Compensating wire K-type KX-H-FV-2*1.5 thermocouple temperature sensing extension cable.

Detailed Explanation of Thermocouple Compensation Wire, Structure and Definition: Thermocouple compensation wire, commonly referred to as compensation wire, is typically composed of compensation wire alloy wire, insulation, sheath, and shielding layer. Within a certain temperature range (including room temperature), it consists of a pair of insulated wires with a nominal electromotive force (emf) value identical to that of the matched thermocouple. These wires are used to connect the thermocouple to the measuring device to compensate for the temperature variations at the connection point with the thermocouple, thereby reducing errors.

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 improve the flexibility of the lines, facilitate wiring, and also adjust line resistance or shield external interference.

2. Reduce the cost of measurement circuitry; when the thermocouple is far from the measuring device, the use of compensating cables 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 value as the thermocouple it is paired with. It is indicated 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 the 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 distinguished by additional letters, such as "KCA", "KCB". Currently, it is not widely used.

(3) Tolerance: The tolerance of the thermocouple compensating cable is due to significant deviations caused by the compensating cable in the measurement system. This value is expressed in microvolts, with two levels of tolerance: precision grade and standard grade.

(4) Symbols: S - indicates precision class thermocouple compensation wire. No letter is marked for general class compensation wire; G - indicates general use compensation wire; H - indicates heat-resistant compensation wire; R - indicates compensation wire with multi-strand core. No letter is marked for single-strand core compensation wire; P - indicates compensation wire with a shielding layer; V - indicates insulation or sheath made of polyvinyl chloride (PVC); F - indicates insulation made of polytetrafluoroethylene; B - indicates sheath made of non-glass fiber material.
