[0029] Example 1

[0030] like Figures 1-2 As shown, this embodiment provides a temperature sensor structure for a Coriolis mass flow meter, including a metal mounting base 1, a temperature sensing element 2, and a wire 3. The temperature sensing element 2 is a platinum resistance thermometer, and the wire 3 is a high-temperature wire. The metal mounting base 1 has a mounting cavity 4. The temperature sensing element 2 is disposed in the mounting cavity 4 and electrically connected to the wire 3. The temperature sensing element 2 and its connection with the wire 3 are fixed in the mounting cavity 4 by potting adhesive 5.

[0031] In this embodiment, the connection between the temperature sensing element 2 and the wire 3 is wrapped with insulating tape 6. The insulating tape is made of high-temperature resistant insulating tape. After connecting the platinum resistance thermometer to the high-temperature wire, high-temperature insulating tape is applied to the bottom of the platinum resistance thermometer or the connection point between the platinum resistance thermometer and the high-temperature wire is wrapped with high-temperature insulating tape to ensure that the connection point is insulated from the metal mounting base 1, and then potting and fixing are performed.

[0032] In this embodiment, the metal mounting base 1 is cylindrical, but not limited to cylindrical; other shapes such as prisms are also possible.

[0033] In this embodiment, the metal mounting base 1 is made of stainless steel, but it is not limited to stainless steel; other metal materials such as carbon steel are also acceptable.

[0034] During installation, the metal mounting base 1 is directly welded and fixed to the measuring tube of the Coriolis mass flow meter.

[0035] This structure integrates the temperature sensing element 2 with the metal mounting base 1, and welds and fixes it to the measuring tube of the Coriolis mass flow meter. This effectively reduces the operational difficulty of installing the temperature sensor in the Coriolis mass flow meter, improves the convenience of installation and structural stability, and reduces costs.

[0036] Example 2

[0037] like Figures 3-5 As shown, this embodiment provides a temperature sensor structure for a Coriolis mass flow meter. The difference from the first embodiment is that a metal mounting plate 7 is fixedly provided on one side of the metal mounting base 1. The metal mounting plate 7 is welded and fixedly connected to the metal mounting base 1. The metal mounting plate 7 can be elastically deformed to fit onto the measuring tube 8 of the Coriolis mass flow meter.

[0038] In this embodiment, the thickness of the metal mounting plate 7 is less than 1 mm, preferably less than 0.5 mm, and more preferably 0.2 mm.

[0039] In this embodiment, the shape of the metal mounting piece 7 is rectangular, but it is not limited to a rectangle; other shapes such as triangles and circles are also acceptable.

[0040] In this embodiment, the metal mounting plate 7 is made of stainless steel, but is not limited to stainless steel; other metal materials such as carbon steel are also acceptable. Preferably, the metal mounting plate 7 is made of the same material as the metal mounting base 1.

[0041] During installation, the metal mounting plate 7 is attached to the measuring tube 8 of the Coriolis mass flow meter, and then the metal mounting plate 7 is fixed to the measuring tube 8 by welding, bonding or brazing.

[0042] This structure integrates the temperature sensing element 2 with the metal mounting base 1 and the metal mounting plate 7, placing them on the measuring tube 8 of the Coriolis mass flow meter. This effectively reduces the operational difficulty of installing the temperature sensor in the Coriolis mass flow meter, ensuring a closer fit to the measuring tube, improving installation convenience and structural stability. It can effectively measure fluid temperature with high accuracy. This structure offers advantages such as convenient installation, high stability, and more accurate measurement. The metal mounting plate 7 allows it to be used with measuring tubes 8 of any diameter, offering strong versatility and low cost.
