Based on advanced fluxgate technology, it ensures exceptional precision and stability while enabling accurate AC/DC current measurement up to 200 A. Its ultra-slim "Dolphin Clamp" design is optimized for tight spaces with dense wiring, such as inside vehicles, and allows for easy installation, even in confined areas like auxiliary battery current measurement. The clamp can accommodate conductors with a maximum diameter of 20 mm, making it versatile for a wide range of applications. Unlike many current sensors on the market, where the position of the conductor within the clamp can impact measurement accuracy, the CT6833 is designed for high reproducibility, regardless of conductor placement. Thanks to HIOKI’s precision engineering, measurement results remain stable and reliable, no matter where the conductor is positioned within the sensor. A major challenge in long-term current measurements is temperature-induced signal drift. While HIOKI fluxgate sensors already exhibit exceptionally low drift, this series pushes performance even further – reducing drift to a nearly unmeasurable level. Even in extreme conditions, such as under the bonnet of a vehicle, where temperatures can rise dramatically during testing, the CT6833 maintains stable accuracy within 0.01%, ensuring highly precise data acquisition for environmental testing and evaluation. To enhance usability and reliability in tight installations, the CT6833 also features an innovative locking mechanism that prevents accidental opening during measurement. In confined spaces, sensors are often pressed against surrounding components or squeezed between cables, which can put unintended pressure on the clamp. With its secure locking design, the CT6833 remains firmly closed, ensuring uninterrupted measurement reliability even in demanding conditions. With a wide frequency bandwidth of 50 kHz, the CT6833 can accurately capture dynamic current waveforms. This, combined with its exceptional accuracy, allows it to meet strict testing standards such as WLTP, ensuring highly reliable measurements in automotive and other precision testing applications. The CT6833 works directly with HIOKI Power Analyzers and Memory Recorders, which supply power to the sensor via the ME15W connector. When combined with a HIOKI sensor unit (CT9555, CT9556, or CT9557), it can also be used with oscilloscopes or other DAQ systems, providing a voltage output ratio of 4 mV/A. The total cable length of the CT6833 is 5 meters, ensuring flexibility in sensor placement. This includes 4 meters of cable between the sensor and its control box, plus an additional 1 meter from the control box to the connector, allowing for convenient integration into various test setups.
