Series Description

<P>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 pump. 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 customers own electronics, or be purchased as a separate box of electronics from Honeywell.
