Clamp-on DC current meter

17 March 2010 Test & Measurement

Dynamp has released a new large-jaw, high-current clamp-on DC measuring device which is lightweight, battery powered and portable, suitable for spot checks in electrochemical and industrial plants.

The instrument can be used to measure the current distribution in parallel anode or cathode paths, as well as to verify power rectifier current. The sensor contains no iron and remains linear even when used in the large magnetic fields commonly found in electrochemical plants. It is designed to operate in corrosive chemical atmospheres, under wide temperature variations and high magnetic fields. It provides DC current measurement in dual ranges up to 100 kA and versions are also available to measure AC RMS current; accuracy is ±2,5%. The measurement head is available in a variety of sizes to enable its use with very large busbars.
