DC or AC Current Transducer Hall Effect Sensor to Measure Amps Review

Average Reviews:

(More customer reviews)I used one of these sensors to monitor current going from a battery into an AC inverter to a blender. I used a Labjack U10 data logger and launched the free software it came with called "LJSCOPE.exe" This is like an Oscilloscope and showed me the waveform for the current that was flowing to the AC inverter. (Which uses Pulse Width Modulation - so it was all over the place.)

The H-ACDC-70 allows you to easily measure current through a wire running from a solar panel, wind turbine, battery charger, fuel cell, pedal power generator, inverter, radio, blender, or paddle wheel. It has an output range compatible with most data loggers like the ones sold by LabJACK, National Instruments, Hobo, dataq, and more.The output range is shown on the graph in above image.As you can see this current sensor has a linear response.This current sensor will change its output approximately ~0.033V for every Amp of current it detects.When there is no current flowing through the sensor it puts out a default Voltage of 4.0V DC.If the wire you are monitoring has 10 amps flowing through it, then the current sensor will output about 4.330 volts DC.To increase sensitivity simply loop the sensed current path wire through the sensor as many times as needed to increase the gain to the desired level. Hookup for this Hall Effect current transducer sensor takes about 15 minutes.You will need to first secure the sensor using the four screw holes, and then hook up the green connector to your data logger or your hand held volt meter.Then you will need to pass your positive or negative power wire through the round donut shaped sensor. You must only put one of your wires through the sensor at a time because having two go through the sensor will cancel out the magnetic field and the sensor will not respond.The last step is to provide this sensor with 12v to 30V through the black connector that has a 2.5mm ID.This sensor comes with a 12V power supply that plugs into an AC110V Outlet.
