Toroidal current sensor M703AHSI

DCAC

AC/DC current and current pulse sensor Applicable for wire diameter 2.7 … 3.0 mm Supply voltages: 5 … 10.5 VDC (M703A); 9 … 20 VDC (M703B) The current and current pulse sensor Type M703A... is used for the measurement of DC and AC current as well as current pulses. The current pulse sensor is based upon the hall measuring principle and enables thus the indirect measuring of amperage in a wire. The benefits are: 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 produces 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.
