ABSTRACT:
Several embodiments of a temperature gradient sensing probe formed from a printed circuit thermocouple array are disclosed. The printed circuit thermocouple array is formed by an electrically insulative sheet having a first surface, a second surface and N electrically conductive junctions passing through the sheet from the first surface to the second surface, wherein N is an integer greater than one. N electrically conductive paths formed from a first conductive material are applied to the first surface, wherein each of the N conductive paths formed from the first conductive material have a junction end electrically connected respectively to one of the N conductive junctions and a connector end for electrical connection to a signal transmission conduit. N electrically conductive paths formed from a second conductive material, dissimilar to the first electrically conductive material are also provided. The N conductive paths formed of the second material have a junction end electrically connected to one of the N conductive junctions and a connector end for electrical connection to a signal transmission conduit. The array may be applied to a shaft or disposed within a tube to form the probe. The N conductive paths formed of a second material may be replaced by a single, common conductive path formed of the second material which is connected to the conductive junctions. A panel connector for the probe is also disclosed.
