Continous dust monitor for post-ESP applications

Continous dust monitor for post-ESP applications

As the only probe based dust monitor proven to be a reliable trend monitor after electrostatic precipitators (ESP), the Sintrol ESPY is one of its kind.  With the ability to neutralize the electrostatic field in the outlet duct of an ESP, the ESPY is able to give a trend of relative dust concentrations to help plant operators optimize the use of the ESPs.

ATEX Models

  • Certified for ATEX Zone 20, 21 or 22
  • Approved to Category II 1/2 for Gas and Dust
  • IP65 Enclosure, Custom Designed ● Certification Type: II 1/2 GD EEx ia IIC, T6, IP65, 85°C
  • Utilizing SINTROL’s Advanced Inductive Electrification Technology

The ATEX directive covers health and safety of workers potentially at risk from exposure to explosive environments. This directive classifies areas into Zone 0, 1, 2 for gas and 20, 21 or 22 for dust and guides plant operators to install the appropriate ATEX certified systems. Products are required to be categorized by the level of protection that they offer against the risk of them becoming a potential source of ignition in an explosive atmosphere. The equipment conformity categories are 1, 2 & 3.
