AC Current Sensor
RCTi and RCTi 3ph
-
The RCTi & RCTrms sensors convert ac current to an isolated 0-5V voltage or 4-20mA current loop. TA5V-5A allows compatibility with existing 1A or 5A CT metering circuits. Both offer a choice of proportional (rms) and instantaneous outputs. The available RCT current ranges are 0-100A to 0-50,000Apk. Both RCTi and RCTrms provide accurate measurement over a wide bandwidth ensuring precise measurement even with harmonically distorted wave shapes - using a flexible clip-on sensing coil. The RCTs are available as single and three phase models.

SparkFun Current Sensor Breakout
ACS723 (Low Current)
-
The low current version of the SparkFun Current Sensor Breakout is a high accuracy board that utilizes the ACS723 for low to moderate AC and DC current sensing applications. The ACS723 sensor uses a Hall effect sensor to output a voltage relative to the current flowing through the IP+ and IP- pins on the board. The advantage of using a Hall effect sensor, specifically, is that the circuit being sensed and the circuit reading the sensor are electrically isolated meaning that, although your Arduino is running on 5V, the sensed circuit can be operating at higher DC or AC voltages!

Eddy Current Sensor
eddyNCDT 3001
-
The eddyNCDT 3001 is a new, efficient eddy current sensor whose compact dimensions have to date only been reserved for inductive sensors and proximity sensors. The temperature-compensated design provides high stability even in fluctuating ambient temperatures. The eddyNCDT 3001 comes with integrated electronics, offering an outstanding price/performance ratio and easy operation. The eddyNCDT 3001 eddy current sensor is ideally suited to OEM integration and machine building applications. The sensor is factory-calibrated for ferromagnetic and non-ferromagnetic materials, which eliminates the need for field calibration of the sensor. The eddyNCDT 3001 is available with connector or with integrated cable. A robust design combined with the eddy current measuring principle enables measurements in harsh industrial environments (oil, pressure, dirt). In addition, the eddyNCDT 3001 is suitable for offshore/marine applications (salt water).
