GMW Hall-effect current sensor CPCO-1000-160 open-loop clamp-on AC/DC probe 1000 A high-current 160 mm aperture

PROBEMART provides the GMW CPCO/CPC clamp-on (split-core) Hall-effect current sensor, which can measure DC to 50 kHz and 0–16000 A AC/DC current, with an overall measurement accuracy of 1%. It is mainly used for current testing of electric vehicles, motors, PV inverters, variable-frequency drives, battery charging/discharging, electromagnetic actuators, etc. It can usually be used with various power analyzers, recorders, data acquisition units, and oscilloscopes for testing.

Hall-effect current transformers measure the DC component based on the magnetic-balance Hall-effect principle and the AC component based on the magnetic induction principle: a current C is fed into the control current terminals of the Hall element, and a magnetic field with magnetic flux density B is applied in the normal direction of the Hall element plane; then, in the direction perpendicular to the current and the magnetic field (i.e., between the Hall output terminals), an electric potential VH is generated, called the Hall voltage, whose magnitude is proportional to the control current. Hall-effect current probes are particularly suitable for high-precision AC+DC measurement scenarios.
