Abstract
This utility model discloses the platinum resistance of a kind of high-temperature-resistant and anti-corrosion, is made up of ceramic substrate, platinum sheet and lead-in wire.Platinum sheet sticks in ceramic substrate finish side, and lead-in wire welds with the pad of platinum sheet, and joint uses glass paste sealant to seal so that it is resistance to gentle corrosion resistance improves.Ceramic substrate, platinum sheet, the lead-in wire and the platinum strip terminal that seal through glass paste sealant, be encapsulated in alloy anticorrosion shell.Lead-in wire use chemical reinforced platinum wire, in chemical reinforced platinum wire add wolfram element, can heatproof to 1200 DEG C；SiO in glass paste sealant2Not reinforced with chemistry platinum wire reacts, thus improves use temperature and the corrosion resistance of overall platinum resistance.
Description
Technical field
This utility model belongs to electronic component technology field, relates to resistance, the platinum of a kind of high-temperature-resistant and anti-corrosion
Resistance.
Background technology
Platinum resistance, its resistance can change along with the change of temperature, and resistance can form at the uniform velocity along with temperature rises
Rise.Current most of platinum resistance use split-type structural, and sealing is inadequate, and particularly during pyrometry, platinum resistance pin holds very much
Easily contact with external environment, cause the insulation resistance value between platinum resistance and housing not reach requirement, even go out between platinum resistance two pins
Existing short circuit, causes temperature sensor resistance value inaccurate, thus causes thermometric inaccurate.Additionally, platinum resistance temperature sensor
Housing uses aluminium material, and corrosion resistance is bad, is easily corroded during long-time use；Most platinum resistance sensing parts and sensor
Housing contact is bad, and warming answers speed slow.
Utility model content
This utility model is for solving the deficiencies in the prior art, it is provided that the platinum resistance of a kind of high-temperature-resistant and anti-corrosion, employingization
Learn reinforced platinum wire material as lead-in wire, make the resistance to gentle corrosion resistance of platinum resistance improve.
The technical solution of the utility model is as follows:
The platinum resistance of a kind of high-temperature-resistant and anti-corrosion, is made up of ceramic substrate, platinum sheet and lead-in wire.
Platinum sheet sticks in ceramic substrate finish side, and lead-in wire welds with the pad of platinum sheet, and joint uses glass
Slurry sealant seals so that it is resistance to gentle corrosion resistance improves.Ceramic substrate, platinum sheet, through glass paste sealant seal
Lead-in wire and platinum strip terminal, be encapsulated in alloy anticorrosion shell.
Further, lead-in wire uses chemical reinforced platinum wire, adds wolfram element so that it is be resistant in chemical reinforced platinum wire
Temperature is to 1200 DEG C.
Further, the SiO in glass paste sealant2Not reinforced with chemistry platinum wire reacts, thus improves overall platinum electricity
The use temperature of resistance and corrosion resistance.
Effect of the present utility model and benefit be:
(1) platinum resistance of this high-temperature-resistant and anti-corrosion, adds wolfram element and it can be made resistance in the most chemical reinforced platinum wire
1200 DEG C of high temperature；
(2) SiO in glass paste sealant2Not reinforced with chemistry platinum wire reacts, thus improves overall platinum resistance
Use temperature and corrosion resistance.
Accompanying drawing explanation
The platinum resistance structural representation of Fig. 1 high-temperature-resistant and anti-corrosion.
Fig. 2 reinforced platinum wire of chemistry and platinum sheet connection diagram.
In figure: 1 ceramic substrate；2 platinum sheets；3 lead-in wires；4 glass paste sealants.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
The platinum resistance of a kind of high-temperature-resistant and anti-corrosion, as shown in Figure of description 1, by ceramic substrate 1, platinum sheet 2 with draw
Line 3 forms.Platinum sheet 2 sticks on ceramic substrate 1, and the lead-in wire 3 chemical reinforced platinum wire of employing, lead-in wire 3 welds with platinum sheet 2
Connecing, as shown in Figure of description 2, joint uses glass paste sealant 4 to seal so that it is resistance to gentle corrosion resistance improves.
The platinum resistance of high-temperature-resistant and anti-corrosion can be as the core parts of platinum resistance thermometer, and it is right to need before using to carry out
Its structural intergrity checks, and needs the platinum resistance to high-temperature-resistant and anti-corrosion to carry out standard calibration.
Figure of description is only used as the structure of product, principle schematic, actual product structure and size and designs with inventor
Production drawing is as the criterion.
Embodiment described above is only to be described embodiment of the present utility model, not to this utility model
Spirit and scope be defined.On the premise of without departing from this utility model design concept, this area ordinary person is to this reality
The various modification made by novel technical scheme and improvement, all should drop into protection domain of the present utility model, and this practicality is new
The scope of type is limited by claims rather than described above.
