Fluxgate Based, for Non-Intrusive, Isolated Current Measurement

HBK's CTT series of current transducers feature industry-standard, fluxgate, closed-loop technology. The second harmonic zero flux detection ensures the highest accuracy and lowest drift. With the high-bandwidth support, they can be used with fast rise time signals with highest accuracy, such as those found in electric drives or other inverter-based power applications. This enables measuring with low measurement uncertainties at the highest bandwidth to detect even the smallest improvements.

Highest Accuracy for AC & DC Signals

  • Best in class for accuracy and stability
  • 2.000 kHz bandwidth (±3 dB)
  • Flat bandpass behavior 
  • Superior dynamic response

Easy to Use

  • Industry standard D-SUB 9 connector 
  • -40°C to +85°C operating range
  • Slotted mounting holes

Reliable

  • Full-aluminum body for superior EMI shielding
  • ASPC - advanced circuit for sensor protection
  • Large overload capacity
