Compensating wire K-type ZR-KC-FVP-2*1.5 thermocouple sensor temperature measurement extension wire

Detailed Explanation of Thermocouple Compensation Wire, 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 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, thus reducing errors.

Two: Using compensation wires between thermocouples and measuring devices has 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 line, facilitate wiring, and also adjust the line resistance or shield external interference.

2. Reduce measurement line costs; 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 even more pronounced.

III. 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 denoted by the letter "X" appended after the thermocouple type number, e.g., "KX" indicates an extended compensation wire for a K-type thermocouple.

(2) Compensation Compensation Wire: Also known as Compensation Wire, this type has an alloy wire with a nominal chemical composition different from that of the thermocouple it is paired with. However, its electromotive force value is the same as the nominal value of the thermocouple's electromotive force 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 used for the same type number thermocouple, distinguished by additional letters, like "KCA", "KCB". Currently, it is not widely used.

(3) Allowance: The allowance for thermocouple compensation wires is due to the large deviation caused by the compensation wire in the measurement system. This value is expressed in microvolts, and the size of the allowance is divided into precision grade and ordinary grade.

(4) Symbols: S - indicates precision grade thermocouple compensation wire. No letter is marked for general grade compensation wire; G - indicates general use compensation wire; H - indicates heat-resistant compensation wire; R - indicates compensation wire with multi-strand cores. No letter is marked for compensation wire with a single strand core; 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.

Note: The above basic models only list copper wire or tin-plated wire shielding methods. Other shielding type models only need to change the shielding code, such as adding "ZR" before the model number for flame-retardant type P2, P3, adding "22" after the armored cable model number, ZR192 is an imported PFA material with a temperature resistance of 260°C.
