| The strain gauge consists of a thin wire or narrow strip of a metallic conductor such as constantan, an alloy of nickel and copper. |
|
| Another alloy in this series, containing either 45 percent or 40 percent nickel, became widely known under the name constantan. |
|
| In the case of selected materials such as constantan this factor remains constant even when the conductor is undergoing plastic deformation. |
|
| The constantan was patterned using conventional photoresist. |
|
| Increasing copper to 55 percent produces the electrical resistance alloy known as constantan, which is used as a thermocouple in conjunction with pure copper. |
|
| While many types of resistive metal foils are available for the construction of flexible heaters, the most common types are cupronickel, constantan, Inconcl and aluminum. |
|
| The polarity of the two Type E thermocouples is critical so that the Constantan on both of the thermocouples are connected together. |
|
| Constantan is well known as a simple alloy commonly used in thermocouples with a moderate Seebeck coefficient at room temperature. |
