DX-1000H High Temperature Hall Measurement Setup consists of an electromagnet, a vacuum pump, a high-temperature vacuum chamber, a Gauss meter, a constant current source, an electromagnet current source, a temperature controller, a computer and software.
Working principle of DX-1000H High Temperature Hall Measurement Setup
- The electromagnet current source provides current to the electromagnet to generate a magnetic field;
- The gauss meter measures the value of the uniform magnetic field generated by the electromagnet;
- On the one hand, the constant current source provides sample test current to the sample for Hall effect testing, and on the other hand, it is used to measure the Hall voltage fed back by the sample;
- The sample to be tested is placed in a high-temperature vacuum chamber, fixed by high-temperature glue, and used as four test points;
- There are 4 leads from the high-temperature vacuum chamber, two of which are connected to the temperature controller for temperature measurement and control, the other is the lead wire of the high-temperature probe connected to the Gauss meter, and the other is connected to the Hall sample connection wire to the constant current source ;
- The computer is connected to a gauss meter, a temperature controller, a constant current source and an electromagnet current source, and the software controls the current and magnetic field values passing through the sample being measured, and obtains the measured voltage value.
