Background technology
Along with making rapid progress of the industrial enterprise such as national energy, metallurgy, oil, chemical industry and scientific research department, the control of material property, mechanical work equitemperature is required more and more higher by plant machinery and research and development department, the birth of monitoring compensating cable certainly will be caused, and as in the limited local space of R&D institution, the occupancy volume in cable space be it is also proposed new requirement, squashed structure arises at the historic moment, the effect of compensating cable extends multiple spot thermode and the cold end of mobile thermocouple, couples composition multi-point temperature measurement system with display instrument.It is in certain temperature range, has the wire of a pair tape insulation cladding identical with the thermo-electromotive force nominal value of thermocouple coupling, and its effect only plays extension thermode, makes the cold end of thermocouple move on the instrument terminals of control room.But existing cable transmission is accurate not, easily causes relevant device and produce fault, and and then easily personnel are damaged.
Summary of the invention
For overcoming the defect of prior art, the utility model proposes a kind of reinforced high temperature resistant monitoring fine compensation strip conductor, this cable have sensing control temperature accurately, use temperature range width, heat resisting, anti-soda acid, installation flexible, easy, take up room the characteristics such as little, lightweight, strong interference immunity.
For achieving the above object, the utility model proposes a kind of reinforced high temperature resistant monitoring fine compensation strip conductor, nexine outer layers include conductor, insulating barrier, core band, screen layer, sealing coat one, restrictive coating, sealing coat two and outer jacket successively；Described conductor is the mild alloy conductor of seven bursts of stranded compositions of B alloy wire；Described insulating barrier is to extrude polytetrafluoroethylmaterial material on mild alloy conductor；Described core band is the polyester belt that two positive and negative class B insulation cores are the most wrapped；Described screen layer is that outside polyester belt, count is the anaerobic soft copper silk of 85%；Described sealing coat one is the glass fibre belt outer wrapped one layer of screen layer；Described restrictive coating is to extrude one layer of thin polytetrafluoroethylsheath sheath line outside glass fibre belt；Described sealing coat two is at the outer wrapped layer of glass fiber band of restrictive coating；Described outer jacket is the pyroceram silk fiber in fiberglass layer external chiasma braiding.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, conductor uses micron order KX offset-type B alloy wire, and micron order franchise is ± 60(± 1.5 DEG C), thermocouple measurement end temperature reaches 900 DEG C.
2, insulation uses import politef to be insulant, has insulation thin, lightweight, good insulating, resistant of high or low temperature, and using temperature range is-50 DEG C～250 DEG C.
3, the soft proof copper-wire braided of screen layer, count is up to 85%, and shielding rejection coefficient is excellent, and the anti-external world is effective, to the monitoring of temperature sensing control accurately.
4, both positive and negative polarity core is parallel, reduces production process, and installation takes up room little, convenient and swift.
5, isolation band all uses resistant to elevated temperatures glass fibre belt, improves the use temperature of product.
6, outer layer uses polytetrafluoroethylsheath sheath and glass fiber interlacing, forms dual reinforcement sheath, has widened use ambient temperature, and the most dual sheath adds its environment resistant (acid and alkali corrosion).
Accompanying drawing explanation
