Overview
Hall effect current sensors measure AC and DC current without electrical contact, giving an isolated voltage or current output for data acquisition, inverters, battery systems, electroplating and power monitoring. Unlike a current transformer, a Hall sensor responds to DC as well as AC.
MEWOI's DS series spans a very wide range: small open-loop sensors for 10–40A through 5mm apertures, up to large closed-loop sensors for 20kA busbars and open-loop units rated to 80kA with a 120mm window. Open-loop sensors are simpler and lower cost; closed-loop sensors give better accuracy and linearity. Outputs include voltage, 4–20mA and 0–20mA depending on model, powered from ±12V to ±15V or +5V.
The table shows representative models; tell us your current range, AC/DC requirement, conductor size and output signal, and we will match the sensor.
