CT9667 Series – AC Flexible Current Sensor

Hioki

Product Description

Hioki

CT9667-01 – AC Flexible Current Sensor , φ100 mm (3.94 in)
CT9667-02 – AC Flexible Current Sensor, φ180 mm (7.09 in)
CT9667-03 – AC Flexible Current Sensor, φ254 mm (10.00 in)

Note: These current sensors may also be used with Hioki power quality analyzers, power meters or Memory HiCorders. CT9667 is a flexible current sensor for measuring large currents. It is not suitable for measuring minute current such as leakage current.

Overview

Hioki current sensors are best-in-class devices for use with power meters, PQAs and Memory HiCorders. The CT9667 series are flexible Rogowski type AC sensors comprising of 3 different models in various loop diameter sizes from 100 mm to 254 mm. The 100 mm and 180 mm diameter sensor also feature extra thin cables for easier looping around complicated wiring. All 3 sensors 500 A/5000 A ranges, making them ideal for measuring large load current.

Key Features

  • Thinner cables are easy to use in confined spaces and with complicated wiring (-01, -02)
  • Shaped so that it’s easy to route through complex wiring
  • Easily supports large current measurements up to 5000 A
  • Wide 10 Hz to 20 kHz band with excellent frequency characteristics
  • Choose from three conductor diameter sizes
  • Combine with Hioki power meters or Memory HiCorders (with BNC input terminals)
  • CAT IV 600 V, CAT III 1000 V
