Current measurement shunt circuit for accurate measurement of currents in the range of milliamps to kiloamps, whereby the shunt resistance is thermally coupled to the current measurement circuit to provide temperature compensation

摘要

Current measurement circuit with a shunt in which the measurement resistance (Rsh) is thermally coupled to the measurement current path (OP1). Accordingly the measurement resistance has a wire coiled around it along its longitudinal axis between its voltage taps, with the wire being of the same material as the resistance. One coil end is connected to a measurement resistance tap and the other end is connected to the current path. The other end of the measurement resistance is also connected to the current path.
