Description

Technical Field

[0001] The invention relates to the field of gas detection, in particular to an ultra-high precision lithium tantalate gas detector. Background Art

[0002] Lithium tantalate has excellent electro-optical, piezoelectric and pyroelectric properties, which make it have potential application value in the field of gas detection. The lithium tantalate gas detector is a gas detection device designed based on lithium tantalate material. It uses the physical and chemical properties of lithium tantalate to detect specific gases or gas concentrations. When gas molecules interact with the lithium tantalate crystals on the surface of the detector, it will cause changes in the charge distribution inside the crystal, thereby generating electrical signals. After amplification and processing, these electrical signals can be converted into measurable outputs to indicate the presence or concentration of gas.

[0003] The following deficiencies exist in the prior art: current lithium tantalate gas detectors are all covered by tube caps, and are sealed with the tube socket using a TO39 packaging method. However, since sensitive components, circuit boards, connectors, etc. are installed inside the tube caps, bumps or drops may occur during the process of taking, carrying, and installing. In severe cases, this may directly cause damage to the internal accessories of the tube caps or degradation of their performance. Summary of the invention
