    • A device for detecting particulates includes: a filter; a filter container; an upstream pipe; a downstream pipe; an upstream detecting unit; and a downstream detecting unit. The upstream detecting unit has a branch flow route for receiving gas from the upstream pipe, a trapping portion, a transmitting portion for transmitting an electromagnetic wave to the trapping portion, and a receiving portion for receiving an electromagnetic wave from the trapping portion. The downstream detecting unit has a branch flow route for receiving gas from the downstream pipe, a trapping portion, a transmitting portion for transmitting an electromagnetic wave to the trapping portion, and a receiving portion for receiving an electromagnetic wave from the trapping portion. The amount of the particulates trapped in the filter is detected based on a difference between detection values of the mass of the particulates trapped in the upstream and downstream trapping portions.
    • 用于检测微粒的装置包括:过滤器; 过滤容器; 上游管道 下游管道 上游检测单元; 和下游检测单元。 上游检测单元具有用于从上游管接收气体的分支流动路径,捕获部分,用于将电磁波发送到捕获部分的发送部分和用于从捕获部分接收电磁波的接收部分。 下游检测单元具有用于从下游管接收气体的分支流动路径,捕获部分,用于将电磁波发送到捕获部分的发送部分和用于从捕获部分接收电磁波的接收部分。 基于捕集在上游捕集部和下游捕获部中的微粒的质量的检测值之差来检测捕集在过滤器中的微粒的量。

    • A device for detecting an accumulation amount of particulates is provided. The device has a filter for trapping particulates from a gas containing the particulates, a container for containing the filter, an upstream pipe provided on the upstream side of the container to lead the gas into the container, a downstream pipe provided on the downstream side of the container to lead the gas after passed through the filter, a transmitting antenna provided within the downstream pipe to transmit an electromagnetic wave having a frequency of 30 GHz or more but not exceeding 10 THz, and a receiving antenna provided within the upstream pipe to receive the electromagnetic wave. An amount of the particulates trapped in the filter is detected based on an intensity of the electromagnetic wave received by the receiving antenna.
