Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 2, 3, 4 and 5, the high temperature and high pressure sensor with the hollowed-out ceramic structure includes a sensing end and a ceramic tube 10, wherein the sensing end includes a sensing element 20 and a wire 30. The ceramic tube 10 is provided with a first receiving hole 12 and a second receiving hole 14 which are communicated with each other, the sensing element 20 is arranged in the first receiving hole 12, the end of the wire 30 is arranged in the second receiving hole 14 and is electrically connected with the sensing element 20, and a gap between the ceramic tube 10 and the sensing end is filled with high-temperature ceramic glue 40.
The sensing element 20 and the wire 30 of the sensing end are respectively placed in the first receiving hole 12 and the second receiving hole 14 of the ceramic tube 10, and then the gap between the ceramic tube 10 and the sensing end is filled with the high-temperature ceramic paste 40. The ceramic tube 10 is used as an insulating outer sleeve, and then the high-temperature ceramic glue 40 is used for filling a gap between the ceramic tube 10 and the sensing end, so that under the condition that the size of a product is limited, the pressure resistance of the product is ensured, the temperature resistance of the product is enhanced, the temperature can reach 500 ℃ and higher, and the application of the product is wider and more firm.
In this embodiment, compared with the prior art, a ceramic material with higher temperature resistance is selected, and then the ceramic tube 10 is made, so that the temperature resistance level of the whole product is higher than that of the first floor under the condition of ensuring insulation and pressure resistance. In other embodiments, other temperature-resistant insulating materials can be selected to replace the ceramic material.
In this embodiment, the second receiving hole 14 includes a first wire hole 142 and a second wire hole 144 that are disposed at an interval. Specifically, the first wire hole 142 and the second wire hole 144 isolate different wires of the wire 30, thereby preventing the two from contacting and affecting the product performance.
In this embodiment, the high-temperature and high-pressure sensor with the hollow ceramic structure further includes a housing 50, and the ceramic tube 10 is installed in the housing 50. Further, a gap between the outer shell 50 and the ceramic tube 10 is filled with a high temperature ceramic paste 40. Specifically, the inner diameter of the outer shell 50 is larger than the outer diameter of the ceramic tube 10, so that the gap between the outer shell 50 and the ceramic tube 10 is filled with the high-temperature ceramic paste 40.
When the product is installed, the sensing element 20 and the wire 30 may be electrically connected, then the wire 30 passes through the second receiving hole 14, after the wire 30 passes through to the bottom, the sensing element 20 is just located in the first receiving hole 12, then the gap of the ceramic tube 10 is filled with the high temperature ceramic glue 40, and finally the upper half product is put into the housing 50 of the temperature sensor, and the gap is filled with the high temperature ceramic glue 40 continuously. Because the high-temperature ceramic paste 40 needs to be filled, a larger space can be reserved in the first accommodating hole 12, so that the product is not limited by the external dimension of the temperature sensing element.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
