In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
In the description of the present application, it is to be understood that the orientation or positional relationship indicated by the directional terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc., is typically an orientation or positional relationship based on a coordinate system shown in the front view of the device itself or the corresponding sub-component, and that the set of coordinate systems will not rotate with it when other directional views are discussed.

Generally, the measurement precision is higher. The thermometer can also measure the temperature distribution inside the object within a certain temperature measuring range. However, a large measurement error occurs in a moving body, a small target, or an object having a small heat capacity, and commonly used thermometers include a bimetal thermometer, a glass liquid thermometer, a pressure type thermometer, a resistance thermometer, a thermistor, a thermocouple, and the like. They are widely used in industrial, agricultural, commercial, etc. sectors. These thermometers are also commonly used by people in everyday life.

The low temperature thermometer requires the temperature sensing element to be small in size, high in accuracy, good in reproducibility and stability. A carburized glass thermal resistor formed by carburizing and sintering porous high silica glass is a temperature sensing element of a low-temperature thermometer and can be used for measuring the temperature within the range of 1.6-300K.
