Abstract
PURPOSE: Whether the bolt on the furnace door is correctly fitted to the bolt receiver on the furnace wall or not, or whether the bolt is completely removed from the bolt receiver or not is detected by signals to assure the results with high accuracy and reliability than by eye observation.
CONSTITUTION: When the furnace door covers the opening and the bolt on the furnace door a is fitted to the bolt reaceiver b1 and b2, the device for determining the reference point of the displacement in the unit for measuring the vertical displacement is lifted along the vertical line R-R' to come into contact with the lower end r of the bolt receiver b1 and the measuring device 2 is made to fall down along the line R-R'. When the one end a1 of the bolt correctly connects to the receiver b1, the variable transformer generates a power corresponding to the distance H between the reference point y1 and the measured point y2. In the horizontal direction, the power corresponding to the distance J between the reference device 39 and the measuring device 41 is also generated, when they are correctly fitted.
