Description
Technical field
The utility model relates to a kind of stripping temperature detection techniques, and in particular to a kind of good armored cable temperature of insulation performance
Spend sensor.
Background technique
It is generally known that plastics or rubber can be used and sensed as low temperature being no more than 300 DEG C of temperature detection occasion
The insulation of device or sealing material, but when temperature be more than 300 DEG C it is necessary to use high-temperature insulation object fill, metal entirety armouring
Conductive cable, i.e. armored cable makes temperature sensor.
Foreign countries for K-type thermocouple to armored cable protective metal shell alloying component existing research (CN88102259A), but it is right
In thermoelectricity of the long-term operating temperature under 1000 DEG C of environment occasionally temperature sensor, which will be in manufacture and cost
There is obvious disadvantage.
Country's armored cable protective metal shell material is SUS310 (S) or Inconel600 at present, and conductive core line material is
Nickel or chromium, high-temperature insulation filler material are MgO powder of the purity 99.6% or more.But due to the stronger moisture absorption of MgO
Property, armored cable, which is stored under indoor environment, easilys lead to insulation resistance reduction, and then influences properties of product.
Mass production it was verified that high temperature sensor Insulation Problems largely appear in armored cable tail portion, due to
Armored cable core wire is thinner, and exposed portion easily deforms under vibration and micro-displacement, and insulation performance is caused to reduce.
Domestic high temperature sensor tail portion generallys use rolling-trough type necking, and the tightening mode of line contact cannot be guaranteed to sense
The good leakproofness of device long-time.
