PURPOSE:To check the soundness of a probe and a control unit, by providing a means generating mimic signals in which the relation between the exciting condition of the primary coil and the output of the secondary coil, the relation between the input and output of the control unit and the relation between the output of the secondary coil and temperature are standardized. CONSTITUTION:The titled device is provided with a means generating mimic signals in which the relation between the exiting condition of the primary coil (not shown in figure) of the probe 11 and the output of the secondary coil (not shown in figure), the relation between the input and output of the control unit 12 and the relation between the output of the secondary coil and temperature are standardized, as well as a digital multimeter 22 and a megger 23 for superhigh insulation resistance. Consequently, the soundness of the probe 11 and the control unit 12 can be checked and calibrated safely, easily and rapidly under the condition that the probe 11 of the induction type sodium level meter is fitted to a plant. |
