NoordSolar Posted November 22, 2020 Share Posted November 22, 2020 I looking for a 100 A DC current sensor - so I can monitor the current balnce between two battery banks on a common busbar. It must not break into existing wiring - so a Hall effect clamp than can be permanently fitted . Cannot find anything? Quote Link to comment Share on other sites More sharing options...
Richard Mackay Posted November 22, 2020 Share Posted November 22, 2020 I've only come across Hall effect current measurement in expensive dc ammeters. Is there any reason why you can't use a 100A 75mV shunt? Quote Link to comment Share on other sites More sharing options...
NoordSolar Posted November 22, 2020 Author Share Posted November 22, 2020 I find it bizzaire that is required , you can get decent clamp DC mutimeters for under R1000 which measure 600A with good precision. The sensor itself cannot be more than R150 itself . Quote Link to comment Share on other sites More sharing options...
Stanley Posted November 23, 2020 Share Posted November 23, 2020 LEM makes a very large range of hall-effect sensors with different measuring ranges and supply voltages etc. https://www.lem.com/en R.S Components does stock quite a few of their products (for some reason they put them in the same category as the current transformers). Here is a link to one of them as an example: https://za.rs-online.com/web/p/current-transformers/0497182/ NoordSolar 1 Quote Link to comment Share on other sites More sharing options...
NoordSolar Posted November 23, 2020 Author Share Posted November 23, 2020 Thansk , they have quite a range too . Quote Link to comment Share on other sites More sharing options...
