Sintrol Process Monitoring

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.

S201 Dust Monitor

On/Off Switch for filter leak detection

S201 Dust Monitor – 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.

S203 Trend Monitor

Trend Monitor for filter leak detection

S203 Trend monitor with 4-20mA output for continuous dust measurement

Continuous trend monitor that gives plant operators to see the performance of the filtration systems and ducts over a period of time.  Perfect for installation after any filtration system or in common line channels leading into the emissions points of a plant.

State of the art Inductive Electrification principle minimizes the need for maintenance on the  dust monitor and provides an accurate trend for end users.  4-20mA output combined with an easy to use auto-setup feature that takes less than 30 minutes from installation makes the device both convenient and reliable.

S301 Dust Monitor

On/Off Switch for filter leak detection

S301 Dust Monitor – On/Off Switch for filter leak detection
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 deterioration 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 Dust monitor

Trend monitor with 4-20mA output

S303 Dust monitor – Trend monitor with 4-20mA output for continuous dust measurement
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 performance 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 Dust monitor

Emissions monitor

S304 Dust monitor – Emissions monitor that can be calibrated to give mg/m3 output
Combining the S303’s features with the added feature 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 concentration in the process enabling constant monitoring of the dust levels.


Continous dust monitor for post-ESP applications

E-Spy – Continous dust monitor for post-ESP applications
E-Spy is a revolutionary process monitor that helps optimize the performance of an ESP using state-ofthe art probe based technology. Recently developed by our engineers and valuated by research institutes here in Finland, our monitors continuously track the particulate measurements downstream from the ESP enabling plants to not only adhere to the strictest emission regulations, but also reduce overall energy costs. With hundreds of installations worldwide, this has become our fastest growing process control device since it both outperforms and is much more cost effective than the alternative optical monitors. Hundreds of E-Spy have now been installed, and customers are proving to be very satisfied. An increasing number of dust monitors are now being replaced by the Sintrol E-Spy because it is inexpensive, easy to install and commission, requires hardly any maintenance and gives a reliable measurement signal The ESP operator can adjust the parameters to minimize the ESP maintenance requirements, operating costs and the expenses from dust emissions, while meeting all regulatory requirements.
