Overview
PEM CWT series Rogowski coil, and is currently a very advanced wideband, high-current Rogowski coil in the world. It features wide measurement bandwidth, a thin and lightweight form factor, and flexibility.

CWT wideband high-current Rogowski coils mainly include: CWT standard series, CWT LF low-frequency series, CWT mini series, CWT miniHF series, CWT Mini 50HF, CWT Ultra Mini, CWT LF, and other products.

Main performance specifications of the CWT standard model:


  • Peak current:  30A - 600kA peak 

  • Output:    ±6.0V (full scale); high-frequency bandwidth (-3dB): 16MHz

  • Accuracy (typical): up to ±0.2% at the coil center

  • Operating temperature range: 0°C to +40°C (integrator); –20°C to +100°C (coil + lead)

  • Coil length: 300, 500, 700, or 1000mm (custom lengths available)

  • Coil insulation: 10kV peak

  • Coil diameter: 8.5mm

  • Lead length: 2.5m or 4m (custom lengths available)

  • Power supply: AA battery or 12V DC power adapter


_______________________________________________________


Main features of the CWT standard model:

  • Traceable calibration data (including certificate)

  • Non-contact measurement has no effect on the circuit under test

  • No magnetic material means excellent linearity

  • Fully isolated from DC current, enabling measurement of small ripple currents on large DC currents

  •  Exceeding the current range will not cause damage(provided the absolute maximum di/dt is not exceeded)
