Abstract
1,184,572. Detecting oxygen. CAMBRIDGE INSTRUMENT CO. Inc. May 12, 1967 [May 24, 1966], No.22103/67. Heading G1N. An oxygen detector comprises two sets of elongate electrodes of different noble metals bridged by an electrolyte of hydrogen saturated conductive liquid wetting the surface of a platelike member of insulating material which the electrodes contact. As shown in Fig. 5, a gold wire 37 and a platinum wire 38 coated with platinum black are wound backwards and forwards between ridges 53, 54 to provide the two sets of electrodes. The plate-like member is made of a mixture of epoxy resin and talc. The detector is mounted within a sealed housing having a gas sample inlet tube 29 and an outlet 29<SP>1</SP> for the gas and any condensed liquids that may collect in annular trough 23. The ends of the electrode wires 37, 38 are wound round leads (19), 20 of gold and platinum respectively. Oxygen content of boiler feedwater. To measure the oxygen content of boiler feedwater, a portion of the water is mixed with hydrogen to produce an atmosphere wherein the quantity of oxygen is proportional to the dissolved oxygen in the feedwater, and this atmosphere is fed to the detector where the oxygen dissolves in the conductive liquid to produce a voltage between the electrodes proportional to the amount of oxygen entering the liquid and the hydrogen will maintain the liquid in a hydrogen saturated condition. Cell with permeable membrane. If the sample gas contains a relatively high amount of oxygen, the sample may be passed through a plastics tube (55, Fig. 8 not shown), through the walls of which oxygen can permeate to the detector. In this case, the hydrogen could be supplied directly to the detector or may be mixed with the sample gas.
