Insitec D

Summary

Insitec D provides robust, reliable on-line particle sizing for dry powder applications and is ideal for process optimization and control applications.

Compliance with the new ATEX regulations (99/92/EC and 94/9/EC) – mandatory for existing workplaces from July 2006 – results for the first time in the zoning of areas that are potentially explosive due to the presence of dust. The Insitec D has been approved for Zone 22 use (Category 3 approval).

General

Designed for hazardous environments, the Insitec D is certified for use in dust environments classified as ATEX Zone 22. The hardware comprises of IP66 rated optical sensor which includes solid state laser diode, multi-element detector, high-speed parallel processor and process sample flow cell.

Certification :
