Cu-CuNi thermocouple (type T) is also named Cu- Constantan thermocouple. The positive leg Cu(TP) is made by pure Copper, and the main chemical composition of negative leg Constantan (TN) is Cu: Ni≈ 55%: 45%. Although EN, TN, JN are all called Constantan, TN and EN don not give the same EMF output curve as JN. EN and TN are able to interchange but they are not interchangeable with JN. The operating temperature range of type T thermocouple is -200~350℃, Due to the low resistance of oxidation that Copper has, it is not advisable to go beyond that range.

Nicrsi-NisiMg (Type N) thermocouple is the latest base metal thermocouple, developed to improve the drawbacks that type K thermocouple has. The main chemical composition of positive leg Nicrsi (NP) is Ni: Cr: Si≈84.4: 14.2: 1.4; negative leg NisiMg (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℃.

NiCr-NiSi (Type K) thermocouple finds the widest use in all base metal 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)

NiCr- CuNi thermocouple (type E) is also named NiCr- Constantan thermocouple. The main chemical composition of positive leg NiCr (EP) is Ni: Cr≈90:10; negative leg Constantan (EN) is Cu: Ni≈ 55%: 45%. Although EN, TN, JN are all called Constantan, EN and TN don not give the same EMF output curve as JN. EN and TN are able to interchange but they are not interchangeable with JN. The operating temperature range of type E thermocouple is -200~900℃.

hermocouple compensating wire is used to connect the electrode (cold side of thermocouple) with display instrument in order to form a temperature measurement system. The working temperature is -25~200℃. Our plant mainly manufacture type KX,NX,EX,JX,NC,TX,SC/RC,KCA,KCB and WREC compensating wire for thermocouple, and they are used in temperature measurement instruments and cables. Our thermocouple compensating products are all made abiding by GB/T 4990-2010 ‘Alloy wires of extension and compensating cables for thermocouples’ (Chinese National Standard), and also IEC584-3 ‘Thermocouple part 3-compensating wire’ (International standard).

PTC Alloy wire has medium resistivity and high positive temperature coefficient of resistance. It is widely used in various heaters. It can automatically control temperature and adjust power by keeping constant current and limiting current. PTC alloy has many advantages such as automatic temperature control, automatic power regulation, constant current, current limiting, energy saving and long practical life.

CX400 is a nickel-copper, solid-solution alloy that offers good strength and toughness over a wide temperature range, including sub-zero temperatures. It provides excellent corrosion resistance and is also resistant to stress corrosion cracking and pitting in most industrial and fresh waters. As a result it is widely used in marine and chemical industries.

CX600is a nickel-chromium-iron alloy that provides superior resistance to oxidation at temperatures up to 1000 °C. It also provides good resistance against stress corrosion cracking in chloride environments. This alloy also offers good mechanical properties and workability. Owing to its good corrosion resistance properties at high temperatures, it is widely used in chemical and heat treatment industries. Since it maintains good mechanical properties at high temperatures, it is also used in the aeronautical industry to manufacture various aircraft and engine components.

The enamelled resistance wires are coated with a dual coat modified polyester enamel system which combines the excellent physical and electrical properties of a modified polyester base coat with the added chemical resistance, surface toughness, smoothness and high thermal rating of a polyamide-imide polymer topcoat. The combination of these two high quality resins produces a coating that has outstanding abrasion resistance, flexibility, chemical resistance, burnout and thermal shock resistance and dielectric strength. These properties, coupled with careful selection and processing of the resistance wire, produces an enamelled wire which meets the exacting requirements of the automotive and electrofusion industry.
