J type thermocouple product introduction

The application of J type thermocouple


J type thermocouple) Also known as the iron - Constantan thermocouple.


it's the positive ( 摩根大通(JP) In the name of the chemical composition of pure iron, the cathode ( 约) For copper and nickel alloy, has often been vaguely call constantan, its nominal chemical composition of: 55% copper and 45% nickel as well as small amounts of very important manganese, cobalt, iron and other elements, although it's called constantan, but differs from that of nickel and chromium - Constantan and copper - Constantan constantan, so can't use EN and TN to replace. Iron - Constantan thermocouple measuring temperature area for - 200 ~ 1200 ℃, but usually use temperature range of 0 ~ 750 ℃


J type thermocouple has advantages of good linearity, thermoelectric emfs is larger, higher sensitivity, stability and uniformity is good, widely used by users. J type thermocouple can be used in the vacuum, oxidation, reduction and inert atmosphere, but iron anode oxidation at high temperature quickly, so the temperature is restricted, cannot be directly without reserve for curing atmosphere at high temperature.
