Description
Technical field
The utility model relates to a kind of open loop magnetic flux transducer, belongs to magnetic flux detecting sensor technical field.
Background technology
British scientist joule in 1842, find magnetoelastic effect. in the time that external world's machinery load that ferrimagnet bears changes, its inner magnetization (magnetic permeability) changes, and the magnetic permeability of the member of making by measurement ferrimagnet changes, and measures the internal force of member.
Known magnetic flux quantity detection sensor, is closed loop configuration, and generation need to be inserted in cable wire in advance. but to the cable of having built up, can not test.
Known magnetic flux quantity detection sensor, shortcoming be, for closed loop configuration, need to be in the time building, need to be inserted in advance in cable, can not detect built cable. known magnetic flux quantity sensor, test can not be dismantled after installing, a cable wire just needs a magnetic flux transducer, and material cost is high.
Summary of the invention
In order to overcome above-mentioned defect, the purpose of this utility model is to provide a kind of open loop magnetic flux transducer, and this sensor detects the cable wire of having built up, and many cable wires can use a magnetic flux transducer test.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of open loop magnetic flux transducer, it comprises the sensor construction unit of two symmetrical structures, and in two sensor construction unit, being formed centrally a cross section is open circles structure, and open circles structural formula places that cable wire uses; On described sensor construction unit, be provided with multiple fixed orifices, be provided with temperature sensor in the inside of sensor construction unit;
Described each sensor construction unit comprises open-loop excitation coil and open loop inductive coil.
The wire of described open-loop excitation coil and open loop inductive coil is drawn from the end face of sensor construction unit.
The beneficial effects of the utility model:
The utility model is a kind of open loop structure, is made up of symmetrical two parts, can be combined on cable wire, also can simply take off from cable wire. do not need to be inserted in cable wire and just can carry out magnetic flux Suo Li test to cable wire.
The utility model can reduce the cost of magnetic flux transducer. improve the popularity rate of magnetic flux transducer. and to the hidden troubles removing of bridge, significant.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of sensor construction unit (1) in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of open loop magnetic flux transducer, it comprise two symmetrical structures 1, two sensor construction unit 1, sensor construction unit in to be formed centrally a cross section be open circles structure 2; On described sensor construction unit 1, be provided with multiple fixed orifices 3, be provided with temperature sensor 4 in the inside of sensor construction unit 1;
Described each sensor construction unit 1 comprises open-loop excitation coil 6 and open loop inductive coil 7.
