一种抗温度、基线漂移的气体传感器系统及使用方法
摘要：
本发明提供了一种抗温度、基线漂移的气体传感器系统及使用方法，包括电源、电路、第一气体传感器和第二气体传感器；所述第一气体传感器和所述第二气体传感器串联设置在所述电路内；所述第一气体传感器和所述第二气体传感器均为电阻式气体传感器且特性一致；所述第一气体传感器放置在开放气体环境中；所述第二气体传感器外设有覆盖封闭所述第二气体传感器的气罩；其有益效果在于：利用分压原理对传感器系统进行补偿，这样的补偿方式操作简单、静态和动态的补偿效果出众，且无需再对传感器进行软件修正，操作方便，降低成本。
摘要（英）：

The invention provides a gas senor system with resistance to temperature and baseline drift and a using method thereof. The gas senor system comprises a power supply, a circuit, a first gas sensor anda second gas sensor, wherein the first gas sensor and the second gas sensor are connected with each other in series in the circuit; the first gas sensor and the second gas sensor are resistance typegas sensors and are consistent in features; the first gas sensor is arranged in an open gas environment; the second gas sensor is externally covered with a gas cover for sealing the second gas sensor.The gas senor system has the beneficial effects that a voltage dividing principle is used for compensating the sensor system, the compensation manner is simple to operate and excellent in static anddynamic compensation effects, the sensors do not need to be corrected by software, the operation is convenient, and the cost is reduced.
