Thermal resistor thermometer test system multi-purpose tray and insert plate device

Abstract

The invention comprises a main support insert disk, side-opening jacks of a special joint thermal resistor to be detected, a guide holding tube of a standard thermometer, a guide holding tube of a thermometer to be detected, a positioning insert plate of the special joint thermal resistor to be detected, a rotary lifting righting clamp, a connection plate and annular collets. Three side-opening jacks of the special joint thermal resistor to be detected are uniformly distributed on the main support insert disk, the annular collets and a coiled clip reed are provided below the jacks, and an insert plate guide base is arranged on both sides of the side-opening jacks. The guide holding tube of the thermometer to be detected is provided below the main support insert disk, and the rotary lifting righting clamp is arranged on the guide holding tube of the standard thermometer. The thermometer of a thermal resistor to be detected can be detected by arranging in the guide holding tube, disposing in a constant-temperature bath and adjusting the height of the lifting righting clamp to fix the thermometer. The invention has the advantages of safe and reliable operation, high work efficiency, good thermostatic performance and accuracy detection.

Description

technical field [0001] The invention relates to an instrument for measurement verification, in particular to a multi-purpose tray device for a thermal resistance thermometer verification system. Background technique [0002] Medium and low temperature is an important technical index that cannot be ignored in the fields of national defense, shipbuilding, smelting, science and technology, industry and agriculture, metrology, archives, medical treatment, scientific research, etc. At present, there are hundreds of professional factories producing medium and low temperature systems in the domestic market. The tray device on the oil, water, and low-temperature constant temperature baths used can only test conventional or general-purpose thermal resistance thermometers, but cannot test the temperature-sensitive part with only 30-50mm special connectors and special temperature bulbs. , even if the verification, the result is basically unqualified, and it is not suitable for the veri...

[0002] Medium and low temperature is an important technical index that cannot be ignored in the fields of national defense, shipbuilding, smelting, science and technology, industry and agriculture, metrology, archives, medical treatment, scientific research, etc. At present, there are hundreds of professional factories producing medium and low temperature systems in the domestic market. The tray device on the oil, water, and low-temperature constant temperature baths used can only test conventional or general-purpose thermal resistance thermometers, but cannot test the temperature-sensitive part with only 30-50mm special connectors and special temperature bulbs. , even if the verification results are basically unqualified, it is not suitable for the verification of Kaizhuang thermal resistance and Wushu temperature bulb thermometers of various joints, and it cannot meet the growing needs of modern industry
