    2.1 Information about this manual  This manual describes the operation, features and maintenance of the Si-CA 320 Flue gas analyzer.  Read this instruction and maintenance manual before using the instrument. The operator must have a full understanding of the manual and follow the instructions within.

  • Page 7: Safety

    3.3 Non-authorised use of the product Use of the Si-CA 320 in areas of application other than those mentioned in the chapter 3.2"Correct use of the product" is the sole responsibility of the operator and the manufacturer assumes no responsibility for any loss, damage or costs that may result therefrom. It is recommended to read and pay attention to the instructions in this user and instruction manual.

  • Page 8: Working Principle

    4 WORKING PRINCIPLE 4.1 Working principle The Si-CA 320 is a portable analyser for combustion and emissions analysis. The device is equipped with: • A pneumatic circuit that can contain up to 6 sensors • An intuitive user interface allowing the device to be used without the operating instructions •...

  • Page 9: Product Description

    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.
  • Page 10 If there is an automatic autozero solenoid valve, the unit automatically performs a purging cycle and stops when the sensor returns to a value close to zero. Sauermann certifies the accuracy of the measurements only under cover of a calibration certificate issued by its laboratories or by another approved laboratory.

SOME IMPORTANT WARNINGS TO CONSIDER DURING THE COMBUSTION ANALYSIS ARE LISTED BELOW: FOR A CORRECT ANALYSIS NO AIR MUST FLOW INTO THE PIPE FROM OUTSIDE DUE TO A BAD TIGHTENING OF THE CONE OR A LEAK IN THE PIPELINE.

  • Page 91: Simultaneous Measurement Of Pressure, O , Pollutants

    The correct point of introduction of the probe into the chimney is the point corresponding to a distance from the boiler of twice the diameter of the flue gas nozzle or, if this is not possible, in accordance with the instructions of the boiler manufacturer. To position the probe, it is necessary to make a hole of about 13/16 mm (if there isn’t one already) in the flue gas duct and screw in the positioning cone supplied with the probe so as to provide a good support for when it is introduced, thus avoiding taking air from the outside.
