Siemens QGO20.000D27 - O2 sensor, for combustion optimization, AC230V. 

Siemens QGO20 Oxygen sensor

The QGO20 is an oxygen sensor that is used to acquire the residual oxygen content of flue gases in heat generating plants that burn natural gas or light fuel oil. In connection with the control unit (LMV52 with PLL52), QGO20 monitors and controls the combustion process. For mounting the QGO20, flue gas collectors type AGO20 are available. They can be welded directly into the chimney. The QGO20 in connection with the AGO20 is suited for use on all types of heat generating plant which burn natural gas or light fuel oil with flue gas temperatures up to 300 °C at the test point. When used in connection with burner controls type LMV52 for residual oxygen control, the efficiency of combustion will be improved and oxygen emissions minimized.
