Thermocouple Bare Wire

IEC854-1 Type K thermocouple bare wire for Thermocouples Sensor Type K Thermocouple Wire Type K thermocouples usually work in most applications as they are nickel based and exhibit good corrosion resistance. It is the most common sensor calibration type providing the widest operating temperature range. Due to its reliability and accuracy the Type K thermocouple is used extensively at temperatures up to 2300°F (1260°C). This type of thermocouple should be protected with a

Thermocouple Wire Type S Thermocouple (Platinum Rhodium - 10% / Platinum): The Type S is used in very high temperature applications. It is commonly found in the BioTech and Pharmaceutical industries. It is sometimes used in lower temperature applications because of its high accuracy and stability. The type S is often used with a ceramic protection tube. Type R, S, and B thermocouples are "Noble Metal" thermocouples, which are used in high temperature applications. Type S

Thermocouple Wire Type R Thermocouple (Platinum Rhodium -13% / Platinum): The Type R is used in very high temperature applications. It has a higher percentage of Rhodium than the Type S, which makes it more expensive. The Type R is very similar to the Type S in terms of performance. It is sometimes used in lower temperature applications because of its high accuracy and stability. Type R has a slightly higher output and improved stability over the type S. Type R, S, and B

Thermocouple Wire Type B Thermocouple (Platinum Rhodium – 30% / Platinum Rhodium – 6%) The Type B thermocouple is used in extremely high temperature applications. It has the highest temperature limit of all of the thermocouples listed above. It maintains a high level of accuracy and stability at very high temperatures. The type B has a lower output than the other noble metals (type R & type S) at temperatures below 1,112F (600C). Type R, S, and B thermocouples are "Noble

Thermocouple Wire The Type T is a very stable thermocouple and is often used in extremely low temperature applications such as cryogenics or ultra low freezers. It is found in other laboratory environments as well. The type T has excellent repeatability between –380F to 392F (–200C to 200C).. The Type T thermocouple wire is composed of a copper (+) wire versus a nickel-45% copper (-) wire. The Type of thermocouple wire is frequently referred to as copper-constantan. This type

Thermocouple Wire NiCr- CuNi thermocouple wire (type E) is also named NiCr-Constantan thermocouple wire. It has a stronger signal & higher accuracy than the Type K or Type J at moderate temperature ranges of 1,000F and lower. The type E is also more stable than the type K, which adds to its accuracy. Type E thermocouple has the largest EMF output and highest sensitivity, so it is ideal for measuring small temperature change. It also has good stability in the low temperature

Thermocouple Wire Fe- CuNi thermocouple (type J) is also named Iron-Constantan thermocouple.. It is used in vacuum, oxidizing, inert or reducing atmospheres. Iron element oxidizes rapidly at temperatures exceeding 538'C, and therefore heavier gauge wire is recommended for longer life at these temperatures. Type J thermocouple has good resistance to oxidation and high EMF output against Platinum 67, with good temperature accuracy, sensitivity and stability. It is recommended

Thermocouple Wire Type N Thermocouple (Nickel-Chromium-silicon / Nickel-Silicon-Magnesium): The Type N thermocouple is composed of a nickel-14% chromium-1 1/2% silicon (+) wire versus a nickel 4 1/2% silicon-1/10% magnesium (-) wire. The Type N thermocouple is the newest addition to the ISA family. It was developed to be used under the same conditions as a Type K. Type N should be used in oxidizing or inert atmospheres with a service temperature range between -200°C and 1260

Thermocouple Wire Type N Thermocouple (Nicrosil / Nisil): The Type N shares the same accuracy and temperature limits as the Type K. The type N is slightly more expensive. The type N has better repeatability between 572F to 932F (300C to 500C) compared to the type K. Type N Temperature Range: Maximum continuous operating temperature: up to 2,300F (1,260C) Short term use: 2,336F (1,280C) Thermocouple grade wire, -454 to 2300F (-270 to 1,260C) Extension wire, 32 to 392F (0 to

Thermocouple Wire Type K Thermocouple (Nickel-Chromium / Nickel-Alumel): The type K is the most common type of thermocouple. It’s inexpensive, accurate, reliable, and has a wide temperature range. The type K is commonly found in nuclear applications because of its relative radiation hardness. Maximum continuous temperature is around 1,100C.
