New Continuous and Automated Measuring System for Particulate Emissions

The new DT-990, from PCME Ltd world-leading manufacturers of particulate emission monitoring systems, provides continuous and automated measurement for particulate emissions. The instrument design permits up to 32 sensors to be connected to a single control unit which provides automated data recording and PC reporting options for regulatory compliance.

The DT-990 combines precision particle measurement with PCME's unique Electrodynamic measurement principal which is not significantly affected by velocity variations and is unaffected by build-up on the rod surface. It, therefore, provides effective particulate measurement in the most aggressive environments including variable velocity stacks and bagfilters. In addition, PCME's Electrodynamic technique enables the use of fully insulated probes, essential for high humidity gas streams and applications with high conductive dust loadings. This measurement technique also permits measurement at very low concentrations.

The system includes the most advanced automatic zero and span checks available on a probe system to provide full regulatory compatibility. The unique contamination circuit provides the ultimate proof that the sensors measurement integrity is un-compromised.

The advanced user interface includes alarm status, multi-channel bar graphs, text and graph review screens of emissions. Other features include on-board normalisation for T and 02, multi-lingual support and advanced diagnostics for locating broken bags in bagfilters.

Industrial plant operators have long been looking for a rugged particle emission monitoring system which can easily be integrated into plant and PC network systems. The DT-990 provides the security of an independent instrument while satisfying these connectivity requirements.
