Title:
CONTROLLING METHOD AND ITS APPARATUS FOR MULTIPOINT SAMPLING VALUES
Document Type and Number:
Japanese Patent JPS5831412
Kind Code:
A
Abstract:
PURPOSE:To perform highly accurate and stable control by successively executing sampling from plural points and then controlling operational points prepared in accordance with respective points after ending each smapling period. CONSTITUTION:In a measuring point M1, a signal is outputted from a control circuit 8 to a detecting valve V1 and, after opening the detecting valve V1, atmospheric gas is discharged from the inside of a furnace to a CO2 analyzer 2 through a CO analyzer 1 and these measured results are inputted to an operation circuit 5 through A/D converters 3, 4, respectively. The operation circuit 5 calculates a carburizing factor, its data is sent to the control circuit 8 and a control valve VC1 is controlled to adjust the carburizing factor of the measuring point M1 to an objective value. After that, same control is applied to measuring points M2-Mn successively.
