It is a core component in ensuring the stable operation of electronic information systems.

[Application Introduction] SE1022D Dual-Channel Lock-in Amplifier Measuring Hall Effect

The Hall effect is a type of electromagnetic effect. When current passes through a semiconductor perpendicular to an external magnetic field, carriers are deflected, and an additional electric field is generated perpendicular to the direction of the current and the magnetic field, thereby generating a potential difference at both ends of the semiconductor. This phenomenon is the Hall effect. The Hall effect is widely used in material characterization and magnetic field sensing.

Application of SLA-HVP-105 high voltage power amplifier in acoustic-optic synergistic enhancement in deep tissue photodynamic therapy

The SLA-HVP-105 high-voltage power amplifier is used to drive the ultrasonic transducer to generate a high-intensity focused acoustic field, and the scattered light is focused by the acoustic pressure gradient, thereby improving the penetration depth and light energy transfer efficiency of the 660nm therapeutic laser in the bionic tissue model.

Application of Lock-in Amplifier SE1201 in Absorption Spectroscopy

In August 2019, the team of Huang Yinbo and Cao Zhensong successfully used a self-built 3.66μm laser heterodyne radiometer in the Golmud area to obtain the absorption spectra of HDO and H2O in the atmosphere. The average columnar density during the experiment was 1.07 to 1.4g/cm2, and the HDO/H2O ratio in Golmud during the observation period was 163×10-6 to 193×10-6. During the spectral research process, the team of Huang Yinbo and Wu Pengfei optimized the altitude interval in the retrieval process based on the analysis of the altitude grid, and reduced redundant information through the refined altitude layer. At the same time, the study used reverse trajectory analysis to study the relationship between H2O (HDO) density and atmospheric motion, and based on the observation results, it was shown that the origin and path of the airflow can affect the H2O density and isotopic abundance.

Protect safety, start with electromagnetic switch testing!

Insulation resistance testing is an important means of evaluating the insulation performance of electrical equipment. In the absence of magnetic field interference, it can accurately reflect the insulation status of the magnetic switch, ensuring that no electrical accidents will be caused by poor insulation during use, thereby ensuring the safety of personnel and equipment.
