnetic materials, wherein internal layer is selected than outside low-resistivity
Material.
Preferably, the inner layer material is anaerobic fine copper or silver, cladding material is constantan.
The present invention has the advantages that：
The present invention without magnetoelectricity heating means, by close direction side by side or direction multiple twin combination coaxial cable be heating
Material using around by the symmetrical cabling mode at heating region center, and selects and tested Magnetic Sensor different mode
Power supply mode.Magnetic field will be interfered to reduce several orders of magnitude caused by electrical heating, effectively avoids Magnetic Sensor temperature property test

Description of the drawings
Fig. 1 is flow chart of the method for the present invention；
Fig. 2 is coaxial cable schematic diagram；
Fig. 3 is coaxial cable closely reversed side-by-side configuration schematic diagram；
Fig. 4 is the reversed multiple twin schematic diagram of coaxial cable.
Specific implementation mode
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The electrical heating method without magnetic of the present invention is to heat to carry out temperature characterisitic survey to Magnetic Sensor with this to Magnetic Sensor
Examination, in order to reduce magnetic disturbance caused by even being eliminated electrical heating, uses following method, as shown in Figure 1, being specially：
Step 1 selects coaxial cable as heater strip；As shown in Fig. 2, coaxial cable can theoretically offset whole interference
Magnetic field.Since heating is apart from limited, generally centimetre or decimeter level, practical application standard coaxial cable can also remaining a small amount of magnetic
.
Step 2, as shown in Figures 3 and 4, to coaxial cable carry out it is close reversed side by side or reversed multiple twin mode combines, combine
The major part of remnant field can be offset again afterwards.
Step 3, using the symmetrical cabling mode around tested Magnetic Sensor center, reach and further decrease remanence
The purpose of field.
Step 4, the pattern for selecting electric current：When tested Magnetic Sensor is DC operation pattern, using Alternating Current Power Supply pattern；
When tested sensor is alternate current operation pattern, using direct current supply pattern；Thus the interference magnetic field only remained can be made to avoid being tested
The operating frequency range for trying Magnetic Sensor achievees the purpose that interference magnetic field is avoided to influence.
Step 5, in order to ensure that the thermal stability of coaxial cable at work, coaxial cable ectonexine choose different no magnetic
Material：Internal layer is the anaerobic fine copper or silver of low-resistivity, and outer layer is the constantan of high resistivity, so that it is heated the heat overwhelming majority and makees
Outside for coaxial cable.
By close direction side by side or direction multiple twin combination coaxial cable be heating material, using around by heating region
The symmetrical cabling mode at center, and select the power supply mode with tested Magnetic Sensor different mode.Electrical heating is caused
Interference magnetic field reduce the several orders of magnitude, effectively avoid the electrical heating of the occasions such as Magnetic Sensor temperature property test from interfering magnetic field shadow
It rings.
Embodiment：
The a diameter of Φ 200mm in heating zone that heating coil is formed, totally 10 circle, a diameter of 1mm of heater strip, heated current are
1A.If do not considered no magnetic design, heating coil is about 50 μ T in the magnetic field of heating district center.
By the present invention without magnetic design method, using coaxial heater wire, and closely reversely side by side or after reversed multiple twin combination,
The positive and negative counteracting because of the positive and negative intersection of electric current of most magnetic fields.Because magnetic field and distance are inversely proportional, symmetry is considered, then remnant field
It will be no more than former magnetic field：
The magnetic field of i.e. original 50 μ T will decrease to no more than 2.5nT (0.005%), can be very good to meet nonmagnetic want
It asks.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's
Within protection domain.
