HI-3627 Low Frequency Meter
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.
Key Features
0.2 mG - 20 G
5 - 200Hz
Three concentric orthogonal field sensors
True RMS Detection
Description
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 2kHz upper cutoff frequency enables accurate measurements of more than 30 harmonics of a 60Hz-power frequency field. The switch-selectable, lower frequency cutoff point enables testing to Swedish MPR and IEEE 1140 guidelines.
