What is a Thermocouple?
A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created. The voltage can then be interpreted using thermocouple reference tables to calculate the temperature.
NiCr-NiSi /NiAl (Type K) thermocouple wire finds the widest use in all basemetal thermocouple, at temperature above 500 °C.
Type K thermocouple wire has strong resistance to oxidation than other base metal thermocouples. It has high EMF against Platinum 67, excellent temperature accuracy, sensitivity and stability, with a low cost. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in the following cases:
(1) Alternatively oxidizing and reducing atmosphere.
(2) Atmosphere with sulphur gases.
(3) Long time in vacuum.
(4) Low oxidizing atmosphere such as hydrogen and carbon monoxide atmosphere.
NiCr-NiAl thermocouple wire can be produced as per the chemical composition requirement of the customers.
Insulation material: PVC, PTFE, FB or as per the customer's requirement.
Application of thermocouple wire
1. Heating - Gas burners for ovens
2. Cooling - Freezers
3. Engine protection - Temperatures and surface temperatures
4. High temperature control - Iron casting
