Ring coil for soft magnetic materials equipment

Ring coil for soft magnetic materials equipment

A ring coil consists basically of an open multipolar connector, in which its pins are connected to give NH excitation turns and NB measuring turns when closed. Ring coils are usually tailored to specific sizes, materials, frequencies, levels, since different measuring conditions require different NH and NB values. Most of the ring coils can be used in a wide range of measuring conditions. Each ring coil contains both primary and secondary windings. The primary winding carries the current to produce the excitation field H.

LE offers two ring coils for measurements at low frequency and high frequency.
