[0026] The "range" disclosed in the present application is defined in the form of a lower limit and an upper limit, and a given range is defined by selecting a lower limit and an upper limit, and the selected lower limit and upper limit define the boundary of a specific range. The range defined in this way includes the endpoint values, and can be arbitrarily combined, that is, any lower limit can be combined with any upper limit to form a range. For example, if the range of 60-120 and 80-110 is listed for a specific parameter, it is understood that the range of 60-110 and 80-120 is also expected. In addition, if the minimum range values ​​1 and 2 are listed, and if the maximum range values ​​3, 4 and 5 are listed, the following ranges can all be expected: 1-3, 1-4, 1-5, 2-3, 2-4 and 2-5. In the present application, unless otherwise specified, the numerical range "ab" represents the abbreviation of any real number combination between a and b, wherein a and b are real numbers. For example, the numerical range "0-5" represents that all real numbers between "0-5" have been fully listed herein, and "0-5" is just the abbreviation of these numerical combinations. In addition, when a parameter is expressed as an integer ≥ 2, it is equivalent to disclosing that the parameter is, for example, an integer of 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, etc.

As used in the specification and the appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one, two or more. The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0030] References to "one embodiment", "some embodiments", "an example" or "some examples" described in this specification mean that a particular feature, structure or characteristic described in conjunction with the example is included in one or more examples of the present application. Thus, the phrases "in one embodiment", "in some other examples", "in some other examples", etc. appearing at different places in this specification do not necessarily all refer to the same example, but mean "one or more but not all examples", unless otherwise specifically emphasized. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0031] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different description objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0032] The present application embodiments will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale. In addition, some well-known parts may not be shown in the drawings.

[0033] In order to ensure the measurement accuracy and reliability of temperature and pressure sensors and meet the specific needs of users, each temperature and pressure sensor must undergo standard temperature and pressure stimulation and calibrate the output structure before leaving the factory and being put into use on the market. However, the calibration accuracy of current temperature and pressure sensor calibrators is not very accurate, which often causes large errors in temperature sensors after they are put into use. Therefore, how to improve the calibration accuracy of the calibrator to improve the measurement accuracy of the temperature and pressure sensor is a technical problem that needs to be solved urgently.

[0034] In view of the above problems, the present application provides a calibrator, which has high cavity air tightness and can be closer to the actual pressure detected by the temperature and pressure sensor. This can improve the calibration accuracy and yield of the calibrator, while also improving the calibration capacity.

[0035] The following will describe in detail the calibrator described in the embodiments of the present application in conjunction with the accompanying drawings.

[0036] Figure 1 Schematic diagram of the structure of a calibration instrument according to an embodiment of the present application. Figure 1As shown, the calibrator 100 includes a first part 10 and a second part 20 sequentially arranged along a first direction X; and a receiving cavity 30 , the receiving cavity 30 is used to receive a temperature and pressure sensor, and the temperature and pressure sensor is connected to the second part 20 .

[0037] For example, the first direction X is as follows: Figure 1 As shown, the first direction X may also be referred to as a thickness direction or a height direction of the calibrator 100 .

[0038] Along the first direction X, the first part 10 and the second part 20 are arranged in sequence, that is, it can be said that the first part 10 is arranged above the second part 20 , and it can also be said that the second part 20 is arranged below the first part 10 .

[0039] The accommodating chamber 30 is used to accommodate the temperature and pressure sensor, that is, when the temperature and pressure sensor needs to be calibrated, the calibrator 100 needs to place the temperature and pressure sensor therein to achieve the function of comparing and calibrating the temperature and pressure measured by the temperature and pressure sensor.

[0040] It should be noted that the first part 10 and the second part 20 are arranged in sequence from top to bottom in the first direction X. However, the present application does not limit the specific position of the accommodating cavity 30. The position of the accommodating cavity 30 can be as follows: Figure 1 As shown, it is arranged below the second part 20, and can also be arranged at other positions of the calibrator 100, as long as it plays the role of accommodating the temperature and pressure sensor.

[0041] The temperature and pressure sensor is connected to the second part 20, and the connection here can be an electrical connection. After the electrical connection, the calibrator 100 can power on the temperature and pressure sensor, and can also transmit data or signals.

[0042] Figure 2 FIG. 1 is a schematic diagram of a partial structure of a calibration instrument according to an embodiment of the present application. Figure 2 As shown, the first part 10 includes a first heating component 110, and the second part 20 includes a second heating component 210. Fluids are disposed in the first heating component 110 and the second heating component 210 to provide heat to the first part 10 and the second part 20 respectively.

[0043] That is, the heat of the first part 10 comes from the first heating component 110, that is, the fluid in the first heating component 110 can heat the first part 10. Similarly, the heat of the second part 20 comes from the second heating component 210, that is, the fluid in the second heating component 210 can heat the second part 20.

[0044] In the above scheme, the calibrator 100 includes a first part 10, a second part 20 and a housing cavity 30 for accommodating a temperature and pressure sensor, wherein the second part 20 is connected to the temperature and pressure sensor. Further, the first part 10 and the second part 20 respectively include a first heating component 110 and a second heating component 210, and fluids are provided in the first heating component 110 and the second heating component 210 to provide heat to the first part 10 and the second part 20 respectively. By providing heat to the first part 10 and the second part 20 by heating the fluid, the calibrator 100 can have very good airtightness, so that when calibrating the temperature and pressure sensor, the calibration accuracy and yield can be greatly improved, and the calibrator 100 has relatively simple components, which helps to reduce the difficulty and duration of maintenance, and can also improve the calibration capacity.

[0045] Figure 3 Schematic diagram of the structure of the first heating component of an embodiment of the present application. In some embodiments, the first heating component 110 includes a first heating plate 1101 and a second heating plate 1102 arranged in parallel along a second direction Y, and a third heating plate 1103 and a fourth heating plate 1104 arranged in parallel along a first direction X, and the second direction Y is perpendicular to the first direction X; the first heating plate 1101, the second heating plate 1102, the third heating plate 1103 and the fourth heating plate 1104 are connected to each other to form a first heating chamber 1105, and the first heating chamber 1105 contains a fluid to provide heat to the first part 10.

[0046] For example, the second direction Y is as follows: Figure 3 or Figure 4 As shown, the second direction Y may also be referred to as the length direction of the calibrator 100 .

[0047] That is, in the first heating component 110, the first heating plate 1101 and the second heating plate 1102 are parallel to each other in the second direction Y, and the third heating plate 1103 and the fourth heating plate 1104 are parallel to each other in the first direction X. The first heating plate 1101, the second heating plate 1102, the third heating plate 1103 and the fourth heating plate 1104 are connected to each other and enclose a first heating chamber 1105, and a fluid is disposed in the first heating chamber 1105 to provide heat to the first part 10.

[0048] In the above solution, a plurality of heating plates are connected and enclosed to form a first heating chamber 1105 that can accommodate a fluid, thereby enhancing the air tightness of the calibrator 100 .

[0049] It should be noted here that the present application does not impose any limitation on how to connect multiple heating plates. For example, the heating plates can be connected by welding, bonding, etc.

[0050] It should be noted that a liquid inlet and a liquid outlet may be provided on the first heating component 110 to replace the fluid in the first heating chamber 1105. The present application does not particularly limit the specific positions of the liquid inlet and the liquid outlet. For example, both may be provided on the third heating plate 1103, or the liquid inlet may be provided on the third heating plate 1103, and the liquid outlet may be provided on the second heating plate 1102.

[0052] That is, in the second heating component 210, the fifth heating plate 1201 and the sixth heating plate 1202 are parallel to each other in the second direction Y, and the seventh heating plate 1203 and the eighth heating plate 1204 are parallel to each other in the first direction X. The fifth heating plate 1201, the sixth heating plate 1202, the seventh heating plate 1203 and the eighth heating plate 1204 are connected to each other and enclose and define a second heating chamber 1205, and a fluid is disposed in the second heating chamber 1205 to provide heat to the second portion 20.

[0053] In the above solution, a plurality of heating plates are connected and enclosed to form a second heating chamber 1205 that can accommodate a fluid, thereby enhancing the air tightness of the calibrator 100 .

[0054] It should be noted here that, in the related structure of the first heating component 110, the first heating plate 1101 and the second heating plate 1102 can be called heating plates in the up-down direction, the third heating plate 1103 and the fourth heating plate 1104 can be called heating plates in the left-right direction, and a heating plate in the front-to-back direction is also required to enclose the first heating cavity 1105.

In short, all the heating plates can be assembled to form a sealed cavity with a certain volume. The same is true for the second heating component 210.
