Abstract
PURPOSE: To prevent malfunction by preventing the sticking of metal vapor to the insulation section.
CONSTITUTION: A given voltage is fed to the electrode 2 and the contact stylus 4 through the electric cable 1 by the electric power supply 20. The isolation of the electrode 2 with ground is kept with the insulator 5. The liquid metal 10 is grounded through the vessel 12, and the liquid level rises and it touches the contact stylus 4, then the closed circuit is formed and the indication of the ammeter 19 generates the detection signal of liquid level. To prevent the sticking of metal vapor on the surface of the insulator 5, power is fed to the electric heater 8 provided in the heating sleeve 9 and the current flowing to the electric heater 8 is controlled while measuring the temperature with the thermocouple 11, then the periphery of the insulator 5 and the heating sleeve 9 is heated to a given temperature. This temperature set is set higher than the atmospheric temperature including metal vapor, allowing to prevent the sticking of metal vapor to the insulator 5.
