PURPOSE:To simplify the circuit of a device by providing a catalyst electrode as a positive electrode, a lead electrode as a negative electrode and an electrolyte and an oxygen permeable septum as a detection surface for a dew condensation state. CONSTITUTION:This sensor consists of the catalyst electrode 23 which is effective as the positive electrode to the reduction of oxygen in air, the lead electrode 25 functioning as the negative electrode and the electrolyte 24 and the oxygen permeable septum 22 with which the catalyst electrode 23 is united. This oxygen-lead galvanic battery utilizes large variation in the output value of the battery due to dew condensation on the diaphragm surface. This sensor is basically a galvanic battery, so the sensor itself has a DC output and no external electric circuit is required specially for driving. Consequently, the number of components in use is reduced extremely and the power consumption is reducible. |
