Description
Technical Description – S201 DustGuard
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.
A Closer Look
On/Off Switch for filter leak detection
With two independent alarm relays, Sintrol’s S201 allows the end user to identify bag leaks and deterioration of filters. Using our electric induction measurement principle, the dust monitor can be easily set up within 30 minutes of installation and gives plant operators quick notification of breaches in the filtration system. Sintrol dust monitor allows end users to manually adjust alert and alarm level signals to tailor to their end needs. Different probe lengths and coatings give flexibility to meet a variety of applications
- Straightforward filter leak detection on an ALERT and ALARM signal base
- Minimise product loss by finding even the smallest leakages
- Identify broken solenoid valves
- Monitor pulse efficiency and reduce pulse rates
- Reduce consumption of compressed air
- Enable preventive maintenance
- Proactively reduce emergency downtime
