SINTROL Dust Monitoring and Dust Detection

Sintrol provides high quality, customer oriented dust measurement solutions, improving its customer’s processes and monitoring their particulate emissions.

Sintrol biedt kwalitatief hoge, proces georiënteerde, oplossingen  voor het detecteren en monitoren van partikels na zakkenfilters en ontstoffings installaties.

Het meetprincipe is gebaseerd op een unieke inductieve elektrificatie techniek. Indien partikels langs de sensor gaan of deze raken ontstaat een signaal dat wordt versterkt en geanalyseerd door een serie van Sintrol’s geavanceerde algoritmes om ruis er uit te filteren en zo een nauwkeurig stofniveau te bepalen.


In each area of the process where there is are single or multiple compartment baghouses, Sintrol Snifter Series monitors are the perfect solution to provide notification to the customer of deterioration or breakage of the filter bags. This provides early detection for the customer that excess particulate matter is in its process and releasing out of the stack. The Sintrol Snifters are largely maintenance free devices that can measure dust levels as low as 0.1 mg/m³.


In many larger or combined outlet ducts, a continuous trend measurement is preferred to get a constant reading on dust levels in the process. The Sintrol S303 monitor is equipped with a 4 – 20mA output and all the features necessary to provide the end user with a continuous output. With high temperature versions (up to 700 °C) available, this is a solution for all areas of the plant with dust measurement needs. The Sintrol S303 monitor allows the customer to identify increasing trends in the dust levels and possibly identify sources of extra pollutants in its process.

For plants that use Electrostatic Precipitators (ESP), our Sintrol E-Spy is the industry’s only probe based monitor allowing the end user to get a continuous trend measurement in 4 – 20mA output after an ESP. The customer can learn about the efficiency of its ESP, optimize the hammering process, and make adjustments to maximize the efficiency of the filter system utilizing the Sintrol E-Spy.


Sintrol’s unique operating principle has allowed it to develop monitors that can accurately provide emissions outputs of dust concentrations in mg/m3. With monitors ranging all the way to a QAL1 certified instrument, Sintrol is able to meet the needs of official stack measurements for end users needing continuous particulate measurements. With ever-increasing global environmental control, Sintrol is able to provide solutions to meet these needs.

For each stack in the plant, Sintrol’s S304 and S305 monitors can be calibrated to provide readings in mg/m³ for actual emissions amounts. Sintrol’s S305 monitor is a TÜV certified instrument, meeting the QAL1 standards, for official emissions measurements in the European Union. These virtually maintenance free monitors are a less expensive and more reliable alternative to the traditional opacity monitors that have been used historically. Also available in ATEX models.


Sintrol’s Dumo family expands our technology to measure dust in ambient air conditions. In welding areas, warehouses, or other environments with high ambient dust concentrations, we can measure relative levels of harmful dust in the work environment. With a continuous 4 – 20mA signal output as well as “Alert” and “Alarm” functions, plant operators can measure the dust concentration levels in the workplace. The same solution has also been used in coal storage yards and for urban dust measurement.

Just as we do with our process and emissions monitors, we have brought our state of the art electric induction measurement principle to ambient dust measurements. This combines the accuracy of relative dust concentrations in heavy industrial processes with the needs of ambient dust control in factory rooms and workshops.


A plant may have different units and dust measurement needs requiring the use of a variety of monitors. Any combination of our monitors* can be connected wirelessly within the same network. The DustLog 8 recognizes each type of monitor within the network and provides access to the parameter settings for each monitor. All signals and alarms are charted in one location for easy access and management. To break down the example on the previous page, we can find several applications being tied into one system.
