UK SST High-Temperature Zirconia Oxygen Sensor - O2S-FR-T2

I. Description of High-Temperature Zirconia Oxygen Sensor O2S-FR-T2:

O2S-FR-T2 is a high-temperature zirconia oxygen sensor with a range of 0.1~100%, capable of operating in environments up to 400°C, making it ideal for applications such as boiler combustion control, bacterial culture, composting, and fermentation.

Rod TypeZirconia Oxygen Sensor(Oxygen Probe) O2S-T2/O2S-FR-T2 uses two zirconia discs with a sealed space between them. One disc functions as a reversible oxygen pump, alternately filling and evacuating this small space with sample gas. The other disc measures the oxygen partial pressure ratio, generating a corresponding sensing voltage. The temperature of 700 °C required for the zirconia disc to operate as an oxygen pump is generated by a heating element. The time taken for the oxygen pump to reach the rated minimum and maximum pressures within the small space corresponds to the oxygen partial pressure in the environment.

II. Typical Applications of High-Temperature Zirconia Oxygen Sensor O2S-FR-T2:

Typical applications include control of heating boilers; control of industrial production processes; control of aircraft onboard oxygen generation systems in the aviation industry; automotive exhaust diagnostics; plant instrumentation; medical oxygen supply equipment; industrial flue gas; oxygen content detection; burner oxygen content detection; oxygen concentrators; submarine oxygen compartments; oxygen bars; ship compartments; oxygen measurement in controlled atmosphere storage; detection of protective gases in food packaging; detection of residual oxygen in fermentation industry; protective gases in production processes (welding, heat treatment); laboratory equipment; oxygen testing in biotechnology and medical systems; any application requiring accurate measurement of oxygen concentration.
Users can supply oxygen; for detecting oxygen in ambient air, users can develop their own control and amplification circuits, or use the original imported matching controller.O2I-Flex。

V. Matching Circuit Board for High-Temperature Zirconia Oxygen Sensor O2S-FR-T2:

UK SST Zirconia Oxygen Sensor Transmitter Board - O2I-Flex-092

The O2I-Flex-092 interface board provides necessary power to electronic components, controls the SST dynamic oxygen sensor, and allows user to set range 0-25% and 0-100%. The entire measurement range is linear. Factory default is 0-25%. When configured for 0-100% range, customers can customize the analog output range to suit the actual application. Output can be configured as: 4-20mA and 0-10VDC or RS232 interface

UK SST Oxygen Transmitter Sensor - OXY-LC-485

The circuit can power and control the SST series dynamic oxygen sensors. The SST seriesoxygen transmitterdoes not directly measure oxygen concentration, but measures the oxygen partial pressure in the gas. To directly output oxygen concentration,oxygen transmitterOXY-LC-485must be calibrated in air or in a gas with a known specific reference concentration. Applications: combustion control including oil, gas, and biomass boilers; composting; laboratory and building air quality monitoring; including personal safety in enclosed spaces, etc.
