EM-6873 | 20 Hz – 100 KHz
The EM-6873 Loop Sensor Antenna uses passive circuits to transform magnetic field components between 20 Hz – 100 kHz to an equivalent open circuit two-terminal voltage on the receiving instrument. Use of the conversion Factor Chart, supplied with each antenna, will yield the strength of the magnetic induction field referenced to a uniform field. The loop is electrostatically shielded and therefore is sensitive only to the magnetic component (B-field) of the electromagnetic fields.
