摘要

自动化气体传感器表征系统是为精确表征集成或离散气体传感器而设计的。燃气计量和数据采集由计算机控制。气体浓度的校准是通过使用气体分析仪或气相色谱(GC)进行的。该系统已用于表征两种类型的商用气体传感器。因此，当系统首先达到平衡，然后施加加热电流将传感器从室环境温度加热到传感器工作温度时，测量气体传感器的瞬态响应。详细介绍了各种商用气体传感器静态和动态特性的实验结果。

An automated precision gas sensor characterization system

The automated gas sensor characterization system is designed for precision characterization of integrated or discrete gas sensors. Gas metering and data acquisition are computer controlled. Calibration of the gas concentration is carried out through the use of a gas analyzer or gas chromatography (GC). The system has been used to characterize two types of commercial gas sensors. The transient response of the gas sensors is therefore measured when the system first reaches equilibrium and then heating current is applied to heat up the sensor from the chamber ambient temperature to the sensor operating temperature. Details of experimental results for static and dynamic characterization of various commercial gas sensors are presented.
