As shown in fig. 2 to 6, the mounting structure of the sensor provided in the embodiment of the present application includes: a sensor 8 for the passage of a fluid through the conduit 1, and a fixed assembly; wherein the probe end of the sensor 8 is positioned in the pipeline 1; the fixed component is fixedly connected with the sensor 8 and the pipeline 1 at least two positions in the axial direction of the sensor 8; at least one position in the axial direction of the sensor 8, the fixing assembly sealingly connects the sensor 8 and the pipe 1.
In the mounting structure of the sensor provided in the above embodiment, the fixing component is sealed and connected with the sensor 8 and the pipe 1 at least one position in the axial direction of the sensor 8, so as to meet the sealing requirement of the pipe 1; compared with the prior art, the fixing assembly is fixedly connected with the sensor 8 and the pipeline 1 at least two positions in the axial direction of the sensor 8, the fixing positions of the sensor 8 and the pipeline 1 are increased in the axial direction of the sensor 8, the stability of the sensor 8 is improved, and micro-vibration of the sensor 8 caused by fluid is reduced, so that the influence of the fluid on the measuring precision of the sensor 8 is reduced, and the influence of the fluid on the service life of the sensor 8 is also reduced. Based on this, the above-mentioned mounting structure of sensor has improved the measurement accuracy of sensor 8, has prolonged the life of sensor 8.
In actual cases, the specific number of positions where the sensor 8 and the pipe 1 are fixedly connected, and the specific number of positions where the sensor 8 and the pipe 1 are sealingly connected are selected according to actual cases, and this embodiment is not limited thereto.
For simplicity of construction, the number of locations at which the sensor 8 is fixedly connected to the pipe 1 may be chosen to be two, and the number of locations at which the sensor 8 is sealingly connected to the pipe 1 may be one or two.
In some embodiments, at least one location of the sealing connection between the pipe 1 and the sensor 8, and at least one location of the fixed connection between the pipe 1 and the sensor 8 may be selected to be the same location for simplicity of construction.
