Abstract

Thermocouple junctions located in the hot and cold regions of an elongated heat conductive body extending through a measurement zone of a power monitoring device, are interconnected in series to provide a differential temperature signal of increased signal strength and fast signal response. The signal is free of the error heretofore arising from asymmetrical axial heat flow through the heat conductive body.
