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.

Sensors can be supplied in various lengths, coated or not, depending on the process conditions.

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.

ATEX versions available. Please contact us for this.

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. S303 is designed for use in any process fitted with bag, ceramic, cartridge filters or cyclones where indicative (qualitative) monitoring is required.


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.
