Summary: | The utility model provides an oxygen sensor with a packaging structure. The device comprises a detection chip, a stainless steel shell and a base, the detection chip is arranged in the stainless steelshell; the stainless steel shell and the base are welded and fixed. A binding post connected to an external circuit is arranged on the base; wherein the electrode end of the detection chip is weldedand fixed with the binding post through a welding wire, the periphery of the detection chip in the stainless steel shell is also filled with a thermal insulation material, the top end of the stainlesssteel shell is also provided with a through hole, and a stainless steel metal net is fixedly arranged in the through hole. When the atmospheric oxygen concentration is measured, the chip is low in power and low in energy consumption; a double-heat-preservation structure of the shell and the high-temperature cotton is arranged, so that the influence of the environment on the chip during working issmall, and the response spe |
