Triboelectric Dust Monitor & Switch

Description

Dust Monitor continuously measures for 24 h the dust in exhaust gas at the secondary side of a dust collector or the like and outputs the alarm signal at the abnormal condition and monitors the relative variation of dust amount with an analog signal. It detects the triboelectric charge of dust hitting the sensor probe and make outputs relative to the dust amount. Dust Monitor can be easily mounted on the existing facility to facilitate environmental management.

  • Produces the same high performance as optical systems at lower cost.
  • Requires no special training or skill easy to install and to adjust.
  • All components are made in Japan for ensured high quality and excellent customer service.
