Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Embodiment one：
Referring to as Figure 1-Figure 5, the technical scheme that present embodiment uses is：It includes body of heater 1, electrode 2；Stove
The inside of body 1 is provided with three electrodes 2；It also includes three measurement apparatus 3；Described measurement apparatus 3 is fixedly connected by screw
On the outside opening of body of heater 1, and each electrode 2 both corresponds to a measurement apparatus 3；Described measurement apparatus 3 is by the He of chip 4
Shell 5 is formed；The outside of chip 4 is connected with shell 5 by non magnetic skeleton；Space between described shell 5 and chip 4 is
Cooling passage 6；Described chip 4 is Hall semiconductor magnetic flux transducer.
Further, described shell 5 is stainless steel casing.
Further, the outside opening of described body of heater 1 is arranged in 90 ° of the center vertical line both sides angular region of electrode 2, and chi
Very little is 60mm × 300mm.
The operation principle of present embodiment：The principle of foundation is Ampere circuit law：Magnetic field intensity=coefficient * conductors
In electric current/conductor outside certain point and the distance of conductor；According to Hall Semiconductor magnetic field sensing principle：The magnetic field of alternation passes through suddenly
You can produce induced electromotive force by semiconductor, and the size of induced electromotive force is directly proportional to by the size of magnetic flux；Due to measuring model
The magnetic flux and electrode current passed through in enclosing is directly proportional, so we assume that electric current is constant（In practical operation electric current be also
Stabilization, has the magnetic flux correction coefficient of different electric currents in computer data, is automatically selected for device in certain limit）, survey
The distance of magnetic flux and distance electrode in the range of amount is inversely proportional, it is necessary to assure the position of measurement point immobilizes, and now measures model
Vertical direction magnetic flux caused by magnetic flux and the electrode of constant current in enclosing and the furnace charge shunt current below electrode tip
In vertical direction magnetic flux have the relation of direct ratio, and flow through electrode tip electric current and be just consumed after furnace charge is contacted and large area
Shunt（Direction is changed）, under causing magnetic flux below electrode tip in the range of corresponding stove external pelivimetry significantly
Drop, then part of the electrode in measurement range more than electrode tip is more, and magnetic flux is bigger, otherwise more than electrode tip
Part of the electrode in measurement range it is fewer, magnetic flux is with regard to smaller.When electrode tip is displaced to above measurement range, magnetic flux
Amount is minimum；When electrode tip is displaced to it is following when, magnetic flux is maximum.Cause the magnetic induction of Hall semiconductor electric by magnetic flux change
The change of gesture, so as to just react the change in location of electrode tip, key is that measurement point position is placed in the work model of rise fall of electrodes
It is in enclosing and adjustable up and down；Measurement point position must be as far as possible close to electrode；Influence to accuracy of measurement, first, other two-phases
The influence of electrode current and change in location, because body of heater material is steel, so most influence is shielded, while another two-phase
Farther out, its influence is also very weak for electrode distance measurement point；Second, the current distributing of the split point of electrode tip and furnace charge is random
Divergence form, shunting effect is not bery stable.
After said structure, present embodiment has the beneficial effect that：It is a kind of powered described in present embodiment
