| Abstract: | Application of Hall element in Tapered Element Oscillating Microbalance (TEOM) particulate monitor is introduced. The control circuit of the oscillating tube was designed, which detects the oscillation frequency and maintains an equal amplitude oscillation. The continuous and precise detection of the oscillating tube natural frequency was realized. The experiment data were compared with the officially published data. The comparison results show that the instrument features reasonable design and meets the requirement of on-line air quality monitoring. |
