1.2MHz high-frequency weak magnetic field transmitter


sketch:

GSP301HFA (single axis) and GSP303HFA (three-axis) are magnetic field transmitters designed according to industrial standards for measuring AC high-frequency weak magnetic fields. They have the characteristics of high precision, high resolution, and easy integration, and can meet various complex use environments in industrial production. They can be used for scientific research, laboratories, industry, manufacturing and other users. Typical applications include environmental protection, AC transmission and transformation, transformer AC magnetic field measurement, electromagnetic environment limit evaluation, etc.

GSP301HFA (single axis) and GSP303HFA (three-axis) high-frequency weak magnetic field transmitters induce AC magnetic fields and output analog signals proportional to the magnetic field strength (± 3V). The peak measurement range of AC magnetic fields is ± 150 μ T, and the noise is as low as 4nT@100Hz The linearity is better than ± 1%, and the frequency response range is 20Hz-1.2MHz.

GSP301HFA (single axis) and GSP303HFA (three-axis) can also be customized according to user needs, providing products with customized range, resolution, frequency response, voltage output, and probe shape.
