10.2 Marking
The marking is reproduced on a separate piece of paper
shipped with the instrument.
Serial Number key: The third letter of the serial number
specifies the manufacturing year: A = 2009, B = 2010,
C = 2011, D = 2012, E = 2013, F = 2014, H = 2015, J = 2016,
K = 2017, etc.
Example: Serial Number ARCB-0103: the third letter is C,
which means that the unit was manufactured in 2011.
10.3 Signal transmission to central controller
10.3.1 Analog signal
10.3.2 HART digital communication
10.4 Power supply and relays
10.5 Physical specifications
10.6 Environmental parameters
10.7 Environmental influences
For influences on the measurement performance and
restrictions of a particular sensor see sensor data sheet.
NOTICE
The table shows the response of the sensor to other
gases than the target gas (cross sensitivities). The
listed values are typical and are valid for new sensors.
The table does not claim to be complete. Gas mixtures
can be displayed as the sum of all components.
Gases with a negative cross sensitivity can cancel out
a positive sensor signal. The influence of the O
2
displacement is not taken into account (partial
pressure measurement).
Example:
2 Vol% ethylene in the air - cross sensitivity (table
value) = -1 Vol% O
2
.
O
2
displacement caused by 2 Vol% ethylene (2% of 20
Vol% O
2
) = -0.4 Vol% O
2
Instrument display (20.9 - 1 - 0.4) = 19.5 Vol% O
2
.
CAUTION
The exposure to higher concentrations of unsaturated
hydrocarbons, alcohols or hydrogen over an extended
period of time (dose approx. 100,000 ppm x hours)
could cause the sensor to fail.
NOTICE
Frequency of measurement calculation: 1 x per
second (update of display, analog interface and
relays).
