Abstract The influence of temperature and humidity on the determination of benzene concentration were characterized using a piezoelectric crystal gas sensor. Sensing layers coated with polymethylphenylsiloxane and polyvinylchloride was used for real-time monitoring of benzene, a major atmospheric pollutant. When the humidity was varied from 35% to 75%, the detection limitations of the sensor were reduced and the response and frequency recovery times increased. However, when the temperature was increased from 5 °C to 60 °C, the response and recovery time were decreased but the sensitivity performance was degraded. Models were developed for the correlation between the benzene concentration and temperature and humidity.

温湿度对压电晶体传感器检测苯蒸气的影响

摘要 利用压电晶体气体传感器表征了温度和湿度对苯浓度测定的影响。涂有聚甲基苯基硅氧烷和聚氯乙烯的传感层用于实时监测苯，这是一种主要的大气污染物。当湿度从 35% 变化到 75% 时，传感器的检测限制降低，响应时间和频率恢复时间增加。然而，当温度从 5 °C 增加到 60 °C 时，响应和恢复时间降低，但灵敏度性能下降。建立了苯浓度与温度和湿度之间相关性的模型。
