る酸欠警報器。 An oxygen sensor 6 that utilizes the pumping action of heated stabilized zirconia and a constant monitoring voltage applied across both ends of the oxygen sensor 6, and a conversion circuit A that converts the current flowing through the oxygen sensor 6 into a voltage and a monitoring voltage 2 A switching means 21 for switching between stages, a comparison circuit C for comparing the output voltage of the conversion circuit A, an alarm circuit D for issuing an alarm when the oxygen sensor 6 is abnormal, a control means 20, and a confirmation switch 25 for checking the operation of the oxygen sensor 6. The output of the comparison circuit C and the confirmation switch 25 are connected to the input of the control means 20, and the switching means 21 and the alarm circuit D are connected to the output. It is characterized by having a function of lowering the monitoring voltage by the post-switching means 21 after inputting the voltage, and then driving the alarm circuit D when the output of the comparison circuit C does not cause a decrease in the output of the conversion circuit A after a certain period of time has elapsed. Oxygen deficiency alarm.
