Thermocouple with compensation, compensation cable wire
Products overview:
Thermocouple with compensation wire, compensation cable thermal electrode is used to extend the movement of the thermocouple cold end, and display instrument connection temperature measuring system.This product USES the GB/T 4989-94 the thermocouple with compensation lead national standards (equivalent to the IEC584-3, the third part the thermocouple compensation wire, international standards), insulation layer and protective layer selects the import high quality fluorine plastic, and USES the new technology of the continuous extrusion, make the product has excellent acid, alkali, wear resistance and non-combustible delay of performance, can be immersed in oil and water medium and long term use.Using temperature - 60-205-260 ℃, belong to the contemporary international advanced level.Products are mainly applied to all kinds of temperature measurement device, has been widely used in petroleum, chemical industry, metallurgy, electric power and other departments.
Second, the scope of application:
Thermocouple with compensation wire, compensation cable is suitable for the index number is S, R, K, E, N, E, T, J of thermocouple type and temperature display instrument of electrical connections between, is widely used in electric power, metallurgy, petroleum, chemical industry and so on national defense scientific research departments such as thermal temperature automatic control, with a line to block and total shielding of the cable, can effectively prevent outside interference, improve the temperature measuring accuracy.
Flame retardant compensation cable (wire) is mainly used for fire to demand higher occasion.Keep the product with voltage grade, with specifications of ordinary cable all performance indicators, such as: high mechanical and physical properties, excellent electrical properties and chemical corrosion resistance, etc., and flame retardant properties, avoid the spread of caused by cable fire, reducing the huge losses of life and property.
Low smoke low halogen flame retardant compensation cable (wire) in addition to keep the flame retardant cable outside the general properties and electrical performance also have less smoke when burning, the characteristics of small amount of hydrogen chloride gas release and low corrosive.
Low smoke zero halogen flame retardant compensation cable (wire) besides can satisfy the using demand of the flame retardant cable, but also has no halogen acid gas release, smoke less, produce less corrosive gas, good flame retardant performance characteristics.
Fluorine plastic insulation and sheath compensation cable (wire) has excellent heat resistance, anti-corrosion, acid and alkali, chemical resistance, abrasion resistance, oil resistance, ageing resistance and combustion performance.
Silicone rubber sheath compensation cable (wire) with softness.
The Ann model compensating cable (wire) also have explosion-proof features, applicable to chemical and petrochemical environment measurement and control system of gas and dust explosion and the Ann circuit.
Three, thermocouple compensation wire, compensation cable main technical indicators:
Compensation conductor model according to the varieties of products are classified into SC, KC, KX, EX, JX, TX, NC
Among them: a) model is the first letter and the thermocouple index number corresponding;
B) the letter "X" said expanded compensation conductor type (don't);
C) the letter "c" type compensation wires (don't).
Note: type SC can be compensation conductor with R type degree thermocouple
Fourth, using features:
Cable long-term allowed working temperature of conductor: heat resistant level does not exceed 200 ℃ and 260 ℃.Regular grade up to 70 ℃, 90 ℃ and 105 ℃.
Five, the cable lowest environment temperature:
Fluorine plastic insulation and sheath compensation cable to 60 ℃ fixed;The fixed installation - 20 ℃.
Polyvinyl chloride (PVC) plastic insulated and sheathed compensation cable to 40 ℃ fixed;The fixed installation to 15 ℃.
Silicone rubber sheath cable to 60 ℃ fixed;The fixed installation - 20 ℃.
Six, the recommended allows bending radius:
Polyvinyl chloride (PVC) plastic insulated and sheathed compensation no armoured layer of the cable, cable should be not less than 10 times of cable diameter;Fluorine plastic insulation and sheath compensation no armoured layer of the cable, cable should be not less than 10 times of cable diameter;Armoured layer compensation cable, should not be less than 12 times of the cable.
