Fluxgate Based, for Non-Intrusive, Isolated Current Measurement

HBM's CTS/CTM 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, such as those found in electric drives or other inverter-based power applications. The 1U rack-mountable interface unit can support any mix of up to six CTs.

Accurate

  • ppm class accuracy 
  • High bandwidth 
  • Flat bandpass behavior 
  • Superior dynamic response

Highest possible accuracy – for AC or DC signals 

Easy to Use

  • Industry standard 9 pin connector 
  • Small form factor power supply  
  • Large aperture size 
  • Wide operating temp range

Easy to Use – mounted in minutes

Reliable

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

Reliable operation – advanced EMC and overload protection

Shop Our Current Transducers:
