ことを特徴とするガス検出器用アダプタ装置。[Claim for Utility Model Registration] An input terminal to which the output of a gas detector that outputs a predetermined voltage during normal monitoring and a gas detection voltage higher than the normal voltage during gas detection is connected, and the input voltage of the input terminal. a switching circuit consisting of a transistor and a Zener diode that becomes non-conductive when the output voltage is the normal output voltage of the gas detector and becomes conductive when the gas detection voltage is present, and a capacitor connected in series to a parallel circuit of a resistor and a diode; When conductive, the capacitor is charged according to the time constant determined by the resistor and capacitor in response to the gas detection voltage of the gas detector, and when the switching circuit returns to non-conductive during or after charging, the charging voltage of the capacitor changes. a charging/discharging circuit that quickly discharges the microcapacitor through the diode; a constant voltage from the zener diode of the switching circuit is input as a reference voltage, and a capacitor terminal voltage of the charging/discharging circuit is input as a comparison voltage to calculate the terminal voltage due to microcapacitor charging. A comparator that outputs an output of 5 when the voltage exceeds a certain voltage of the Zener diomide, and a relay that is connected to the output of the comparator and has at least two circuits of relay contacts that are activated by the comparison output. Adapter device for gas detector.
