Current clamps

Current clamps (AC current sensors) are used as scaling converters (current to voltage conversion) for contactless AC current measurements within the commercial frequency range.

DESCRIPTION:

Current clamps (AC current sensors) are used as scaling converters (current to voltage conversion) for contactless AC current measurements within the commercial frequency range.  

Each set of clamps is calibrated together with the particular instrument (each measurement channel is assigned to a certain clamp) to achieve higher accuracy.
You can complete your instrument of Energomonitor or Energotester family with the following AC current sensors:

  • Rated current 10A; sensing window 8 mm; high measurement accuracy
  • Rated current 10A; sensing window 16 mm
  • Rated current 100A; sensing window 20 mm
  • Rated current 1000A; sensing window 60 mm; typical or high measurement accuracy

Flexible current clamps ME FLEX 3003; rated current 30/300/3000A; sensing window 200 mm. The set of Flexible AC Current Sensors. ME FLEX 3003 is equipped with a 3-range measuring amplifier and Power Adapter for charging its internal batteries. The 3-range amplifier is powered from two AA Ni-Mh rechargeable batteries (1.25V) or from two AA alkaline batteries (non-rechargeable, 1.5V).
