Frequency is the number of occurrences of a repeating event per unit of time.
It is also referred to as temporal frequency, which emphasizes the contrast to
spatial frequency and angular frequency. Frequency is measured in hertz which is
equal to one event per second.
The RVmagnetics MicroWire sensors measurements excited by the excitation coil and
gathered by the sensing coil.
The frequencies respectively are, frequency of exciting coil – from DC up to
20 kHz (audio freq.) frequency of sensing coil – up to 10.000 times
