· The temperature range of these types of thermocouples is from 32 till 1400 degrees Fahrenheit. The color for these thermocouples is either red or white. Type K : The type K thermocouple is having chromel as their positive leg and an alumel as their negative leg. Alumel is having 5 percent nickel and rest is silicon and aluminum. These types of thermocouples are suggested to be used in the environment of inert or oxidation. These thermocouples are having temperature ranges …
T Type Thermocouple (Copper/Constantan): These T type are very stable. These are made up with copper material and are used for very low temperature applications such as ultra low freezer or cryogenics etc. Its temperature range is in between -454 to 1600F. and accuracy level is +/- or +/- %, shown in figure 4.

· Different Thermocouple Types & Ranges. Thermocouples are classified into different types namely Type-K, Type-J, Type-T, Type-E, Type-N, Type-S, Type-R, and Type-B. These types of thermocouples have their own characteristics. But, a thermocouple is surrounded by a safety sheath for separating it from the environment. This safety sheath will reduce the corrosion effect drastically.
Thermocouples Thermocouple Types- Type J Thermocouple, Type K Thermocouple, Type E Thermocouple, Type T Thermocouple, Type N Thermocouple, Type B Thermocouple, Type R Thermocouple, Type S Thermocouple. Manufactured to …

· Thermocouples and its types. 1. M&M SELF STUDY SUBMITTED BY RV COLLEGE OF ENINEERING. 2. Thermocouple Temperature Limit. 3. 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.
· Thermocouple Types and Thermocouple Range. There are four different classifications of thermocouple pairings, most distinguished by a capital letter heading. These are the home body class, the upper crust class, the rarified class and the exotic class. The home body class consists of “standard” or commonly used metals, while the upper crust class represents all platinum …
The Type K thermocouple is composed of a Nickel-10% chromium (+) wire versus a nickel-5% aluminum and silicon (-) wire. This type of thermocouple should only be used in oxidizing or inert atmospheres with a service temperature range between -200°C and 1260°C (-330°F to 2300°F).
There are several common types of thermocouple available, each with a characteristic sensitivity and optimal temperature measurement range. The following graph shows the thermocouple voltage produced by each as a function of temperature (assuming a cold junction at 0 °C).
The thermocouple types can be subdivided in 2 groups, base metal and rare (noble) metal: -200°C up to 1200°C – These thermocouples use base metals Type K – Chromel-Alumel: The best known and dominant thermocouple belonging to the group chromium-nickel aluminium is type K. Its temperature range is extended (-200 up to 1100°C). Its /
Type J, K, T, & E are “Base Metal” thermocouples, the most common types of R, S, and B thermocouples are “Noble Metal” thermocouples, which are used in high temperature applications (see thermocouple temperature ranges for details). Thermocouples are used in many industrial, scientific, and OEM applications.
There are many types of thermocouples, each with its own unique characteristics in terms of temperature range, durability, vibration resistance, chemical resistance, and application compatibility. Type J, K, T, & E are “Base Metal” thermocouples, the most common types of thermocouples. Type R, S, and B thermocouples are “Noble Metal” thermocouples, which are used in high temperature ...
· Types of Thermocouples and Their Applications. Some thermocouple applications include measuring steel during machining. B, K, R, and S type thermocouples are most suited to this job because of their high temperature ranges. This helps the manufacture know when the molten material is melted to a sufficient temperature.
The K type thermocouple is the best-known sensor within thermocouple-type temperature sensors, surely because the literature has falsely described it as a low-cost thermocouple with a wide range of temperature measurement. K type Thermocouple. A K type thermocouple …

Figure 4: A chart depicting some common thermocouple type ranges And those are just a few of the many different thermocouple types employed in all sorts of processes. Keep in mind, the temperatures and ranges we list are just a rough guideline; the accuracy of a thermocouple can be better within a certain sub-section of its range in comparison to its whole temperature envelope.
A Type E thermocouple offers better accuracy and signal quality compared to type K, and a good range of temperature measurement as well. Using nickel-chromium and constantan as its materials, this sensor ranges from -270 to 870 degrees Celsius, and the extension cable from 0 to 200 degrees Celsius. Although it has a similar SLE to the other three, it sports an accuracy of +- percent. Type N ...
· Types R and S have temperature ranges of 1000 to 2700 F and Type B thermocouples have a temperature range of 32 to 3100 F. As can be seen above, the difference between these three thermocouples is the amount of Rhodium contained in the negative leg. Types R and S can exhibit excessive grain growth in the platinum when exposed to the higher end of its temperature range. The …

Thermocouples are available in different combinations of metals, usually referred to by a letter, J, K etc giving rise to the terms type J thermocouple, type K thermocouple etc. Each combination has a different temperature range and is therefore more suited to certain applications than others. Although it is worth noting that the maximum temperature varies with the diameter of the wire ...
