A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature. Thermocouples are widely used as temperature sensors. [1] Commercial thermocouples are inexpensive, [2] interchangeable, are supplied with standard connectors, and can measure a wide range of ...
Thermocouples can be connected in series as thermocouple pairs with a junction located on either side of a thermal resistance layer. The output from the thermocouple pair will be a voltage directly proportional to the temperature difference across the thermal resistance layer and also to the heat flux through the thermal resistance layer.
Interchangeable parts are parts that are identical for practical purposes. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type.
Figure 2: [8] Working principle of a thermal laser sensor (Adapted from figure 3 with permission) As shown in Fig 2, a thermopile laser sensor consists of several thermocouples connected in series with one junction type (hot junction at temperature T 1) being exposed to an absorption area and the other junction type (cold junction at temperature T 2) being exposed to a heat sink.
Ford would often use interchangeable parts between car models to save costs, but slowly decreased after it lost market share to Chevrolet. The concept of interchangeability was crucial to the introduction of the assembly line at the beginning of the 20th century, and has become an important element of some modern manufacturing but is missing from other important industries.

Interchangeable parts, the ability to select components for assembly at random and fit them together within proper tolerances; Interchangeability (computer science), the ability that an object can be replaced by another object without affecting code using the object; Interchangeable random variables in mathematics
In thermocouples the Seebeck effect is used to measure temperatures, and for accuracy it is desirable to use materials with a Seebeck coefficient that is stable over time. Physically, the magnitude and sign of the Seebeck coefficient can be approximately understood as being given by the entropy per unit charge carried by electrical currents in ...
