Understanding Type E Thermocouples
Type E thermocouples are highly regarded for their exceptional accuracy and stability, making them a popular choice in industries that demand precise temperature measurement. Comprising Chromel (nickel-chromium alloy) and Constantan (copper-nickel alloy), E Type thermocouples offer a wide temperature range (-200°C to 900°C) and excellent sensitivity. The positive leg (Chromel) and negative leg (Constantan) generate a voltage output proportional to the temperature disparity between the measurement point and the reference junction.
Functionality of Type E Thermocouples
Type E thermocouples produce a millivolt signal when subjected to a temperature gradient, based on the Seebeck effect. This effect generates a voltage due to the temperature difference between the two junctions, which is then converted into precise temperature readings by a connected instrument or controller, enabling accurate monitoring and control of industrial processes.
