试验条件。紫外传感器响应恢复时间是指在试验条件下,从检测器接触被测气体至达到稳定指示值的时间。通常,读取达到稳定值90%的时间作为响应时间,即常见的T90。紫外线传感器是传感器的一种,可以利用光敏元件通过光伏模式和光导模式将紫外线信号转换为可测量的电信号。
The response/recovery time (tres/trec) are defined as the time taken by the gas sensors to obtain the resistance value changes ranging from Ra to Ra − (Ra − Rg) × 90% and from Rg to Rg + (Ra − Rg) × 90% under the conditions of target gas and air atmosphere, ...
