Electrodynamic Dust Monitor View 370 Plus/View 370/Leak Alert 73/75

 

      ►Features

 

Compared with general friction charge methods and the conventional optical detection method, this dust monitor has a high resolution and stability without being easily affected by adhesion of dust to the probe.

  • It is rarely affected by adhesion and contamination on the probe.
  • Extremely high sensitivity of 0.01 to 1000 mg/m3.
  • High-humidity gases can be measured by special air purge. (VIEW370/VIEW370 PLUS)
  • Support for 16-channel sensor (VIEW370 PLUS)
  • It can be connected with our different models using a common path. (VIEW370 PLUS)

      ►Operating Principles  
The charge transfer of fine particles such as dust flowing across a pipe or airflue is applied to static induction and detected by the noncontact sensor. This signal is measured and converted into an alternating-current response. The friction current produced when particles directly hit the probe is cut and this realizes stable output through the special circuit. ELECTRODYNAMIC DUST MONITOR operating principles
