Direct current measuring device for voltage trigger`s electronic converter card, has processing unit with selection unit providing output signal, which depends on measured signals of sensors, for weak and strong electric currents
Direct current measuring device for voltage trigger`s electronic converter card, has processing unit with selection unit providing output signal, which depends on measured signals of sensors, for weak and strong electric currents
The device has magnetic sensors (4A, 4B) e.g. Hall Effect sensor, sensitive to a magnetic current generated by an electric current in an electric conductor (3), and a processing unit (7) connected to the sensors. The processing unit generates an output signal (S) depending on measured signals (SA, SB) provided by the sensors and representing the electric current. The processing unit has two inputs (11, 12) receiving measured signals of the sensors and a selection unit (13) providing an output signal, which depends on the measured signals, for weak and strong electric currents.
