| Abstract: | Powder thickness testing instrument (Model: BX) is a sort of special instrument to test the powder thickness in air. It is used to monitor powder concentration in mine, oil, chemical plant, labor safety, labor sanitation and entironment protecting department. It plays an important role in the life and product production. The optics testing principle, the selecting rule of photoelectricity testing parts, the design of magnifying circuit and the dealing method of electric signal are introduced in this paper. |
