[0014] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of an oxygen concentration measuring device according to an embodiment of the present invention.

[0016] Figure 2 This is a schematic diagram of the structure of an oxygen concentration measuring device installed on a reactor according to an embodiment of the present invention. Detailed Implementation

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0018] First, combine Figure 1 This invention describes an oxygen concentration measuring device according to an embodiment of the present invention, which is used to measure the concentration of oxygen and has a wide range of applications.

[0019] like Figure 1 As shown, an oxygen concentration measuring device according to an embodiment of the present invention has a device body 1, a zirconia pool coating, a zirconia pool section 3, and a connecting seat 4.

[0020] Specifically, such as Figure 1 As shown, the main body 1 of the device is a tubular structure with one end open; a zirconia pool coating is applied to the inner and outer surfaces of the main body 1; a zirconia pool layer 3 is set on the surface of the main body 1 to divide the zirconia pool coating applied to the inner and outer surfaces of the main body 1 into an inner zirconia pool coating 21 and an outer zirconia pool coating 22; and a connecting seat 4 is connected to the main body 1.

[0021] Furthermore, such as Figure 1 As shown, an oxygen concentration measuring device according to an embodiment of the present invention further includes: an outer lead 51 and an inner lead 52. The outer lead 51 is connected to the outer coating 22 of the zirconia bath; the inner lead 52 is connected to the inner coating 21 of the zirconia bath. The outer lead 51 and the inner lead 52 are used for external electrical connections.

[0022] Furthermore, such as Figure 1 As shown, the inner lead 52 and the outer lead 51 are respectively connected to the inner coating 21 of the zirconium oxide pool and the outer coating of the zirconium oxide pool located on both sides of the zirconium oxide pool fault 3, thereby facilitating the connection of the inner and outer leads 51.

[0023] Furthermore, such as Figure 1 As shown, the outer end of the connector 4 is provided with a wrench step 41. The connector 4 can be used to fix the oxygen concentration measuring device to the external equipment by means of threaded connection. The wrench step 41 facilitates loosening and disassembly.

[0024] like Figure 2 As shown, the oxygen concentration measuring device is fixed to the external reactor via the connector 4, allowing the outer coating 22 of the zirconia pool to contact the process gas inside the reactor, and the inner coating 21 of the zirconia pool to contact the external air, thereby measuring the oxygen concentration based on the signals output by the outer lead 51 and the inner lead 52.

[0025] Working principle: When in use, install and connect the oxygen concentration measuring device, then connect the outer lead 51 and the inner lead 52 to the circuit. When starting work, it is heated to above 600℃. The process gas being measured will come into contact with the outer coating 22 of the zirconia cell, and the inner coating 21 of the zirconia cell will come into contact with the outside air. At this time, charge movement will be generated on the inner coating 21 of the zirconia cell. The inner signal is led out through the inner lead 52, and the outer signal is led out through the outer lead 51. The mV voltage signal generated between the inner and outer sides is processed by the electrical part of the instrument, thereby realizing the measurement of the oxygen concentration of the process gas.

[0026] Above, refer to Figures 1-2 An oxygen concentration measuring device according to an embodiment of the present invention is described, which adopts a zirconia bath coating for full coverage, thereby reducing detection time, expanding the measurement range, and increasing the accuracy of the values.

[0027] It should be noted that, in this specification, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above content. Therefore, the scope of protection of the present invention should be defined by the appended claims.
