Abstract

PURPOSE: To display the temperature and liquid level on the same display device, by providing a cylindrical body with the bottom isolated from the vessel, a temperature detecting element inserted in it, also a switching circuit which detects conduction between the cylindrical body and the vessel through a conductive liquid, and also a display device.
CONSTITUTION: A stainless steel sheath 27 inserted into the metallic vessel 21 is provided to the regular position, and the liquid surface of a conductive liquid 22 is supposed to be on a level with the liquid level as shown by the two-dot chain line. In this case, since the conductive liquid 22 does not allow to contact with the stainless steel sheath 27, the liquid level detection circuit 33 remains opened, the switching circuit 34 is turned off, and display is not performed to the display device 36. Subsequently, when the liquid is allow to contact with the stainless steel sheath 27 as shown by the full line, the liquid detection circuit 33 is closed, voltage of the supply voltage 32 is lowered by the resistor 31, the switching circuit 34 is turned on, an output of the thermo-electric couple 30 is displayed on the display device 36, and it is shown that the liquid level has become the set point or more at the same time. Accordingly, the number of display device can be decreased to half.
