    DynAmp LKP

    DynAmp LKP

    The LKP-30 is a high accuracy, “closed-loop” Hall effect system designed to accurately and reliably measure unidirectional dc bus currents up to 30 k amperes. This “system” consists of a two-piece measuring head, which installs around the bus, an electronics unit and two multiconductor cables connecting the two.


    Application

    The LKP-30 is particularly well suited to measure individual as well as total bus currents in Electro-chemical processes including aluminum, chlorine, copper, manganese, titanium, zinc as well as electroplating and coating processes.
