The current pulse sensor is based upon the Hall measuring principle and enables the indirect measuring of amperage in a wire. The measuring signal is galvanically isolated from the live wire, its current should be measured. Furthermore it is not necessary to split the live wire. Variations in the live wire produce a variation in the magnetic field around the wire. A hall sensor with toroidal core detects the variations of the magnetic field and delivers an output voltage, which is proportional to the current. The quality of the supply voltage linearily flows into the sensitivity and therefore into the measuring range.
