KGZ10-5PIN

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. FEATURES High-accuracy measurement Low power consumption No reference gas required Linear output signal No need for temperature stabilization Function testing and calibration in ambient air Long life 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.
