Example Embodiment

[0012] Such as Figure 1~4 Shown: the high-precision temperature sensor detection special heat collection device of the present invention includes a mounting plate 5 and a copper column 1 located below the mounting plate 5, and a standard device insertion tube 3 and a sensor are provided between the mounting plate 5 and the copper column 1 Insert tube 4.
[0013] The lower ends of the standard instrument insertion tube 3 and the sensor insertion tube 4 are inserted into the copper column 1 and are fixedly connected to the copper column 1 by welding, bonding or fastening. The lower ends of the etalon insertion tube 3 and the sensor insertion tube 4 are close to each other.
[0014] The upper ends of the etalon insertion tube 3 and the sensor insertion tube 4 and the mounting disk 5 are fixedly connected by welding and are evenly distributed in the circumferential direction. The upper ports of the etalon insertion tube 3 and the sensor insertion tube 4 are exposed from the mounting disk 5. Mounting bolts 7 are provided on the mounting plate 5.
[0015] The mounting plate 5 has an annular inclined surface 6 on the upper surface. The longitudinal axis of the standard inserting tube 3 and the sensor inserting tube 4 are perpendicular to the inclined surface 6; a connecting plate is welded and fixed on the standard inserting tube 3 and the sensor inserting tube 4 2.
[0016] Such as Figure 5 Shown: the high-precision temperature sensor detection special heat collector of the present invention, when used, the mounting plate 5 is fixed to the upper cover of the box body 8 through the mounting bolts 7, the copper column 1 is located in the inner cavity of the box body 8, and the agitator 9 is in the box At the bottom of the inner cavity of the body 8, the temperature measurement end of the standard device is inserted into the standard device insertion tube 3, and the temperature measurement end of the temperature sensor to be measured is inserted into the sensor insertion tube 4, so that the temperature measurement ends of the standard device and the temperature sensor are located on the copper column 1 Internally, it is ensured that the temperature measuring terminals of the standard and the sensor are close to each other, and the temperature signal is collected at almost the same position, so it has the advantages of simple structure, close temperature collection position, small error and accurate detection.
