2.2 Main features

• Screen
  Color touch screen, 10.9 cm (4.3’’), 480 x 272 pixels with backlight. It allows to display measured parameters in a more comfortable format for the operator. Thanks to the zoom function, you can view on the screen the measured values in increased or  decreased characters.

• Battery charger
  The instrument is supplied with a 5 V, 2 A power adapter to charge the internal batteries. The current loading is indicated by a battery symbol on the top right of the screen. To ensure a complete charge, the battery charging time is 6.5 hours.
  The voltage of the power supply is 100-240 VAC, 50/60 Hz. The USB cable included with the analyzer connects the power supply to the device.

• Flue gas suction pump
  The pump, inside the gas analyser, is a diaphragm pump with a motor. It is energized in direct current directly by the instrument in a way to get an optimal suction of flue gases.

• Flue gas probe
  Probe in stainless steel with a handle in plastic, with a standard length of 30 cm (12″) and with an adjustable positioning cone to maintain the contact tip inside the duct. The probe is connected to the instrument by 3 m (10′) of dual hose. Other probe  lengths (75 cm, 1 m and 1.5 m) are avalaible as options.

• Interchangeable measurement sensors
  The analyzer uses electrochemical sensors to measure the oxygen and the carbon monoxide (compensated in H2 hydrogen). Measurement sensors (including NO, Low NO,NO2, Low NO2, SO2, Low SO2 , CxHy and H2 S) are interchangeable.
  Regularly recharge the battery to guarantee an optimal operating of the electrochemical sensors. It is absolutely necessary to avoid falling to 0% battery as this would irreversibly damage the cells.

• Temperature sensors
  Flue gas temperature is measured with a thermocouple integrated in the contact tip. The connection to the analyzer is made thanks to a single male type K thermocouple (nickel-nickel chromium) connector for measurements up to 1250 °C (2282 °F).
  The instrument has a NTC thermoresistance sensor for the measurement of internal temperature; this sensor is also used for the measurement of ambient temperature.
  If a temperature control of the combustive air must be performed directly by the supply duct (e.g.room sealed boiler), a TcK temperature probe can used. It is recommended to perform this measurement to make the efficiency calculation of the installation  more precise.

• Pressure sensors
  The standard semiconductor type pressure sensor can measure draft and differential pressure (deltaP) for a range of ±200 mbar (±80 in WC). An optional high accuracy pressure measurement can be added for a range of ±500 Pa.

• Supply input of flue gases and +/- pressure
  There are two hose connections coming from the probe that connect to the bottom of the analyzer. One comes from the water trap assembly and connects to the gas inlet (labelled “G” and colored black) while the other connects to the high pressure inlet  (labelled “P+” and colored orange).

• Fuel types
  The analyzer is supplied with technical data which characterizes the most common fuels. It is also possible to add user defined fuels and their corresponding coefficients if needed.

• Calibration certificate
  The analyzer is calibrated by comparison with standard of metrology laboratories, which are periodically certified closed to laboratories known at the international level. Each analyzer is supplied with its calibration certificate in which, for each measured parameter, are indicated the nominal value, the one measured, the admitted error limits and the found error.
  It is advised to calibrate the instrument at least once a year.

• Conformity and standards
  The analyser complies with 2014/53/EU (RED) and 2015/863 EU (RoHS 3). Document available on request.Moreover, the analyser complies with EN 50379-1 and EN 50379-2, UNI 7129; UNI 11137, UNI 10389, UNI 10845, UL & cUL Certification, BS 7967:2015, BS EN 50543:2011, UNE 60670-10 and ES.02173.ES
  Hereby, Sauermann Industrie SAS declares that the radio equipment type Si-CA 230 is in compliance with Directive 2014/53/EU. The full text of the EU declaration of conformity is available at the following internet address: www.sauermanngroup.com

• Water trap
  The analyzer has an external water trap assembly that hangs directly below the analyzer. The flue gas is cooled and dried in the lower chamber. Accumulated condensate must be manually drained as needed. The upper chamber has a filter cartridge to  remove dust and particulates from the flue gas. The filter should be replaced periodically as needed.
  THE WATER TRAP MUST BE IN VERTICAL POSITION AT ALL TIMES DURING OPERATIONS FOR OPTIMAL PERFORMANCE!
  The water trap must be emptied before storing it in the transport case.

• CO dilution
  The instrument has the CO dilution function to prevent high CO concentrations from over saturating the CO sensor. These high concentrations can damage the analyzer and the CO sensor. This function allows high CO measurements without damaging the  sensor. In dilution function, the measuring range becomes 0-5% (50 000 ppm).

12.5 Perform a Stack Gas Velocity measurement with a Pitot tube
To perform this test, it is necessary to have a Pitot tube Type L or Type S.
Place and connect the L Pitot tube:
The Pitot tube must be introduced perpendicularly, in the middle into the duct and parallel to the flow.
The head (ending with an ellipsoidal nose) must be maintained parallel and facing the flow.
The total pressure (+) caught by the nose, is connected to the P+ at the bottom of the analyzer.
The static pressure (-) caught by the holes of the head, is connected to the P- at the bottom of the analyzer.

Place and connect the S Pitot tube:
The S-type Pitot tube is inserted into the stack and rotated until the differential pressure measurement is greatest for a given location in the stack.
The proper orientation is for the high pres- sure side of the S-type Pitot tube tip to face into the direction of the stack gas flow as shown in the diagram.
The holes must be perfectly aligned with the air or gas flow direction.
The Pitot tube S is more sensitive to alignment errors thas the Pitot tube L. The connecting to the measurement device must be carried out like following:

• The leg in front of the air flow is connected to the P+ sign of the analyzer.
• The leg at the opposite of the air flow is connected to the P– sign of the analyzer

When the connections are made and “Other measurements” screen is displayed :
• Tap “Stack Gas Velocity”.
The analyzer displays the following measurements: Velocity, Volume flow and Mass Flow.

• Tap the K value to modify it if necessary (K value must be between 0.0000 and 99.0000).
  Recommended values are: 0.84 for S-Type Pilot tube and 1.0015 for L-Type Pilot tube.

• For proper calculations of volumetric flow rate and mass flow rate, enter correct stack cross-sectional (see chapter “7.13 Set the stack cross-sectional area” on page 24)

12.6 Perform a measurement of smoke/opacity
It is possible to enter in the analyzer from 1 to 3 smoke/opacity indexes performed thanks to smoke/opacity pump available as option.
The smoke/opacity index consists of the measurement of solid waste of combustion in the flue with a pump and a filter of measurement.
The filter coloration is compared with a table reference composed by 10 greyed areas numbered from 0 to 9.

12.6.1 Perform the measurement
Preliminary operation: to avoid the condensation in the pump, it is necessary to breathe in WITHOUT FILTER fresh air before performing a measurement

• Put the paper filter in the pump.

• Insert tip of pump into the flue/stack.
  The necessary gas volume for a measurement of opacity corresponds to about 10 pump strokes.

• Compare the filter clogging to the reference table to determine the opacity index.

• Make the same operation several times if necessary, replace the filter each time.

Maintenance of the analyzer

13.1 Life-time of the sensors
Gas sensors are electrochemical type: inside them, in the presence of gas to detect, a chemical reaction occurs that causes an emission of electrical current. The electric current strength detected by the instrument is converted into a corresponding gas concentration. The life-time of the sensor is strongly linked to the reagent consumption present in the sensor.
As their consumption increases, features of the sensor are getting worse until their exhaustion, after which it is necessary to replace it.
To ensure the measurement accuracy, sensors have to be calibrated only in Assistance center qualified by Sauermann.

Regularly recharge the battery to guarantee optimal operations of the electrochemical sensors.
Do not leave the instrument an empty battery charge. Make sure the battery is always charged even during a long period of non use.

13.2 Replaced used sensor
Follow this procedure to replace a used sensor:
The analyzer must be turned OFF

• Remove the protective rubber holster.
• Turn the analyzer on its back side.
• Open the analyzer by removing 6 screws with cruciform (Philips) screwdriver. The back shell can then be lifted up.
• Pull used sensor (1) up off the black manifold (3).
• Remove black rubber cap (2) off used sensor and push cap onto new sensor.
• Mount new sensor with rubber cap starting by connecting onto manifold’s pins (5) then make sure to properly align to 10 metal pins (6) into the mating black connector (4). Push sensor down to make sure connections are secure.

Sensors have very precise locations, see the following locations defined for each sensor:

• O2 sensor must be in O2 position
• CO-H2 sensor must be in CO position
• NO or low NO sensor must be in 6 position
• NO2 , SO2 , low NO2 , low SO2 , CxHy and H2 S sensors must be in 3, 4 or 5 position.

When a sensor has been replaced, it is possible to check the proper functioning of this new sensor by going in the “Information” menu of the analyser. It is normal that a sensor that has just been installed gives the following message: “Current Error”, it is necessary to wait designated time to stabilize the polarization of the sensor.
Here are the minimum stabilisation times for each sensor:

• O2 : 1 hour
• CO-H2 : 8 hours
• NO: 12 hours
• Low NO: 12 hours
• NO2 : 8 hours
• Low NO2:
• SO2 : 8 hours
• Low SO2 : 8 hours
• H2 S: 8 hours
• CxHy: 8 hours
