These are high-accuracy oxygen sensors suitable for many applications. Originally
developed for boiler applications, the product range has been extended to offer
versions suitable for oxygen monitoring on board commercial and military aircraft,
exhaust gas testing for automotive and medical test equipment.
The sensors employ two ZrO2 discs with a small hermetically sealed chamber in
between. One of the discs functions as a reversible oxygen pump, which is used
to successively fill and empty the chamber. The second disc measures the ratio of
the partial pressure difference and generates a corresponding sense voltage. A
heat element produces the 700 ? C required for the ZrO2 to operate as an O2
The time taken for the pump to achieve specific minimum and maximum pressures
within this chamber is a measure of the partial oxygen pressure of the environment.
The sensors have to be operated by an electronic measuring circuit that controls
sensor operation and signal processing. This circuit can either be incorporated into
the customer? s own electronics, or be purchased as a separate box of
electronics from Honeywell.
