Thermocouple compensation code

Application of compensation wires and cables for thermocouples: Compensation wires and cables for thermocouples are suitable for single or multi-point connection of automatic thermometers in industries such as power, metallurgy, petroleum, chemical, textile, as well as national defense, scientific research and other departments. Product standard: Thermocouple compensation code: GB/T4989-94 Usage characteristics: Usage temperature: Heat resistance level: -65 ℃~+200 ℃ and -65 ℃~+260 ℃, 2 ordinary levels: -40 ℃~+70 ℃ and -40 ℃~+105 ℃, 2 types. Minimum bending radius: Compensation wire: more than 8 times the outer diameter of the conductor. Compensation cable: more than 12 times the outer diameter of the cable when there is a sheath, and more than 12 times the outer diameter of the cable when there is no sheath; The compensating wire form, alloy wire material, and insulation color model thermocouple index number are: wire alloy wire insulation layer coloring positive electrode BC B platinum rhodium 30 platinum rhodium 6 copper gray SC S platinum rhodium 10 platinum SPC (copper) SNC (copper nickel 0.6), red green RC R platinum rhodium 13 platinum RPC (copper) RNC (copper nickel 0.6) compensated by thermocouple red green KCA K nickel silicon KPCA (iron) KNCA (copper nickel 2) red blue KCB KPCB (copper nickel 4) red blue KX KPX (nickel chromium 10) KNX (nickel silicon 3) red black NC N nickel silicon NPC (iron) nn red gray NX NPX (nickel chromium 14 silicon) NNX (Nickel Silicon 4) Red Grey EX E Nickel Silicon Nickel Silicon EPX (Nickel Chromium 10) ENX (Copper Nickel 45) Red Brown JX J Iron Copper Nickel JPX (Iron) JNX (Copper Nickel 45) Red Purple TX T Copper Nickel TNX (Copper Nickel 45) Red and White WC3/25 WRe3-WRe25 Tungsten Tungsten Rhenium 25 WPC3/25 WNC3/25 Red Yellow WC5/26 WRe5-WRe26 Tungsten Rhenium 5-Tungsten Rhenium 26 WPC5/26 WNC5/26 Red Orange&# 8226; Classification of compensation wire usage and color of protective layer usage, accuracy level and identification of protective layer coloring, ordinary level, precision level, ordinary use, G/S black, gray, heat-resistant use, H/S black, yellow&# 8226; Compensation wire allowable tolerance and reciprocating resistance compensation wire type reciprocating resistance at 20 ℃&Omega/ M is 0.2 mm 20.5 mm 21.0 mm 21.5 mm 22.5 mm 2n c or BC0 250.100.050.030.02 kca3. 50.400.700.47kcb2. 60.400.700.470.28kx5.
