Fiberglass Insulated Thermocouple Extension Cable With 7/0.2mm Conductor Used For Connecting Sensor And temperature Instrument
Thermocouple extension / compensation wire is a wire made of an alloy material with similar thermoelectric properties to the thermocouple electrode material. It is used to connect thermocouples and measuring instruments to ensure accurate transmission of temperature signals.
Function
Extend signal transmission distance:
Thermocouples are usually installed in high temperature or harsh environments, while measuring instruments (such as temperature controllers, data acquisition systems) may be located at a distant location. Compensation wires are used to connect the two to avoid signal attenuation.
Reduce costs:
Thermocouple electrode materials (such as platinum-rhodium, nickel-chromium) are expensive, while compensation wires use low-cost alloys, which can reduce material costs without reducing accuracy.
Increase flexibility:
Compensation wires are flexible and easy to wire and install.
Classification by thermocouple types:
The model of the extension wire corresponds to the type of thermocouple, and the common ones are:
K-type compensation wire: used for nickel-chromium-nickel-aluminum (K-type) thermocouple.
J-type compensation wire: used for iron-constantan (J-type) thermocouple.
T-type compensation wire: used for copper-constantan (T-type) thermocouple.
E-type compensation wire: used for nickel-chromium-constantan (E-type) thermocouple.
Classification by accuracy level
General level: suitable for general industrial scenarios, with lower accuracy.
Precision level: suitable for high-precision measurement scenarios, with smaller errors.
Classification by use environment:
General environment: PVC insulation layer, suitable for dry and normal temperature environment.
High temperature environment: glass fiber or polytetrafluoroethylene (PTFE) insulation layer, high temperature and corrosion resistance.
Explosion-proof environment: with metal shielding layer, suitable for flammable and explosive places.
