Production of microcomputer magnetometer

Microcomputer magnetometerModel: H31097

Microcomputer magnetometer The "total field magnetometer" is a new type of magnetometer controlled by computer intelligence based on the principle of magnetic flux gate, mainly used for iron ore exploration. It can measure the total field strength T or vertical component Z of the magnetic field. Due to its simple operation, the magnetometer can be learned to use in just a few minutes. The large LCD screen can directly display the measured magnetic field strength nT (gamma code), as well as temperature, date, and battery level (instrument battery), making it suitable for beginners to use. Due to its built-in computer, automatic linear correction, automatic temperature correction, 24 bit high-precision A/D converter, and the ability to measure strong magnetic fields up to 80000 newtons, the magnetometer is also suitable for professional geophysical and geological personnel. The large screen display can display the magnetic field intensity curve, which is convenient and intuitive. When connected to a computer, it can further process and interpret data. Therefore, this magnetometer is easy to operate, high-resolution, and high-precision, and has a high cost performance ratio.

The main functions and purposes of the instrument

This instrument is mainly used for iron ore exploration on the ground. It has the following functions:

1. Multi parameter measurement: Measure the total field strength T or the vertical component Z of the magnetic field.

2. Directly display outliers: Under the premise of measuring baseline values, directly display the outliers of the total fieldOr outliers in the vertical component.

3. Automatically generate curve chart: After the completion of the magnetic survey of the measuring line, it can be displayed(Outliers of the total field) orA curve graph of abnormal values in the vertical component, used to indicate the location of the ore body.

4. Data storage: Automatically store the base point values and magnetic measurement data of measurement points, storing 5000 measurement points, which can be connected to a computer through a data transmission interface. All data can be transmitted to the computer for further analysis and storage.

5. Easy to operate: The fully Chinese operation interface is easy to learn and understand, with convenient operation and backlight display function, which is also suitable for use in poor lighting conditions.

6. Large dynamic range: 24 bit A/D conversion, dynamic range up to 144 dB, magnetic field strength measurement range -80000 nT~+80000 nT, suitable for magnetic prospecting at any location.
