3. Application

☆ Calibrating Tesla meters and flux meters

To calibrate the Tesla meter:

1. Output precision excitation current to the electromagnet through a precision DC excitation power supply.
2. Place the precision magnetometer probe of TH8030 and the Tesla meter probe of the magnetometer to be calibrated in the same uniform area of the electromagnet.
3. Compare the two indications to achieve calibration of the Tesla meter.

To calibrate the flux meter:

1. Use the TH8030 built-in volt-second method fluxmeter calibrator to calibrate the fluxmeter of the magnetometer being calibrated.

 

☆ Measuring electromagnet magnetic field non-uniformity

1. The excitation current is output to the electromagnet to be calibrated through the calibrated permanent magnet magnetic detector.
2. Place the precision magnetometer probe of TH8030 at the center of the pole surface of the electromagnet to be calibrated.
3. The host controls the intelligent positioning device of the probe to move the probe slowly to measure the non-uniformity of the magnetic field of the electromagnet.

☆ Measuring the coil constant

1. The excitation current is output to the electromagnet through a precision DC excitation power supply.
2. Place the precision magnetometer probe of TH8030 in the center of the pole surface of the electromagnet.
3. Place the coil to be calibrated in the center of the electromagnet pole surface. After clearing the precision flux meter in the host computer, quickly pull out the coil, record the magnetic flux, and calculate the coil constant.

 

☆ Calibrating magnetic properties parameters

1. Use the reference sample as the load, set the calibration point through the magnetometer to be calibrated, and output the excitation current.
2. Use TH8030 and the magnetometer to be calibrated to simultaneously measure the remanence Br, coercivity Hc, intrinsic coercivity Hcj, and maximum magnetic energy product (BH)_max of the reference sample to achieve calibration of the magnetic property parameters of permanent magnet materials.
