HI-3627 ELF Magnetic Field Meter
Frequency Range: 5 Hz – 200 Hz
The HI-3627’s remote sensor and meter make quick work of determining ELF magnetic field distributions in various applications such as power-line emissions, home ambient environments and high current factory locations. A data logger or chart recorder can be connected to the HI-3627 output to monitor field variations over time. The 2 kHz upper cut-off frequency enables accurate measurements of more than 30 harmonics of a 60Hz-power frequency field. The switch-selectable, lower frequency cut-off point enables testing to Swedish MPR and IEEE 1140 guidelines.
Signals from three orthogonal sensing elements are combined in a vector sum to provide accurate magnetic field measurements from any ELF magnetic field source. These include single- or polyphase electrical circuits, VDT’s, household wiring and appliances.
