Description
Hioki AC Flexible current sensor 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 to 254 mm. The 100mm and 180mm diameter sensor also feature extra thin cables for easier looping around complicated wiring. All 3 sensors 500A/5000A ranges, making them ideal for measuring large load current.
| CT9667-01 | φ100 mm (0.30 in) |
|---|---|
| CT9667-02 | φ180 mm (7.09 in) |
| CT9667-03 | φ254 mm (10.00 in) |
Note: These current sensors may also be used with HIOKI power quality analyzers, power meters or Memory HiCorders.
