Pearson current monitors are not a separate class of devices, and their design follows rules required for high-frequency current transformers. The name “Pearson” is a registered trademark of Pearson Electronics Inc. who began production of such devices in 1950s.4)

Nowadays the company specialises in precision, wide-band and high-frequency current sensors.5)

Typical applications

A common feature is that the device is equipped with BNC plug suitable for direct connection to an oscilloscope, through a 50 Ω coaxial cable.

The Pearson current monitors can be used over similar range of frequencies and currents as Rogowski coils (from single Hz to MHz), but they usually offer better sensitivity6), but the cores are rigid so cannot be used in applications were flexible Rogowski coils are required.

Typical applications include:
