Abstract
The utility model discloses an MR (magnetic resonance) magnetic-sensitive temperature transducer which comprises a casing. A control circuit, an MR unit, a thermal sensitive ferrite and a permanent-magnet ferrite are arranged inside the casing. The control circuit is connected with the MR unit, and the MR unit is matched with the thermal sensitive ferrite and the permanent-magnet ferrite respectively. The MR magnetic-sensitive temperature transducer has the advantages of long service life, stable and reliable performance, high sensitivity and the like.
Description
Technical field
The utility model relates to a kind of sensor, more particularly, relates to a kind of MR magnetosensitive temperature sensor.
Background technology
Sensor has number of different types, and temperature sensor is one of them.Magnetic temperature sensor in the market utilizes magnet polarity to realize the sensing effect more, and it is had relatively high expectations to putting, and uses dumb.Do not see long service life, reliable and stable, highly sensitive temperature sensor on the market as yet.
The utility model content
Technical problem to be solved in the utility model provides a kind of long service life, stable and reliable for performance, highly sensitive MR magnetosensitive temperature sensor.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of MR magnetosensitive temperature sensor comprises housing; Be provided with control circuit, MR element, temperature sensitive ferrite, permanent-magnet ferrite in described housing, described control circuit is connected with the MR element, and the MR element matches with temperature sensitive ferrite, permanent-magnet ferrite respectively.
The utility model is owing to adopted said structure, by the MR element magnetic field rather than magnetic pole are responded, so as long as the MR sensor can receive certain magnetic flux, its magnetic resistance will change, to impel control circuit to produce a corresponding signal, therefore, the utility model is highly sensitive and stable and reliable for performance, in addition, the utility model long service life.
After the detailed description of reading embodiment of the present utility model in conjunction with the accompanying drawings, it is clearer that characteristics of the present utility model and advantage will become.
