General description of the Flue gas analyzer
The Si-CA 320 portable flue gas analyzer has a sleek and ergonomic design and an extremely clear and intuitive keyboard.
Designed to satisfy both Flue gas analysis and pollutant (emission) monitoring and environmental parameter measurements, the Si-CA
320 uses two electrochemical sensors that provide oxygen and carbon monoxide values.
The environmental parameters are measured by external sensors and it is also possible to measure both the chimney draught and the
opacity category. In addition, by using the measurement scale up to 200 mbar, the system pressure and combustion chamber pressure
can be measured, and the pressure switch verified.
Designed for the eleven main fuel types such as natural gas, LPG, diesel and fuel oil, the Si-CA 320 also allows 16 other fuels of known
chemical composition to be added to the memory. Saving and averaging the acquired data, printing the results (on a plain paper roll) and
connecting to the computer for data storage via USB connection, are all features of the Si-CA 320.
The memory can store 1000 complete analyses using the appropriate software and the mini-USB communication cable. There is the
option of downloading the data to a PC.
The instrument also comes with a large (55 x 95mm) bright colour TFT display, including a zoom function and backlighting for excellent
readability.
Another feature that sets it apart from many similar products on the market is that the power supply provided with the product can
perform the dual function of both charging and supplying power to the device, thus allowing the user to perform an analysis even when
the batteries are fully discharged.
Finally, one other important function is the option to perform the reset cycle with the probe introduced into the chimney using a
sophisticated flow deflection system.
With regard to maintenance, it is useful to know that because they are pre-calibrated, the sensors can be replaced directly by the user
without having to send the instrument to a service centre; in any event, however, the instrument must be calibrated at least once a year.
In addition:
•
Operator interface
: so intuitive that it can be used without a need to refer to the instruction manual.
•
Large, bright and colourful TFT display:
great readability thanks to zoom function and efficient backlighting.
•
Only one Li-Ion battery pack:
rechargeable for powering the device, complete with charge indication and ability to access it from the outside.
•
Pneumatic input connectors (gas and pressure/draught) not exceeding the external profile of the instrument:
For better resistance to shocks.
•
Pre-calibrated sensors that can be replaced directly by the user.

General characteristics of the Flue gas analyzer
The Si-CA 320 portable analyser has been carefully designed in accordance with Client-specific standards and requirements.
The analyser contains a single electronic board with all the main circuits for its basic operation, laboratory pre-calibrated measuring
sensors, smoke extraction pump, membrane keyboard and TFT graphic display with LCD backlight. The two parts of the housing are
securely attached to each other with seven screws in the rear part of the analyser.
The pneumatic circuit and the measuring sensors with electronic modules are positioned in the rear part of the housing and are accessible
for quick maintenance or replacement by removing the magnetic cover located in the lower part of the instrument. Located on the lower
side of the analyser are the pneumatic connectors for smoke sampling and pressure/draft measurements, the T1 connector for connection
to the thermocouple plug of the gas probe, and the T2 connector for connection to the thermocouple plug of the combustion air probe.
Located on the right side are the USB port type B for connection to the external power supply or PC, and the mini DIN 8-pin port for the
serial interface or for an external probe (optional).
The user interface consists of the graphic TFT display with backlighting that is always on and the membrane keypad. The on-screen
menu and all operator notifications can be configured in the language of the user.
Using the analyser is simplified thanks to the symbol keys that provide access to the most important functions. Navigating between the
different menu programs is easy and intuitive.
Smoke extraction pump
The pump, inside the analyser, is a diaphragm pump with a direct current motor and powered directly by the instrument in order to obtain the
optimal combustion sample range for analysis; an internal range measurement sensor allows:
-
keep the pump capacity constant
-
check the efficiency of the pump
-
check the level of filter clogging
Simultaneous measurement of pressures, O
2
and pollutants
In order to optimise the combustion parameters of the boiler, the instrument allows the simultaneous measurement of the gas valve inlet and outlet
pressure, O
2
level, pollutant levels and all the calculated parameters that are necessary to obtain an accurate efficiency value.
