Abstract
Description
図1と図2に示すように、本実施の形態における微粒子検知装置は、照射した光の散乱による反射光の強度に基づき、空気中に存在するホコリの大きさに応じたパルス状となる電圧信号を出力する微粒子検知手段1と、前記電圧信号を読み取り、単位時間当りの信号の発生量から空気中のホコリ量を判定する判定手段2から構成している。
2 判定手段
Claims (1)
- 照射光の散乱による反射光の強度に基づき、空気中に存在するホコリの複数の粒子径に応じた時間幅となるパルス状の検知信号を出力する微粒子検知手段と、
前記検知信号を読み取り、単位時間当りの信号の発生量から対応する粒子径のホコリ量を判定する判定手段を備えた微粒子検知装置において、
前記判定手段は、読み取った検知信号のうち、隣り合う大きさとなる小粒子径の検知信号と大粒子径の検知信号の差分に基づいて小粒子径側のホコリ量を判定するように構成した微粒子検知装置。
