CONDUCTIVITY METER AND METHOD FOR CORRECTING MEASUREMENT SETTING INITIAL STATE AND CALIBRATION OF CONDUCTIVITY METER

摘要

In the present invention, by accurately obtaining the temperature of the annular magnetic body, the measurement conductivity obtained by the measurement unit is corrected for each temperature of the annular magnetic body, and the electrical conductivity is measured with high accuracy. The primary coil 31 and the secondary coil 32 ), the primary-side magnetic material 21 on which the primary coil 31 is wound, and the secondary-side magnetic material 22 on which the secondary coil is wound, and a power supply unit 5 for applying an alternating voltage to the primary coil 31. , In the conductivity measuring system 100 having a measuring unit 6 for measuring conductivity from the induced current generated in the secondary coil 32, at least one of the primary magnetic body 21 or the secondary magnetic body 22 And a temperature sensor 45 for measuring the temperature directly or indirectly.
