High Accuracy Probe Style Zirconia Oxygen Sensor - GMS-10 RVS Series

Product Specification

GMS-10 RVS Series Zirconia Oxygen Sensor Description
The GMS-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 GMS-10 must 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.
