TM9200 Alternating Magnetometer Calibration Device

Frequency Range

45 Hz～1 kHz

Adjust Fineness

0.001%*RG

Short Term Stability

0.01%/min

Optimal Accuracy

± ( 0.03%*RD①+ 0.02%*RG② )

Full Scale Linearity

< 50 ppm

Annual Error Change

< 100 ppm

Load Capacity

500 VA

Protective Function

Open circuit protection, overload protection functions

Power Supply

AC ( 220 ± 22 ) V，( 50 ± 2 ) Hz

Note

RD is the reading value, RG is the range value.

Magnetic Field Range

1 μT～2 mT

Magnetic Field Uniformity

Uniform field within 20 mm is better than 300 ppm

Magnetic Field Linearity

The magnetic field is proportional to the excitation current and has good linearity

Temperature Effect

The coil constant K changes little with temperature, minimizing the influence of temperature.

Coil Average Radius

100mm

Remark

Calibration of alternating magnetometers whose lower limit of the measurement range is less than 3μT should be performed in a shielded cylinder

Temperature Performance

Working temperature: 0°C～50°C

Storage temperature: -20°C～70°C

Humidity Performance

Working humidity: 40%～80% R H; non-condensing

Storage humidity: < 80% R H; non-condensing
