Operating Instructions, 01/2019, A5E00222135-04
● External pressure sensor can be connected for correction of process gas pressure
fluctuations
● Easy device replacement since electrical connections of the device can be easily
disconnected
● No clogging in the sample gas capillary tube thanks to the use of a quartz capillary tube
● Wear-free, corrosion-proof filter
● Required combustion gas: hydrogen (H
2
)
● Communication via RS485 in the basic unit
Functions
The devices have the following functions:
● Menu-driven operation for parameterization, test functions, calibration
● Four measuring ranges can be user-configured, including with suppressed zero point, all
measuring ranges are linear
● Automatic or manual measuring range switchover can be selected; remote switchover
also possible
● Measuring point switchover for up to 6 measuring points
● Three operation levels with their own authorization code to prevent accidental and
unauthorized operator interventions.
● Automatic measuring range calibration can be configured
● Measured values can be saved while calibrating
● Flushing function in the event of analyzer or power supply failure (avoids build-up of toxic
and corrosive substances in the device)
● PROFIBUS (DP/PA) interface (optional)
● AUTOCAL (optional)
3.1.3 Certified operation for emission monitoring according to EN 15267-3
Some device versions are designed and certified by the TÜV for measurement of oil, coal,
gas and waste fuels in flue gases according to 13th BlmSchV/17th BlmSchV and TA Luft.
Furthermore, these devices meet the requirements of ISO 14965 and QAL 1 according to
EN 14181.
Application according to 13th, 30th and 31st BImSchV and TA Luft
This function pertains only to device version 7MB2421-xDA1x-1AAx–Y27.
For certified operation, a compensation of the influence of interference gas caused by
oxygen is required. For this purpose, the analyzer must be supplied with the current oxygen
concentration value of the sample gas. This is done by an external measuring instrument,
which must also meet the requirements of EN 15267-3 (e.g. ULTRAMAT 23 or OXYMAT 6).
