The magnetic, handheld coil FESP 5132 was designed to generate defined magnetic fieldstrength in the audio frequency range up to 100 kHz. The main application is immunity testing against magnetic fields according to EN 55103 and MIL-STD-461 E. Depending on the current source characteristics magnetic fields up to 1500 A/m can be generated for a short time.

The generated magnetic fieldstrength is proportional to the coil current. A distance ring allows a precise spacing of 50 mm between coil and EUT surface. Other distance rings can be used to scale the current-fieldstrength ratio. The highest fieldstrength levels can be achieved using the shortest ring. There are further rings available on request in order to provide a certain scaling between coil current and magnetic fieldstrength (e.g. 1 Amp coil current = 100 Amp/m fieldstrength).

 

Application as magnetic field probe:

The FESP 5132 can also be used to measure existing magnetic fields. The open circuit output voltage is directly proportional to the magnetic fieldstrength (at fixed frequency) or directly proportional to frequency (at constant magnetic fieldstrength).
