摘要： A sensor comprising a metal heat generating member formed with a heat-resistant insulating coating of Al.sub.2 O.sub.3 or the like over its surface, and an atmosphere-sensitive layer of SnO.sub.2 or the like supported on the coating. The insulating coating is formed, for example, by alumina sol coating and thermal decomposition, or plasma CVD of an aluminum compound. The sensitive layer is formed, for example, by the thermal decomposition of an organic compound of tin, vacuum evaporation or sputtering of tin, or printing of SnO.sub.2 on the heat generating member when the member is in the form of a flat plate. At least one electrode is connected to the sensitive layer for deriving an output from the layer in response to a combustible gas, humidity or the like.

摘要： The hydrogen gas sensor is a catalytic combustion hydrogen gas sensor with a detection element 1, and is characterized by comprising a measuring circuit configured to selectively provide a normal voltage mode for applying a normal voltage to the detection element 1 and a high voltage mode for applying a high voltage higher than said normal voltage to said detection element 1. Thereby, upon energization of the hydrogen gas sensor, the detection element 1 can be first applied the high voltage to be rapidly heated to raise a temperature of the detection element 1 immediately. And then, the detection element 1 can be applied the normal voltage to be heated to be kept at a predetermined temperature at which the hydrogen gas is detected.
摘要翻译：氢气传感器是具有检测元件1的催化燃烧氢气传感器，其特征在于包括测量电路，其被配置为选择性地提供用于向检测元件1施加正常电压的正常电压模式和用于施加的高电压模式高于所述检测元件1的所述正常电压的高电压。由此，在氢气传感器通电时，可以首先对检测元件1施加高电压以进行快速加热，以立即升高检测元件1的温度。然后，可以将检测元件1施加正常的待加热电压以保持在检测氢气的预定温度。
