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 necessary 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 escape 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,
particularly the VDE and DVGW standards that apply in
Germany.
The measurement accuracy and effective function of the
measurement device will need to be checked at intervals
whose frequency will depend on the applicaton
concerned. Such a check must be effected in the course of
a calibration and examination check on the equipment
being first put into operation.
