The Cummins 3036575 Thermocouple is a specialized component designed for use in heavy-duty truck systems. Its primary role is to measure temperature accurately within the engine and exhaust systems, providing essential data for optimal performance and efficiency. This thermocouple is integral to maintaining the precise operational parameters required by modern heavy-duty engines.

Basic Concepts of Thermocouples

A thermocouple is a temperature-measuring device consisting of two different conductors that form junctions at two different temperatures. When these junctions are at different temperatures, a voltage is generated across the junctions. This voltage can be measured and converted into a temperature reading. The principle behind this is known as the thermoelectric effect, where a temperature gradient across the junctions of two dissimilar metals produces an electric voltage ¹.
