Process Dust Analyzers

Cemtrex Process Dust Analyzers 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 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.


Process Monitoring


Filter Leak Detection
In each area of the process where there are single or multiple compartment baghouses, Snifter Series monitors are the perfect solution to provide notification to the operator of deterioration or breakage of the filter bags. This provides early detection when excess particulate matter is in the process and releasing out of the stack. The Snifters are largely maintenance free devices that can measure dust levels as low as 0.01 mg/m3. ATEX versions are also available for zone 22.


Trend Monitoring
In many larger or combined outlet ducts, a continuous trend measurement signal is preferred to get a constant reading on dust level changes in the process.

The S303 monitor is equipped with a 4–20 mA output signal 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 S303 monitor allows the operator 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 E-Spy is the industry’s only probe based monitor allowing the end user to get a continuous trend measurement in 4–20 mA output after an ESP.

The customer can learn about the eff ectiveness of its ESP, optimize the hammering process, and make adjustments to maximize the efficiency of the filter system utilizing the E-Spy. Also available in ATEX models for zones 20, 21 and 22.


Emissions Monitoring
For each stack in the plant, the S304 and S305 monitors can be calibrated to provide readings in mg/m3 for actual emissions amounts. The S305 monitor is a TÜV certified instrument, meeting the QAL1 requirements 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 for zones 20, 21 and 22.


Ambient Air Monitoring
In welding areas, warehouses, or other environments with high ambient dust concentrations, the Dumo monitors levels of harmful dust in the work environment. With a continuous 4–20 mA signal output as well as “Alert” and “Alarm” functions, the dust concentration levels in the workplace can be measured. The same solution has also been used in coal storage yards and for urban dust measurement.


Snifter A1+, Broken Bag Detection Dust Analyzer

Snifter A1+ is used to detect filter bag breakages quickly and cost-effectively. It is a compact device consisting of an enclosure, housing state of the art electronics and a probe. The Snifter A1+ has the necessary sensitivity to meet the low levels of dust concentrations typical of modern fabric filters. It is able to respond quickly to meet the requirements of bag filters, minimizing maintenance time and downtime in plants.


S300 Series, Dust Analyzer for Trend & Emissions Monitoring

S300 Series can have several different applications in today's industrial fields such as cement and power. It can be utilized as a dust guard, trend monitor, emissions monitor, or a stack monitor. Split Architecture Remote Models are also available for instances where the sensor has to be installed with the control unit up to 200 meters away.


Dumo, Ambient Dust Analyzer

The Dumo monitors Total Suspended Particles (TSP) in ambient air based on the signal generated from moving particles. Test measurements in the laboratory and in the field prove that the Dumo is capable of monitoring low dust concentrations and particle sizes as small as 0.3 micrometers. Dumo is easy to install and commission and virtually maintenance free.
