AC FLEXIBLE CURRENT SENSOR CT9667

Easy to Loop Around, Even in Confined Spaces

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 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.

Model No. (Order Code)

CT9667-01	φ100 mm (3.94 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.

CAT IV 600 V, CAT III 1000 V
