FGM 03 Magnetic Field Sensor

Thursday, February 27, 2014, 6:15 PM

The FGM-X series of devices are very high sensitivity magnetic field sensors operating in the 50
microtesla range ( 0.5 oersted ). They are simple, essentially three terminal devices, operating from a
single +5 volt supply, the connections being ground, +5v and output. The output is a robust 5 volt
rectangular pulse whose period is directly proportional to the field strength, (giving a frequency which
varies inversely with the field), making it very easy to interface to a computer or micro controller. The
typical period swing for the full range of an FGM-3 is from 8.5 ms to 25 ms (~120 KHz to ~50KHz), a
clear indication of its high sensitivity.
