Introduction of Gausometer Probe of Hunan Yongyi Technology Co., Ltd.: At present, FE-102 handheld Gausometer FE-103 desktop Gausometer FE-105 Digital Gausometer Probe is divided into horizontal probe and vertical probe:

GaussiometerThe length of the probe package

　　 GaussiometerThere is no strict limit on the length of the probe package. The theory is determined according to the user's usage. However, there are also certain principles for determination. For example, the probe requires thin and ultra-thin, so the package length cannot be long, and it should be possible within 100mm, If the rear probe, 200-500 package length is also no problem.

　　 GaussiometerIntroduction of various probes:

1. Gaussmeter GaAs probe has the characteristics of small package size, good magnetic linearity, good consistency and small temperature drift.

2. The smaller the diameter of the Gaussmeter axial two-dimensional probe and the axial three-dimensional probe, the better, and the more accurate the test.

3. Hall probe is the key component for making Gaussmeter (Teslava meter), which determines the performance and quality of Gaussmeter (Teslava meter).

4, gaussmeter gallium arsenide sensor, the size of the test sensitive area becomes the key, the smaller the magnetic intensity test calculation is more accurate.

5. The magnetic linearity of GaAs sensor is the lifeline of Gaussmeter measurement accuracy, and the linearity of 0-3T full scale can be maintained at 0.2 excellent level. Temperature drift <0.03%/℃.

6. The packaging process and size of the probe are the key to the performance of the Gaussmeter. Due to the large magnetic attenuation gradient, the closer it is to the magnetic signal, the accuracy can be guaranteed.

7. The smaller the unbalanced voltage, the better. Since the Hall sensor is a bridge device with a four-terminal equivalent circuit, any one of the four arms of the bridge has a slight deviation, which will cause the bridge to be unbalanced. Voltage or offset voltage.
