Introduction
Thank you for selecting the Super Systems Inc. (SSi) SuperOX TM Sensor for your combustion
control application.
SuperOX
TM
represents "state of the art" in oxygen sensor technology. It has been designed for
use in combustion control systems for glass, power, steel reheat, chemical process and
incineration applications.
SuperOX
TM
, with its patented measuring electrode construction, is the product of a team of
design and application engineers, each with over twenty years of atmosphere control
experience. The SSi engineering team has long recognized that the sensor is the most critical
component in a control system and has traditionally been the weakest link. Now, reliability,
repeatability and accuracy are assured with the use of SSi’s SuperOX
TM
high temperature, in situ
sensor in your system.

Characteristics
The typical zirconia oxygen sensor consists of a closed end tube with the sensing portion at the
tip. The tube operates on the principle of yttria-stabilized zirconia. Figure 1 illustrates the
SuperOX TM Sensor design with details omitted for clarity. The tip of the tube is spring loaded into
contact with the outer, negative platinum electrode, which is in contact with the ceramic sheath.
The inner, positive electrode is spring loaded into contact with the inner zirconia surface. A
thermocouple is positioned close to the inner electrode surface and reference air bathes the
sensing surface.
