Problems solved by technology
[0002] Thermocouple is a conventional temperature detection instrument, which is generally used for high temperature detection. Due to the high ambient temperature, the thermocouple core and thermode of the thermocouple will become soft due to high temperature, and its mechanical strength will decrease accordingly. Electrodes are often disconnected and fall, which affects production. Since the thermal electrode material is made of precious metals, the economic loss caused by frequent damage is relatively large, especially in industrial environments with high vibration such as rotary kilns.

The invention provides a protective sleeve and a thermocouple, wherein the protective sleeve comprises: an insulating tube, and two first through holes symmetrical about the central axis of the insulating tube are opened on the side wall of the first end of the insulating tube; The wiring seat, the wiring seat is provided with a mounting hole, the side wall of the mounting hole is provided with two second through holes symmetrical about the central axis of the mounting hole, the first end of the insulating tube is located in the mounting hole, and the two first The piercing holes correspond to the two second piercing holes; the first fixing piece is pierced through each first piercing hole and each second piercing hole, and fixes the insulating tube and the wiring seat. In the present invention, the first fixing member passes through the insulating tube and the wiring seat, and fixes the insulating tube on the wiring seat like a beam, so that the connection between the insulating tube and the wiring seat is more firm, and the falling of the insulating tube is avoided, thereby avoiding The falling of the electrode installed in the insulating tube is prevented, the normal production is ensured, and the economic loss caused by the falling of the electrode is also avoided.
Description
technical field [0001] The invention relates to the technical field of thermocouple sensors, in particular to a protective sleeve and a thermocouple. Background technique [0002] Thermocouple is a conventional temperature detection instrument, which is generally used for high temperature detection. Due to the high ambient temperature, the thermocouple core and thermode of the thermocouple will become soft due to high temperature, and its mechanical strength will decrease accordingly. Electrodes are often disconnected and fall, which affects production. Since the thermal electrode material is made of precious metals, the economic loss caused by frequent damage is relatively large, especially in industrial environments with high vibration such as rotary kilns. . Contents of the invention [0003] In view of this, the present invention proposes a protective sleeve and a thermocouple, aiming at solving the current problem of thermode breakage. [0004] In one aspect, the pr...
