Thermocouples generate voltage through the Seebeck effect, a principle where a temperature difference between two dissimilar metals produces an electromotive force (EMF). This voltage is proportional to the temperature gradient, making thermocouples reliable for industrial and scientific temperature measurements. A thermocouple consists of two [...]

A thermocouple is a temperature-sensing device widely used in industrial and scientific applications. It consists of two dissimilar metal wires joined at one end to form a junction. When this junction experiences a temperature change, it generates a voltage that correlates to the temperature difference [...]

William Nash and Eric Yeager – Cleveland Electric Labs; Twinsburg, Ohio As a designer and manufacturer of thermocouples, the most commonly asked question we receive is: How long should my thermocouple last? Unfortunately, the answer to this question is quite complex and is dependent [...]

Thermocouples: Precision Temperature Sensors for Industrial Applications Thermocouples are vital instruments in industrial applications, providing precise temperature measurement through voltage potential. These sensors are made from two dissimilar metals, joined at electrical junctions. When exposed to varying temperatures, the junctions produce a voltage that [...]

Introduction to Platinum Thermocouples Platinum thermocouples are high-precision temperature sensors widely used in industrial applications for measuring extremely high temperatures. Constructed using platinum and platinum-rhodium alloys, these thermocouples are designed to provide accurate readings and stability over extended periods, making them ideal for environments [...]

Thermocouple History Thermocouples function based on the fundamental principle known as the Seebeck effect, discovered by Thomas Johann Seebeck in 1821. This effect elucidates the generation of an electromotive force (EMF) or voltage when two dissimilar metals are connected at two junctions, and there [...]

Thermocouples are reliable temperature measurement devices used in many industrial applications, but even the most durable components can fail over time. So, why do thermocouples go bad? Various factors such as mechanical damage, overheating, and contamination can contribute to their deterioration. Understanding the common causes [...]
