Compensating wire alloy wire for thermocouple
Time of issue : 2017-06-23 01:42:00
The function of the compensation wire for the thermocouple is to extend the cold electrode of the hot electrode, that is, the cold end of the moving thermocouple, and form a temperature measurement system by connecting with the display instrument. The use temperature is between -25 and 200 °C.

Nicrosil-Nisil thermocouple (Type N)
Time of issue : 2017-06-23 01:40:00
Nicrosil-Nisil thermocouple is the latest base metal thermocouple, developed to improve the drawbacks that type K thermocouple has. The main chemical composition of positive leg Nicrosil(NP) is Ni: Cr: Si≈84.4: 14.2: 1.4; negative leg Nisil (NN) is Ni: Si: Mg≈95.5: 4.4: 0.1. Type N thermocouple also be used in the similar atmospheres that type K works, and the operating temperature range is -200~1300℃。

Type N thermocouple improves the EMF drift and short term EMF change, compared to type K thermocouple, and has a longer life than type K thermocouple. Therefore, in the industries where temperature control and measurement are especially critical, type N thermocouple has more advantages than other thermocouple as it has long life and stable thermal EMF.

NiCr-NiSi thermocouple wire (Type K)
Time of issue : 2017-06-23 13:59:00
NiCr-NiSi (Type K) thermocouple finds the widest use in all basemetal thermocouple, at temperature above 500℃。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℃(for short term) and 0~1100℃( 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 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
