中文摘要:提出了一种基于非色散红外原
理的冰醋酸红外气体传感器。介绍了冰醋酸红外气体传
感器的原理,然后对其结构设计进行了详细描述,并利用Light Tools
软件对其光路进行了仿真验证,最后获得了冰醋酸红外
气体传感器样机。测试结果表明,该传感器在0~5000 ppm范围内
的测量精度优于±1%F.S.,响应时间(T90)为29 s。这种传感器的光源部分
采用电调制方式,舍弃了传统的红外气体传感器光源部分的机
械斩波结构,进而减小了传感器的体积,提高了稳定性。因此,该传感器
在冰醋酸运输、储存和使用等领域具有广泛的应用前景。 |

Design of a Glacial Acetic Acid Infrared Gas Sensor |

Abstract:A glacial acetic acid infrared gas
sensor based on nondispersive infrared principle is proposed.
The principle of the glacial acetic acid infrared gas sensor
is presented. Then, the structure design of the sensor is
described in detail. The optical path of the sensor is simulated
by using the LightTools simulation software. Finally, the
prototype of the glacial acetic acid infrared gas sensor is
obtained. The test results show that the measurement accuracy
of the sensor is better than ±1% F.S. in the range
from 0 to 5000 ppm. Its response time (T90) is 29 s. In the
light source of the sensor, electric modulation is used and
the mechanical chopper structure in the light source of the traditional
infrared gas sensor is removed. Thus, the volume of the sensor
is reduced and its stability is improved. So, this sensor has
a wide application prospect in the fields of acetic acid
transportation, storage and use etc. |
