Printed Circuit Board Coils
The Rocoil® Printed Circuit Board (PCB) coils are made using printed circuit techniques with tracks and vias to create a toroidal coil. Once the artwork has been prepared these coils can be produced in large quantities. PCB coils can be provided in a wide range of sizes and are well-suited for bespoke designs. PCB coils can be stacked together and connected in series to increase the output.
Rocoil Printed Circuit Board Coils Features
With a suitable electronic integrator these coils can be used to measure currents with a resolution as low as a few mA and high currents of greater than 1MA. They provide complete isolation from the circuit being measured and have no effect on the current being measured even for very low-impedance circuits.
