0.05mm to 10.0mm Alloy wire NiCr-NiSi K Type Thermocouple Bare Wire
Description:
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) .
Thermocouple bare wire is used at temperatures up to 1260°C
(2300°F). MICC thermocouple bare
wire is supplied with bright or oxidized surface according to
standard or special EMF requirements.
Each individual lead is calibrated against platinum and the EMF
values are shown on each coil or spool.
