- Open Loop which has a voltage output in proportion to input current. Example +/- 5.0 volts for 500 Amp Scale
- Closed Loop which has a Current Output proportional to Input Current. Example +/- 50 ma for 500 Amp Scale. Now you might be able to find a +/- 20 ma transducer, but WTF would you do with 4 ma low signal. That is not capable of measuring ZERO Amps or of reversing polarity for current direction. Understand?
Hint find a Closed Loop Transducer with say a +/- 2.0 or 5.0 volt output for 200 to 500 Amp Full Scale reading. All you need to read the current is a volt meter.
Example a 2.0 volt / 200 Amp Model:
0 volts = 0 Amps
2.0 volts = 200 amps
