AC FLEXIBLE CURRENT SENSOR CT7040 series

Flexible 600A/6000A AC Current Sensors in 3 Sizes
Exclusive Academic Offer

Hioki clamp sensors are best-in-class measuring devices incorporating
Hioki’s 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.

GOOD DESIGNCE

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.

CAT IV 600 V, CAT III 1000 V
Key Features

• Ideal for use in environmental testing with broad -40˚C to 85˚C temperature range
• High precision with a clamp-type design, ±0.3% amplitude accuracy, ±0.1° phase accuracy
• Wide-bandwidth from DC to 20 kHz
• Single-handed operation and robust locking mechanism
• Reduced effects from magnetic fields, conductor position, and noise from nearby wires
• For EV/HEV battery charge and discharge efficiency testing and inverter and power conditioner conversion efficiency evaluations

A comment from the Good Design Award 2016

“I was impressed with the high level of functionality combined with a compact design and a dustproof and waterproof enclosure as well as the high level of technical skill evident in the integration of multiple types of plastic and two cables. These appealing products also exhibit beautiful finish quality.”


Connect to Recorders, Data loggers, and Oscilloscopes

The CT7000 series cannot be used alone. Use with the Display Unit CM7290, CM7291 to connect with Data Loggers and Memory HiCorders.

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.
