KX-H-FVP thermocouple signal line with K-type compensation wire, featuring fluoroplastic insulation and sheath.

Thermocouple Compensation Wire Details, Structure, and Definition: Thermocouple compensation wire, commonly referred to as compensation wire, is typically composed of alloy wire, insulation, sheath, and shielding layer. Within a certain temperature range (including ambient temperature), it consists of a pair of insulated wires with the same nominal electromotive force as the matched thermocouple. These wires are used to connect the thermocouple to the measuring device to compensate for the temperature variation errors at the joint between the thermocouple and the connection point.

Two: The use of compensating cables between thermocouples and measuring devices offers two advantages:

1. Enhance the physical and mechanical properties of thermocouple temperature measurement lines. Using multi-strand cores or small-diameter compensating wires can increase the flexibility of the lines, facilitate wiring, and adjust line resistance or shield external interference.

2. Reduce measurement line cost; when the thermocouple is far from the measuring device, using compensation wires can save a significant amount of thermocouple material, especially when using precious metal thermocouples, where the economic benefits are more pronounced.

Section 3: Terms and Symbols:

(1) Extended Compensation Wire: Also known as extended wire, the extended compensation wire has the same nominal chemical composition of the alloy wire and electromotive force (EMF) nominal values as the thermocouple it is paired with. It is denoted by the letter "X" appended after the thermocouple type, e.g., "KX" indicates an extended compensation wire for a K-type thermocouple.

(2) Compensation Compensation Wire: Also known as compensation wire, the nominal chemical composition of the alloy wire in compensation compensation wire is different from that of the thermocouple it is paired with. However, its electromotive force value is the same as the nominal value of the electromotive force of the paired thermocouple at 0-100℃ or 0-200℃. It is indicated by the letter "C" appended after the thermocouple type number, such as "KC". Different alloy wires can be applied to the same type number of thermocouples and are distinguished by additional letters, such as "KCA", "KCB". Currently, it is not widely used.

(3) Allowance: The allowance for thermocouple compensation wires is due to significant deviations in the measurement system caused by the use of compensation wires. This value is expressed in microvolts, and the size of the allowance is divided into precision and standard grades.

(4) Symbols: S - indicates precision-grade thermocouple compensation wire. No letter is marked for general-grade compensation wire; G - indicates general-purpose compensation wire; H - indicates heat-resistant compensation wire; R - indicates compensation wire with multi-strand core. No letter is marked for compensation wire with a single-strand core; P - indicates compensation wire with a shielding layer; B - indicates compensation wire with a jacket made of non-glass fiber material.

Note: The above basic models list the shielding methods for copper wire or tin-plated wire only; other shielding types can be changed by simply modifying the shielding code, such as P2, P3. For flame-retardant types, add "ZR" before the model number; for armored cable models, add "22" after the model number. ZR192 is an imported PFA material with a temperature resistance of 260°C.
