The utility model provides a composite sensor is integrated on a rectangular shape PCB board with the three-dimensional sensor of two kinds of techniques and the power supply unit of 2 sensors, has realized the composite sensor that can detect three-dimensional strong magnetic field and three-dimensional weak magnetic field simultaneously, and the range is from 0.1 milli gauss to 10 ten thousand gauss, and the range span is up to 9 powers of 10, more convenient to use.
Description
Technical Field
The utility model relates to a sensor technical field, concretely relates to but compound sensor of simultaneous measurement three-dimensional strong magnetic field and three-dimensional weak magnetic field.
Background
A strong magnetic field refers to a magnetic field of 10 gauss to 3 kilogauss. A weak magnetic field refers to a magnetic field of 0.1 milligauss to 10 gauss. From 0.1 milligauss to 3 ten thousand gauss, the measuring range span is up to the power of 8 of 10, and no magnetic field sensor in the world can have such a large measuring range span currently. At present, customers buy two magnetic field measuring instruments to realize the magnetic field measuring instrument. The two instruments are used for measurement, the operation is complex, the working procedure is complicated, and the purchase price of the product is expensive.
Disclosure of Invention
The utility model provides a measure three-dimensional strong magnetic field and three-dimensional low-intensity magnetic field's combined sensor.
The utility model discloses a realize through following technical scheme: the device comprises a three-dimensional weak magnetic field sensor AK09915C, a three-dimensional strong magnetic field HALL sensor M3DX, a long strip-shaped PCB and a power supply unit. The three-dimensional weak magnetic field sensor AK09915C and the three-dimensional strong magnetic field HALL sensor M3DX are tightly close to each other and welded at one end of a strip-shaped PCB, and the power supply unit is welded at the other end of the strip-shaped PCB to form the composite sensor with a parallel structure.
The width of the long strip-shaped PCB is 6mm, the length of the long strip-shaped PCB is 40mm-500mm, and the length of the long strip-shaped PCB is determined according to the requirements of customers. Welding points of a three-dimensional weak magnetic field sensor AK09915C and a three-dimensional strong magnetic field HALL sensor M3DX are reserved at one end of the strip-shaped PCB. And the other end of the strip-shaped PCB is welded with a power supply unit.
The power supply unit comprises a constant current power supply interface and a voltage stabilization power supply interface. The constant current power supply interface supplies power to the three-dimensional high-intensity magnetic field HALL sensor M3DX, and the voltage-stabilizing power supply interface supplies power to the three-dimensional low-intensity magnetic field sensor AK 09915C.
Through a magnetic field experiment of up to 3 kilo-gauss, the magnetic field of 3 kilo-gauss cannot damage the three-dimensional weak magnetic field sensor AK 09915C. The composite sensor may be used in combination.
The utility model has the advantages that: the composite sensor provided by the invention integrates the sensors of two technologies on one power supply unit, so that the composite sensor capable of detecting an electric field and a magnetic field simultaneously is realized, the two integrated sensors use one power supply, the measuring range is from 0.1 milligauss to 10 ten thousand gauss, the measuring range span is as high as 9 times of 10, and the composite sensor is more convenient to use.
