The single-dimensional weak magnetic field sensor AK8961 and the single-dimensional strong magnetic field HALL sensor HE244 are tightly close to each other and welded at one end of a long-strip-shaped PCB, and the power supply unit is welded at the other end of the long-strip-shaped PCB to form the composite sensor with a parallel structure. The utility model provides a composite sensor is integrated on a rectangular shape PCB board with the one-dimensional sensor and the power supply unit of two kinds of techniques, has realized the composite sensor that can detect one-dimensional high-intensity magnetic field and one-dimensional low-intensity magnetic field simultaneously, and the range is from 0.1 milli gauss to 3 ten thousand gausses, and the range span is greater than 8 powers of 10, more convenient to use.
Description
Technical Field
The utility model relates to a sensor technical field, concretely relates to but combined sensor of simultaneous measurement unidimensional strong magnetic field and unidimensional 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 compound sensor in single-dimensional high-intensity magnetic field and single-dimensional low-intensity magnetic field.
The utility model discloses a realize through following technical scheme: a single-dimensional weak magnetic field sensor AK8961, a single-dimensional strong magnetic field HALL sensor HE244, a strip PCB board and a power supply unit. The single-dimensional weak magnetic field sensor AK8961 and the single-dimensional strong magnetic field HALL sensor HE244 are tightly close to each other and welded at one end of a long-strip-shaped PCB, and the power supply unit is welded at the other end of the long-strip-shaped PCB to form the composite sensor with a parallel structure.
The width of the strip-shaped PCB is 5mm, the length of the strip-shaped PCB is 50mm-400mm, and the length of the strip-shaped PCB is determined according to the requirements of customers. One end of the long strip-shaped PCB is provided with a welding spot of a single-dimensional weak magnetic field sensor AK8961 and a single-dimensional strong magnetic field HALL sensor HE 244. 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 single-dimensional high-intensity magnetic field HALL sensor HE244, and the voltage-stabilizing power supply interface supplies power to the single-dimensional low-intensity magnetic field sensor AK 8961.
Through a magnetic field experiment of 3 kilo-gauss, the magnetic field of 3 kilo-gauss can not damage the single-dimensional weak magnetic field sensor AK 8961. 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 3 ten thousand gauss, and the measuring range span is more than 9 times of 10, so that the composite sensor is more convenient to use.
