The Model 6221 is the only AC current source on the market. Until now, researchers and engineers have been forced to build their own AC current sources. The Model 6221 provides better accuracy, consistency, reliability, robustness, and cost effectiveness than "home-made" solutions. (read more)

ASM and AS Series current sensors operate as the sealed secondary of a current transformer while the conductor carrying the current to be measured functions as a one turn primary. (read more)

Current Sensing Relays provide an effective and highly stable method for monitoring electrical current. Current Transducers and Transmitters are for AC or DC Voltage & Current Voltage, Current, Power, Power Factor, Energy and Frequency can all be monitored in a single package. The sensed information is then provided to the system via an RS485 serial bus. (read more)

American Aerospace Controls (AAC), has released a new series of bi-directional current transducers capable of accurately following extremely fast (DC and/or AC) current waveforms. The 929 Series consumes a very low 80 to 270 mW during operation, and provides an ultra fast response to complex current waveforms in the range of DC to 350 KHz. (read more)

Hall effect, open-loop current sensors from Honeywell Sensing & Control. The CSCA-A Series of open-loop current sensors are based on the principles of the Hall-effect wherein a Hall-effect device (HED) produces an output voltage linearly related to the amplitude and phase of a magnetic field applied to it.
