    • PURPOSE: A dissolved oxygen sensor is provided to decrease side diffusion and to improve a rectilinear property for vertically permeating oxygen through an electrode and a performance to a span shift caused by a shock by attaching a spacer of which a side face is more densely formed than a front face. CONSTITUTION: In a dissolved oxygen sensor, a selective permeable film(1) permeates oxygen, used in a macro electrode of dissolved oxygen. An electrode(2) generates a current change according to an amount of the oxygen permeating through the film. A spacer(5) is positioned between the selective permeable film and the electrode.
    • 目的:提供一种溶解氧传感器,以减少侧向扩散,提高垂直透过电极的氧气的直线性能,以及通过将侧面比较密实地形成的间隔件附着在冲击引起的跨度位移上 前脸 构成:在溶解氧传感器中,选择性渗透膜(1)渗透氧气,用于溶解氧的微电极。 电极(2)根据透过膜的氧气的量产生电流变化。 间隔物(5)位于选择性渗透膜和电极之间。

    • An oxygen sensor comprises an ellectrically conductive substrate (I) and electrolytic oxydative polymeric membrane (II) coating a surface of (I), (II) comprising at least one substance selected from porphyrin cpds. and metal complexes of porphyrin cpds. Pref. (I) is ellectrically conductive carbon, and porphyrin cpds. are hydroxy aromatic derivs.-substd. or amino aromatic derivs.-substd. porphrin cpds. at meso position. The PO2 (mmHg) reducing current correlation exhibits good linearity at a constant temp.. Ths enables the PO2 concn. to be measured from this calibration curve. The sensor has excellant selectivity to oxygen due to no interfering substance.
