Precision current probes SymmProFlexTM® type FCP xx21

The current probes FCP are designed for precision current monitoring, power, energy and electricity quality testing applications.

Properties

  • Quick and easy access to the measured current.
  • No additional error for wire position.
  • Symmetric flexible shielding for excellent suppression of strange electric fields.
  • Symmetric sensor coil for excellent suppression of strange magnetic fields.
  • Low noise, dual gain, high CMRR amplifier with precision integrator.
  • Low output impedance.
  • Super flexible sensor cable Ø 6 mm.
  • Application tailored sensor cable sensitivity and frequency range (optional).
