AC FLEXIBLE CURRENT SENSOR
CT9667
|
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. CAT IV 600 V, CAT III 1000 V Key Features |
Model No. (Order Code)
Note: These current sensors may also be used with HIOKI power quality analyzers, power meters or Memory HiCorders.  |
