Stack Dust Monitoring

Tribo electric based dust monitor

Principle of Operation

Sintrol dust monitors are based on a unique Inductive Electrification technology. The measurement is based on particles interacting with an isolated probe mounted into the duct or stack. When moving particles pass nearby or hit the probe a signal is induced. This signal is then processed through a series of Sintrol’s advanced algorithms to filter out the noise and provide the most accurate dust measurement output.


S301

Equipped with two independent alarm relays that can be used for early warning and failure, or connected to alarm-devices, S301 is used to detect filter deteriora- tion and blockage or breakage. The alarms can be used for process control (as an ON-OFF system) in flow – no flow situations in bulk solids handling and pneumatic transport applications. Very fast response time, a typical characteristic of these monitors, enables early detection and prevention of expensive product loss to the environment.

S303

With a 4–20 mA analog signal output used for trend monitoring, S303 is installed downstream from a filter, cyclone, dryer or similar devices to monitor filter per- formance as well as particulate emissions. It has two alarm relays that will engage when particulate levels in the gas stream exceed a preset level. It can also be used for process control in certain applications. S301 and S303 are designed for use in any process fitted with bag, ceramic, cartridge filters or cyclones where indicative (qualitative) monitoring is required.


S304

Combining the S303's features with the added fea- ture of allowing calibration to give readings in mg/m3 format, it can give plant operators the ability to see absolute value measurements of dust concentrations. Installed in emissions stacks or in common ducts of a stack, the S304 can give a continuous dust concentra- tion in the process enabling constant monitoring of the dust levels.


S305

Equipped with a Self Zero and Self Span check, the S305 meets all QAL1 requirements for official emis- sions regulations, as proven by its TÜV certification. Used for emissions monitoring in official stack meas- urements for reporting to authorities as well as provid- ing a mg/m3 reading to plant operators. Gives plants a continuous measurement of particulate emissions to ensure it remains within its imposed regulatory limits.
