Description
Technical field
The present invention relates to temperature sensor field, more particularly to a kind of high-temperature sensitive ceramic armouring pyrometer couple and its
Manufacture method.
Background technology
For the Thermal-resistance tool Heat-Treatment of Steel such as heat resisting steel and high-speed steel (treatment temperature typically 1100 DEG C -1350 DEG C it
Between) when, it is only capable of at present using platinum rhodium thermocouple (B idols, S occasionally R idols) as heat treatment thermometric idol, according to American army mark AMS
The requirement of 2750E, needs altogether three thermocouples even as normalization, it is well known that platinum rhodium thermocouple price during high-temperature heat treatment
Expensive (armouring platinum rhodium single of wholesale price of idol is minimum 1500 yuan, also only the S idols of rhodium-containing 10%), therefore be further increased
Financial cost.More it is to be noted that in fact domestic platinum rhodium thermocouple routine is typically only capable of reaching 1200 DEG C using temperature, length
Shi Chaowen will be substantially reduced using its service life and performance；And it is typically used as the even nickel chromium triangle silicon-nisiloys of N, although cheap,
Durable, reliability is high, and theory uses temperature, but its at high temperature the characteristic of oxidizable failure be allowed to cannot be at conventional high temperature heat
Used in reason, less than 1100 DEG C thermometrics are typically only used for.
In the Patents applied at home, also not by nickel chromium triangle silicon-nisiloy thermo wires for pyrometric patent money
