MFC140
MFC140
∅7 flexible Rogowski coil

Highlights
  • Four available models: for indoor or outdoor use, with or without integrator
  • Suitable to measure currents from A to several kA
  • High linearity
  • Very useful with large size or awkward shaped conductors or in places with limited access
  • Not damaged by overloads
  • Non-intrusive, no power drawn from the main
  • Thanks to its light weight, it can be changed on the measured conductor
  • Totally shielded
Applications
  • Measuring devices, lab instrumentation
  • Power monitoring & control systems
  • DC ripple measurement
  • Harmonics and transients monitoring
  • Very high current monitoring
