Abstract
The utility model discloses a katathermometer mounting base which comprises a base body. The katathermometer mounting base is characterized in that a thermometer mounting hole is formed in the middle of the base body; one end of the mounting hole is connected with the internal threads of a screw used for fixing the thermometer; and the other end of the mounting hole is connected with a vent hole. The katathermometer mounting base enables the thermocontact between the thermometer and a unit under test to be very reliable, and ensures the accuracy of the temperature measurement by long-term and stable fixation.
Description
Technical field
The utility model belongs to a kind of base, specifically is a kind of low-reading thermometer mounting seat.
Background technology
In the EAST of plasma physics research institute of the Chinese Academy of Sciences experimental provision, used a large amount of Cernox temperature sensor-AA cryogenic temperature sensors, this thermometer in use, must guarantee thermo-contact very reliably, and long-term installation stability, could guarantee measuring accuracy.The safe operation of the precision direct relation auto levelizer of this thermometer measure.In use, owing to be difficult to guarantee between thermometer and the unit under test good thermo-contact is arranged, owing to expand with heat and contract with cold, thermometer can break away from mounting hole in long-term use simultaneously, thereby causes temperature survey inaccurate.
The utility model content
The purpose of this utility model provides a kind of low-reading thermometer mounting seat, and making has thermo-contact very reliably between thermometer and the dut temperature parts, and can be steady in a long-term fix guaranteed temperature measurement accuracy.
The technical solution of the utility model is as follows:
A kind of low-reading thermometer mounting seat comprises pedestal, and it is characterized in that has the thermometer mounting hole in the middle of the described pedestal, and described mounting hole one end is connected with the Luo silk inner thread of fixed thermometer, and the described mounting hole other end is connected with air hole.
Described pedestal is a rectangular parallelepiped, and the rectangle face is installed on the measured object.
Thermometer mounting hole of the present utility model and Cernox temperature sensor-AA type thermometer are joined and are beaten, and guarantee that mounting hole and thermometer are in conjunction with closely.The custom-designed screw internal thread of mounting hole one end has guaranteed that Cernox temperature sensor-AA type thermometer in long-term use, can not break away from mounting hole.The air hole of the mounting hole other end guarantees that thermometer in insertion and vacuum, can not break away from mounting hole.And select conduct of rectangle face and the machined surface that tested position matches, can guarantee maximum contact area.Form thermo-contact very reliably, fixed form steady in a long-term is arranged, thereby guaranteed temperature measurement accuracy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of low-reading thermometer mounting seat comprises pedestal 1, and it is characterized in that has thermometer mounting hole 2 in the middle of the described pedestal 1, and described mounting hole 2 one ends are connected with the Luo silk inner thread 3 of fixed thermometer, and described mounting hole 2 other ends are connected with air hole 4.Pedestal 1 is a rectangular parallelepiped, and rectangle face 5 is installed on the measured object.
During use Cernox temperature sensor-AA thermometer is put in the supporting mounting hole of pedestal, and coat special heat transfer agent at the thermometer outside surface, increase surface of contact, penetrate fixing screw behind the lead-in wire overcoat insulation tube with thermometer then, screw is screwed on these parts, guarantees that thermometer is fixing reliable.Adopt the silver-bearing copper weldering to connect this base and unit under test then.Well guaranteed measuring accuracy from stability and thermo-contact aspect.
