AC FLEXIBLE CURRENT SENSOR
CT7040 series
|
Hioki clamp sensors are best-in-class measuring devices incorporating Hiokiâs expertise in current sensing technology. The CT7040 Series compromise of 600A/6000A AC flexible current sensors in three different loop sizes that pair with the detachable Display Unit to measure large currents in crowded wiring and confined spaces. CAT IV 600 V, CAT III 1000 V A comment of Good Design Award 2016 Key Features |

Note: CT7040 series cannot be used alone. Use with the Display Unit CM7290, CM7291 to connect with Data Loggers and Memory HiCorders. When used in combination with CM7290 or CM7291, the frequency band of current display and waveform output becomes narrow.   |
 |
Connect to Recorders, Data loggers, and Oscilloscopes Must be paired with the Display Unit CM7290 or CM7291 to operate as a standalone unit. Add an output cord to deliver signals to a data logger or Memory HiCorder for the following types of output: âĒ A DC or AC (up to 5 kHz/10 kHz) current waveform as-is (using WAVE mode for waveform output) |

Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
* It is waterproof to maintain measurement function, and measuring the live part in wet condition increases the risk of electric shock.
