There are many types of thermocouples, Themocouples may also be connected in series to make a "thermopile"The most common thermocouple types are:Type K (chromel{90 percent nickel and 10 percent chromium}-alumel)(Alumel consisting of 95% nickel, 2% manganese, 2% aluminum and 1% silicon) is the most common general purpose thermocouple with a sensitivity of approximately 41 µV/°C, chromel positive relative to alumel.[7] One of the constituent metals, nickel, is magnetic; a characteristic of thermocouples made with magnetic material is that they undergo a step change in output when the magnetic material reaches its Curie point (around 354 °C for type K thermocouples).Type E (chromel-constantan)[5] has a high output (68 µV/°C) which makes it well suited to cryogenic use. Additionally, it is non-magnetic.Type J (iron-constantan) has a more restricted range than type K (−40 to +750 °C), but higher sensitivity of about 55 µV/°C.[2] The Curie point of the iron (770 °C)[8] causes an abrupt change in the characteristic, which determines the upper temperature limit.Type N (Nicrosil-Nisil) (Nickel-Chromium-Silicon/Nickel-Silicon) thermocouples are suitable for use at high temperatures, exceeding 1200 °C, due to their stability and ability to resist high temperature oxidation. Sensitivity is about 39 µV/°C at 900 °C, slightly lower than type K. Designed to be an improved type K, it is becoming more popular.
