Design  of  Magnetic  Signal  Detection  Sensor

Abstract: In the context of the new materials technology and circuit integration in the country, the industry 4.0 is rapidly carrying out, and industrial intelligence is indispensable is the sensor, especially the small integration of the Hall sensor is more greatly promoted the industrial intelligent This paper mainly describes the principle of magnetic signal detection device. And on the basis of the probe in the Hall sensor for its high temperature defects made a theoretical improvement, and the supporting software to learn, micro-programmable processor programming to learn. And the magnetic memory nondestructive testing of this new technology, the specific principles and methods are described. In this design, a temperature compensation circuit is designed and the resistance in parallel with the Hall element is replaced by a temperature resistance resistor for the defect that the output signal of the Hall sensor is affected by the large temperature change. Making the temperature for the Hall sensor interference to a minimum. 

Key words: iron powder nondestructive testing; magnetic memory detection; Hall principle; magnetoresistive principle
