DUMO

Continuous dust monitor for trend monitoring in ambient air environments.

With increasing demands for workplace health the ability to measure changes in ambient air dust concentration becomes more important by the day. All areas where dust might cause harm to employees or sensitive devices can now be monitored and dust extraction systems operated accordingly.

Technical Description – DUMO

Inductive Electrification

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.

Classic triboelectric technology is based on the DC signal, which is caused by particles making contact with the sensor to transfer charges. Compared to DC based measurements, the Inductive Electrification technology is more sensitive and minimizes the influence of sensor contamination, temperature drift and velocity changes. By using the Inductive Electrification technology, it is possible to reach dust concentration measurement thresholds as low as 0.01 mg/m3.

DUMO brings Sintrol’s unique Inductive Electrification Technology made famous by the Snifter and S300 series to ambient dust monitoring. With the 4…20 mA isolated output, two user adjustable independent alarm relays and full compatibility with Sintrol Network and DustTool with USB and RS485 communication ensures ease of use and easy connectivity.

DUMO has been updated to utilize Sintrol’s newest and most sensitive measurement technology. New mechanical design makes the device even more robust and tolerant to difficult industrial environments.

EX models (IECEx and ATEX) available. Wireless RF communication available.
