Type K is the most common thermocouple conductor(≥500℃), it has a good resistance against oxidation and can be recommended for oxidizing and inert atmospheres.It can not be used in sulphurous and vacuum atmospheres directly at a high temperature,as this will have a significant impact on the EMF values. The composition of positive(KP) is Ni90Cr10, negative(KN) is Ni97Si3.
Nickel chrome wire is a kind of non-magnetic alloy of nickel and chromium, it is widely used in heating elements. The maximum operation temperature of the heating elements is related to the wire diameter, it is better to choose thicker wires, the corrosive atmospheres also have a considerable relationship with the maximum operation temperature. The surface temperature is about 100C higher than the inner normally, when the operation temperature exceeds the limit, the oxidation of heating elements itself is accelerated, the heat resistance will be reduced, which is easily deformed,collapsed and even appreas to be broken, thereby shortening the service life.
Type J thermocouple alloys is suitable for using in vacuum, oxidizing and reducing atmospheres or inert gas atmospheres. Because of high temperature oxidizing quickly for JP, the measuring temperature range is restricted. The composition of positive(JP) is Fe100, negative(JN) is Cu55Ni45.
Type T thermocouple conductor is suitable for temperature below 0℃ with an upper temperature limit of 350℃(ASTM E230:370℃) and can be used in oxidizing and reducing atmospheres or inert gas atmospheres,The composition of positive(TP) is Cu100,negative(TN) is Cu55Ni45.
Pure nickel wire has good mechanical strength, corrosion resistance and high heat resistance. It is suitable for making electrical vacuum devices, electronic instrument components, and corrosion resistant materials.

Copper nickel wire has good mechanical strength, corrosion resistance and low resistance. It is suitable to make thermal components in low-voltage electrical appliances such as thermal overload relays, low-voltage circuit breakers and household appliances. Copper nickel alloys are also the key materials for manufacturing geothermal cables.
Type E bare thermocouple wire develops the highest source voltage(EMF) per℃ for measuring tiny temperature shift,it is suitable in oxidizing or inert gas atmospheres up to 900℃(ASTM E230:870℃), The composition of positive(EP) is Ni90Cr10, negative(EN) is Cu55Ni45.
Type N thermocouple conductor is suitable in the similar atmospheres with type K and the operating temperature is -200-1300℃. Its advantage is thermoelectric stability. The composition of positive(NP) is approximately Ni84.4Cr14.2Si1.4, negative(NN) is Ni95.5Si4.4Mg0.1.
The mineral insulated RTD cable is combined with thinfilm element,Mgo powder insulated and sheath materials,as a compact entirety. Its principle is according to the resistance changes as the temperature changes.The MI RTD cables are the base material for RTD sensors, its structure advantage with anti pollution and mechanical strength promise can be applied in the harsh environment.
The RTD probe is composed of an element,sheath,lead wire and connector, it is working principle is the resistance of a metal changes with temperature.An electrical current is transmitted through the RTD element located in proximity to the area where temperature is to be measured, the resistance value is then measured by an instrument.
Mineral insulated copper cable(MICC) is combined annealed copper as conductor, Mgo powder as insulation, and annealed copper tube as sheath, it is widely applicated in the power industry.
We use mineral insulated cable to make mi cable probes and the probes can be assembly to different kinds of thermocouples. the specifications of thermocouple probe are from DIA0.25 to 12.7mm or 0.010 to 0.500 inch with SS,Inconel sheath,etc.

Mineral insulated copper cable(MICC) is combined annealed copper as conductor, Mgo powder as insulation, and annealed copper tube as sheath, it is widely applicated in the power industry.
SICC is the first pioneering companies to manufacture MIMS(Mineral insulated metal sheath) cable to improve product performance and reliability. Over the decades, we’ve refined and improved that technology,as it remains the heart of our products to this day. We specialise in: •Mineral insulated thermocouple cable • Mineral insulated RTD cable • Mineral insulated heating cable • Mineral insulated copper cable
Mineral insulated thermocouple cable is used to insulate thermocouple wires from one another and from the metal sheath that surrounds them. MIMS Cable has two (or four when duplex) thermocouple wires running down the middle of the tube. The tube is then filled with magnesium oxide powder and compacted to ensure the wires are properly insulated and separated. Mineral insulated cable helps to protect the thermocouple wire from corrosion and electrical interference.
