We use electromagnetic shielding parts that can stop outside signal interference, and we fit high-sensitivity sensing parts to catch tiny electric signals. We add low-noise amplifier chips to raise signal strength step by step, and we install filter circuits that clear useless signal noise. We also build in automatic zero adjustment and temperature correction tools which fix measurement errors caused by part changes.
The Rogowski coil sends out a faint difference signal that changes with the speed of current shift. People need an integrator board to boost this signal so users can read exact current values. This integrator uses quiet circuit parts and raises signal gain to a suitable level. This board has filter modules, zero adjustment tools and temperature correction parts that work with fine-tuned integration settings, and it strengthens useful signals while cutting outside noise and value shift.
