2 Preface
With the aid of an oxygen sensor , the measurement unit serves to measure the oxygen partial
pressure in gaseous atmospheres. Such sensors work at high temperatures and so it is neces-
sary for measures to be taken to ensure that no flammable gas mixtures contact the sensor or
the unit. In the event of the sensor ceramic suffering breakage the measurement gas could es-
cape or air could enter the measurement gas side of the unit and so suitable measures have to
be taken to avoid such an event leading to environmental pollution or damage being done to
equipment.
In the event of incorrect parameters being set or the occurance of leakage, corrosion,
condensation, etc., damage could be done to the equipment and incorrect measurement
results be indicated and so it is essential that all parts of equipment be regularly
serviced.
The oxygen sensor and its accessories are subjected to
thorough quality control in accordance with DIN ISO
9001 in the course of their manufacture and testing.
They must only be installated and used in compliance
with all applicable local and special regulations, partic-
ularly the VDE and DVGW standards that apply in Ger-
many.
The measurement accuracy and effective function of the
measurement device will need to be checked at intervals
whose frequency will depend on the applicaton con-
cerned. Such a check must be effected in the course of a
calibration and examination check on the equipment be-
ing first put into operation.
