4 working principle

THA3120 Magnetic Mechanical Oxygen AnalyzerUtilizing the paramagnetism of oxygen,And the physical property of high magnetic susceptibility is used to measure the oxygen content in mixed gases. During the measurement process, the gas being measured is introduced into a built-in magnetic field, where oxygen molecules move in the direction of the magnetic field, generating thrust on the suspended dumbbell ball and causing it to deflect. The higher the oxygen content, the greater the deflection. By measuring the deflection of the dumbbell ball, the oxygen content in the measured gas can be determined. The deflection of the dumbbell ball is caused by a closed-loop photoelectric device that generates a reset current on the coil wound around the dumbbell ball to reset the dumbbell. The magnitude of the reset current reflects the deflection of the dumbbell ball and is proportional to the concentration of oxygen.
