Abstract

The invention relates to a novel standard rhodium-iron resistance thermometer, which comprises a housing, a cross-shaped skeleton, lead wires and a rhodium-iron resistance wire, wherein the cross-shaped skeleton is arranged in the housing; the rhodium-iron resistance wire is wound on the cross-shaped skeleton; and the rhodium-iron resistance wire is led out through the lead wires. The novel standard rhodium-iron resistance thermometer adopts the cross-shaped skeleton to wind the wire and is capable of realizing both temperature sensing wire support and free telescoping; the thermometer is good in stability, stable in structure, and high in resistance to vibration and impact; the skeleton is made of a quartz material, wherein the material is stable in components and does not pollute the resistance wire; and temperature measurement and temperature control stability of the standard rhodium-iron resistance thermometer can be kept for a long term.

Description

technical field [0001] The invention relates to a standard thermometer, in particular to a novel standard rhodium-iron resistance thermometer. Background technique [0002] At present, according to the definition of the International Temperature Scale (ITS-90) in 1990, in the temperature zone below 24.5561K: the interpolation instrument in the temperature zone of 0.65K-5.0K is a helium vapor pressure thermometer, and the interpolation instrument in the temperature zone of 3.0K to 24.5561K It is an inline helium gas thermometer. As we all know, vapor pressure thermometers and gas thermometers must have a warm bubble to feel the temperature. The device is complex and requires precise measurement of pressure. It takes a long time for these two thermometers to reach the balance of temperature and pressure, and many parameter corrections are required. It is extremely inconvenient, and it is very difficult to reproduce the temperature scale. Therefore, in the temperature range b...
