誘導形ナトリウムレベル計。[Claims for Utility Model Registration] 1. A primary coil wound coaxially and excited by a high-frequency power source, a secondary coil that generates a level AC signal, and two tertiary coils installed above and below the sodium level. The sodium level is calculated by processing the output signals of a detector consisting of a coil, an AC-DC converter that converts the secondary coil signal from AC to a DC level signal, and a temperature signal generator that generates the DC level signal and the sodium temperature signal. In an induction type sodium level meter equipped with a level signal calculation circuit as a signal and an output circuit that converts the level signal into a predetermined electrical output signal, the output signal of the AC amplifier that amplifies each tertiary coil signal is AC-DC converted. This is an inductive sodium level meter that is characterized by the ability to perform online calibration by inputting information by switching to the device. 2 In paragraph 1 of claims for utility model registration, when the number of turns of the secondary coil is N2 and the number of turns of the tertiary coil is N3,
An inductive sodium level meter characterized in that the amplification factor G of the AC amplifier is G=P.
