Product Description
Tankii K type thermocouple wire 0.711mm 0.913mm
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.
Chromel alumel thermocouple wire can be produced as per the chemical composition requirement of the customers.
Thermocouple sensor's Application for different industries:
Heating - Gas burners for ovens
Cooling - Freezers
Engine protection - Temperatures and surface temperatures
High temperature control - Iron casting
