KGZ-10 Series
Oxygen Sensors
DESCRIPTION
The KGZ-10 is a high-accuracy, zirconia-based oxygen sensor.
The ability of the sensor to operate without any reference gas
makes it ideal for potential applications such as combustion
control or aircraft oxygen generation systems.
The sensor employs 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 [1292 F]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 KGZ-10 has to be operated by an electronic measuring
circuit that controls the sensor operation and signal processing.
This circuit can either be incorporated into the customer s own
electronics, or be purchased as a separate interface board
from Honeywell.
