1. Operational principles
The purpose of ECONOX CarboProbe oxygen sensors is to measure and regulate
atmospheres. ECONOX uses two different types of electrolyte made of ZrO
(zirconium
2
oxide) for its oxygen sensors:
1. A ball made of ZrO
, an ECONOX-patented system, which may only be obtained from
2
ECONOX. The ball is used in the CarboProbe ZI pro sensor.
2. A C-700 ZrO
electrolyte.
2
This is used in the CarboProbe ZS, HT, CP and LTsensors.
An oxygen probe works by comparing the oxygen level in the kiln with the oxygen level
inside the alumina tube. This is why the air inside the tube must always be renewed. If the
temperature of the zirconia tip is over about 700 °C, it produces an electrical voltage. The
less oxygen in the kiln, the bigger the electrical voltage, so the voltage can be used as a
guide to the oxygen level.
There is no safety hazard - the maximum a probe can produce is less than a
battery!
