Patent abstract
The current measuring device comprises a first measuring resistor to receive a measurement current, and a first signal amplifier having an input connected to said first measuring resistor and an output to provide a first measurement signal. A second measuring resistor is connected in series with said first measuring resistor, and first voltage limiting means are connected in parallel on the first measuring resistor to branch a first shunt current off when a first limiting voltage is reached on said first measuring resistor. The value of the first measuring resistor is greater than the value of the second measuring resistor A processing unit comprises one such current measuring device.
