KGZ-NGL-096-273 Zirconia Oxygen Gas Sensor Flange Flange installation

The oxygen sensor uses two zirconium oxide disks with a sealed space in between. One of the dishes acts as a reversible oxygen pump, filling the sample and emptying the small space in turn. The other plate is used to measure the ratio of the oxygen partial pressure difference to obtain the corresponding induced voltage. The 700 °C temperature required to operate the zirconium oxide disk as an oxygen pump is generated by a heating element. The time it takes for the oxygen pump to reach the rated lower and higher pressures in the small space has a corresponding relationship with the oxygen partial pressure in the environment.
