Description

Technical Field

[0001] The present application relates to the field of detection equipment, and in particular to an oxygen sensor chip height detection device. Background Art

[0002] An oxygen sensor chip is a miniature sensor chip used to detect oxygen concentration. It is typically made of a material that can sense oxygen concentration, such as zirconium oxide or titanium oxide. When the oxygen concentration changes, this material generates an electrical signal, which is converted and processed by the chip's internal circuitry, ultimately outputting an electrical signal related to the oxygen concentration. Oxygen sensor chips are widely used in automotive exhaust monitoring, industrial gas analysis, environmental monitoring, and other fields to improve production efficiency, ensure environmental safety, and promote energy conservation and emission reduction.

[0003] Oxygen sensor chips need to be highly inspected during the production process to ensure that the size of the oxygen sensor chip meets the requirements. Oxygen sensor chips with smaller sizes are more inconvenient to inspect. Utility Model Content
