Title: Oxygen density controller
Inventor: MORIMOTO YUKO
IPC: G05D21/00
Filed: 1988-06-23
Abstract: PURPOSE:To accurately keep the prescribed oxygen density by measuring and monitoring the diluted/mixed gas via an oxygen density sensor and controlling the flow rate of the unmixed gas so as to keep a fixed level of the density signal output. CONSTITUTION:A PID (proportion, integration and differentiation) controller 12 produces a control signal for the optimum control coincident with the overall response speed of a feedback system via a PID arithmetic operation. This control signal is supplied to the flow rate control valves 2 and 5 of an O2 gas line 1 and a diluted gas line 4 respectively as the complementary forward and reverse action signals through a signal converting circuit and a subtraction circuit. Both valves 2 and 5 change competitively the gas flow rates of both lines 1 and 4 with the valve opening amounts corresponding to the control input so that the sum of the gas flow rates of both lines are kept at a fixed level. Thus the density of oxygen is kept at a set level. As a result, the oxygen density value can be optionally set and kept accurately and stably with a fixed flow rate for supply of the oxygen nitritive gas.
