Description：
An overview, cables:
Compensation wires and compensation cables, to a certain temperature range (including temperature) with the matched the thermocouple thermoelectric emfs values the same couple or more with insulated wire or cable, use them to connect the thermocouple and measuring devices, to compensate them with the error produced by the temperature change of the thermocouple junction, compensation wires and compensation cables are divided into extension type and compensation type two kinds, fluorine plastic wire or cable and silicon rubber insulation resistance to high temperature compensation is more high temperature resistant, cold resistant, resistant to acid and alkali oil and water, don't delay burning, anti-aging and other advantages, the products are widely used in petroleum, chemical industry, electric power, metallurgy, medicine, textile and other factories and scientific research departments in the temperature measurement and control system.
Second, the compensating conductor standards:
GB/T4989-94 (equivalent to the IEC584-3 standard)
Three, compensation conductor used features:
1, the highest working temperature conductor: 70 ℃ polyvinyl chloride (PVC) 200 ℃ and 180 ℃ 105 ℃ silicone rubber fluorine plastic meltability polytetrafluoroethylene (PTFE) 260 ℃
2, the lowest temperature:
PVC sheathed: fixed installation to 40 ℃, the fixed installation to 15 ℃.Fluorine plastic and silicone rubber sheath: fixed installation - 60 ℃, the fixed installation - 20 ℃.
3, cable allows bending radius: the minimum armored cable is 6 times of overall diameter;Copper tape screened or steel tape armoured cable minimum 12 times of cable diameter;Fluorine plastic insulation and sheath minimum 10 times of cable diameter.
Four, compensation conductor should be the basic model and name:

Note: 1, the above models only list the KX, other such as SC, KC, EX, BC, TX, JX need to change the first model;
2, before this Ann model compensating cable type charging "ia";
3, flame retardant, compensation cable type filling before "out";If you need armoured can refill "22" after the model;If you want to block, can indicate shielding in style: P, P1 tin plated copper wire, copper wire P2 copper strip, P3 lu: su composite film;Conductor for multiple strands of soft core, should inject "R" after the model.
4, PTFE ZR190 for imported materials, heat-resistant 260 ℃.
Five, compensation conductor should be the main technical indicators:
Compensation conductor model | With thermocouple | Thermocouple index number | Compensating lead wire | Insulating layer coloring | ||
The anode | The cathode | The anode | The cathode | |||
SC | 10 - platinum platinum rhodium thermocouple | S | SPC (copper) | SNC (copper, nickel) | red | green |
RC | 13 - platinum rhodium platinum thermocouple | R | RPC (copper) | The RNC (copper, nickel) | red | green |
KCA | Nickel chrome - nickel silicon thermocouple | K | KPCA (iron) | KNCA (copper, nickel) | red | blue |
KCB | Kleiner perkins caufield & byers (copper) | KNCB (copper, nickel) | red | blue | ||
KX | KPX (nickel chrome) | KNX (nickel silicon) | red | black | ||
NC | Nickel chromium silicon - nickel silicon thermocouple | N | NPC (iron) | NNC (copper, nickel) | red | grey |
NX | NPX (nickel chromium silicon) | NNX (nickel silicon) | red | grey | ||
EX | Copper nickel chrome - nickel thermocouple | E | EPX (nickel chrome) | ENX (copper, nickel) | red | brown |
JX | Iron, copper and nickel thermocouple | J | JPX (iron) | JNX (copper, nickel) | red | The purple |
TX | Copper, copper nickel thermocouple | T | TPX (copper) | TNX (copper, nickel) | red | white |
Note: type the first letter and the thermocouple corresponding to the index, the second letter in "C" said compensation conductor, the letter "X" said compensation conductor should be extended type.SC type can be compensation conductor with R type degree thermocouple.
