DEWETRON offers several solutions for current measurement from simple shunts to current clamps and high-precision zero flux transducers. There are versions for pure AC current which do not need any power supply and versions for DC and AC current which can be supplied from the DEWETRON instrument. Have a look at the tables below.
You are looking for an RPM or angle sensor to complete your DAQ system for your demanding measurement task? Then have a look at our Tape Sensor below.

You need to connect more current transducers to a DEWE3-A4 or a DEWE3-M4? Then use the DW2-CLAMP-DC-POWER-8 box for connecting up to eight current clamps to a DEWE3-A4/DEWE3-M4/DEWE2 system.
The box comes with an integrated power supply for up to eight current clamps (±15 V / +9 V), as well as a power supply connector for the instrument (11 to 32 VDC).
