Abstract
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.
