Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of temperature constant temperature equipment verification and calibration, and relates to a temperature field test bracket for a dry-type temperature calibration furnace. Background Art
[0002] The dry-block temperature calibration furnace is mainly used for on-site verification and calibration of temperature sensors such as industrial platinum-copper thermal resistors, armored thermocouples, and low-cost metal thermocouples. In the operation of industrial production sites, temperature sensors are instruments for monitoring the temperature of measuring points. Generally, there is no major overhaul or shutdown period. The temperature sensors are not completely disassembled to the laboratory for metrological verification or calibration. With the operation of production site equipment, it is necessary to perform regular maintenance and fault inspection on temperature instruments. The dry-block temperature calibration furnace is small in size, heats up quickly, has high stability and is easy to move. Therefore, as a constant temperature device that provides a heat source, it can be used for on-site temperature measurement at the production site. The dry-block temperature calibration furnace can be used as a standard device to transfer temperature values at the production site. Its own temperature field needs to be tested and calibrated by a standard thermometer. In order to ensure the reliability and stability of the on-site measurement of the dry-block temperature calibration furnace, its temperature field performance should be tested regularly.
[0003] The standard thermometer commonly used in the temperature field test of the dry-block temperature calibration furnace is the standard platinum resistance thermometer. The standard platinum resistance thermometer is generally 480mm or longer, and the lead length is about 1.5m. The well depth in the dry-block temperature calibration furnace is generally 200m. Therefore, after the standard thermometer is placed in the furnace, most of its length is outside the furnace. When performing the axial temperature field test, the insertion depth of the standard thermometer will be further reduced, which has the risk of instability. Moreover, after the lead is connected to the electrical measuring equipment, most of it hangs on the ground, which is not conducive to the correct and safe use of the standard thermometer. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a temperature field test bracket for a dry-type temperature calibration furnace, which can ensure the safe fixation of the standard thermometer used in the test and make the temperature field test more convenient.

[0008] It also includes an adjusting bolt. The fixing clamp is provided with a second through hole, and the adjusting bolt passes through the through hole.
[0009] The fixing clip is made of rubber.
[0010] The base is provided with a blind hole for inserting the lower end of the metal rod.
[0011] The first supporting rod is perpendicular to the metal rod.
