Types of Thermocouple HeaterBelow are some types of thermocouples that are widely used according to international standards.1. Type KMade of Ni-Cr(+) and Ni-Al(-). Often used for combustion chambers such as boilers, reformers, high temperature steam etc. The cable is yellow for positive and red for negative with a range of -260 degC to 1200 degC.2. Type EMade of Chromel material (Chromel / Constantan (Cu-Ni alloy). Usually used for low temperatures with an output (68 V/°C). It has another type, namely non-magnetic.3. Type NMade of Nicrosil (Ni-Cr-Si alloy) / Nisil (Ni-Si alloy). It has the advantages of stability and high resistance to oxidation, making it suitable for measuring high temperatures without platinum.
Capable of measuring temperatures above 1200°C. the sensitivity is about V/°C at 900 °C, slightly below type K.4. Type JThis type is arguably less popular than type K. Its range is limited to the range of -40 to 750°C.5. Type TThis type is suitable for temperatures between -200 to 350°C. The material used for the positive conductor is copper while the negative is constant.
Often used for copper wire research. The sensitivity is ~43 V/°C.
