Induction Coil Sensors

Although they respond to dB/dt, the low frequency response can be extended down to 0.001 Hz or less. Thus these sensors can detect very slow changes in magnetic field. Using innovative electronics and modern techniques, we have developed one of the most sensitive induction coil sensor with internal noise of 10-8GHz-1/2. Sensitivity is maintained flat from 0.001 Hz to 1 KHz using a feedback system. The high frequency response is typically around 1 KHz, but composite system with frequencies from 0.001 Hz to hundreds of MHz can be delivered.

There are numerous applications of induction coil sensors- particularly when the change in field is measured. Most of the measurements use the field change for detections and surveillance.

Some of the striking applications include detection of extreme low frequency variations in e.m. field. Because of the wide bandwidth, the same sensor can be used for electromagnetic surveillance over a wide range of frequencies. Applications include most of the typical used of fluxgate magnetometers and additionally:
