Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The device/system may only be set up and used in conjunction with this documentation. Commissioning and
operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes
in this documentation qualified persons are defined as persons who are authorized to commission, ground and
label devices, systems and circuits in accordance with established safety practices and standards.

2.3 Principle of operation
OXYMAT 64
Operating Instructions, 06/2008, A5E00880383-03 13
2.3 Principle of operation
Principle of operation
The measuring cell consists of a ZrO2 membrane arranged as a cylinder (tubular). The
sample gas (with a low O2 content) flows at a constant rate through the inside of the sensor
regulated at 650 °C. The exterior of the sensor is exposed to the ambient air (approx. 21%
O2). The two sides of the ZrO2 membrane are coated with thin platinum films which serve as
electrodes. This produces a stable electrochemical cell. The exterior of this sensor is
exposed to the ambient air (approx. 21% O2). The different O2 concentrations also cause a
different diffusion of the oxygen into the ceramic sensor material. A quantity of oxygen atoms
is ionized equivalent to the oxygen concentration at the electrodes.
A different partial pressure exists due to the differences in concentration on the two sides.
Since ZrO2 is electrically conductive at 650 °C, there is a migration of ions in the direction of
the lower partial pressure.
A gradient in the oxygen ions is produced across the thickness of the ZrO2 membrane which
leads to a potential difference between the two platinum electrodes in accordance with
equation (1).
The inclusion of crystal lattice faults by doping the ZrO2 material with Y2O3 and/or CaO -
originally to prevent the formation of cracks in the ceramic material - increases the diffusion
ability of the O2 ions in the ZrO2 lattice.
Catalytically active ZrO2 sensor (CAZ)
The electrode material is made of platinum (Pt). This type of sensor therefore has a large
cross-sensitivity in the presence of flammable components in the residual gas.
Catalytically inactive ZrO2 sensor (CIZ)
The catalytically inactive sensor has the same basic design as the CAZ auf. However, the
contacts and the electrode surface inside the cylinder are made of a specially developed
material which largely prevents catalytic oxidation of H2, CO and CH4.

Note
Gas inlet conditions
The sample gas must be fed into the analyzer free of dust. The production of condensation
must also be avoided. Therefore, gas modified for the measurement tasks is necessary in
most application cases.

Table 2- 2 Examples of a few non-flammable gases
Measured component / interfering gas Offset caused by interfering gas
8.9 vpm O2 / residual gas Ne -0.3 vpm O2
8.4 vpm O2 / residual gas He -0.26 vpm O2
8.1 vpm O2 / residual gas Ar +0.06 vpm O2
The listed deviations are only exemplary, and can vary by up to ± 0.2 vpm. The actual
deviation must be determined in individual cases, and the error can be eliminated by
appropriate correction of cross-interference (see operating function 83).

2.6 Communication
2.6.1 General information
All gas analyzers of Series 6 such as ULTRAMAT 6, OXYMAT 6/61/64, CALOMAT 6/62,
FIDAMAT 6 as well as ULTRAMAT 23 offer the following communication possibilities:
● ELAN interface
● SIPROM GA (Version 1.9.14 and higher)
● PROFIBUS DP/PA
● Generic communications interface (only ULTRAMAT 6E, OXYMAT/ULTRAMAT 6E,
OXYMAT 61, OXYMAT 6).

2.6.2 ELAN interface
ELAN interface
ELAN is a standard integrated serial interface (RS 485) which allows communication
between several analyzers. You can link a maximum of 12 analyzers with up to four
components. This connection is also possible without a PC.
The functional principle is shown in the following figure:
