These differ from proximity and inductive displacement sensors in that they use an air-core coil instead of a ferromagnetic core. This eliminates the magnetic losses and thermal nonlinearities ...

Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it can reject PWM slew rates of >500V/µs and settles within 500ns to provide a 0.3% accurate (of full-scale) ...

ACS37030 and ACS37032 employ dual signal paths, with one capturing low-frequency and dc current using Hall-effect elements, and the other using an inductive coil to capture high-frequency data. The ...
