1.2 DCEM2000 Basic Principles
– The DCEM2000 is a dual-pass transmissometer configured for the measurement of opacity and dust concentration within the flue gas. Its unique optical arrangement provides continuous measurements of transmissivity of visible light across the stack in opposite directions, providing not only an accurate average of the dust loading in the stack, but a dynamic assessment of any mis-alignment errors that may occur due to stack movement.
– The monitor incorporates integral automatic procedures for determining zero and span and interfaces directly with the SmartCEM local data bus, so that all diagnostic and measurement data may be accessed by the Station Control Unit (SCU) […]
