Product Description

Type K Chromel / Alumel Thermocouple Bare Wire

 

Product Description

 

1. Thermocouple Wire Introduction: 
 

NiCr-NiSi (Type K) thermocouple finds the widest use in all basemetal thermocouple, at temperature above 500 °C.

The main chemical composition of positive leg
NiCr (KP) are Ni≈90% and Cr≈10%;
negative leg NiSi (KN) are Ni≈97% and Cr≈3%.

The operating temperature range is -200~1300°C(for short term) and 0~1100°C( for long term) .

Type K thermocouple 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 case:

    (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.

Specification

Type K Temperature Range:

    (1)Thermocouple grade wire, -200~1300ºC(for short term) and 0~1100ºC( for long term)

    (2)Extension wire, 32 to 392F (0 to 200C)

 

Type K Accuracy :

    Standard: +/- 1.5C or +/-0.4%t
