Title:
BRAKE DUST MEASUREMENT DEVICE, BRAKE DUST MEASUREMENT METHOD, AND BRAKE DUST MEASUREMENT PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/130853
Kind Code:
A1
Abstract:
To make it possible to accurately measure an amount of brake dust, or the like, even if a main flow rate has been changed, a brake dust measurement device (100) for measuring brake dust produced by a brake (Z) is made to comprise a main flow path (L2) that a sample gas including the brake dust flows through, a sampling flow path (L3) that is connected to a sampling point (X) set on the main flow path (L2) and collects some of the sample gas, and a flow rate control mechanism for controlling a sampling flow rate that is the flow rate of the sampling flow path (L3) such that the same is proportional to a main flow rate that is the flow rate of the main flow path.
