Hioki CT6873 Sensor for High-Precision Current Measurement
The Hioki CT6873 Sensor is a state-of-the-art AC/DC current sensor engineered to provide highly accurate measurements for research, industrial evaluation, and energy applications. Rated for currents up to 200 A and featuring a frequency bandwidth of DC to 10 MHz, it supports high-frequency and low-power factor current measurements with exceptional precision. This makes it ideal for evaluating inverter efficiency, EV quick charging, hybrid motors, PV power systems, and fuel cell battery testing.
Advanced Flux Gate Detection for Superior Accuracy
Hioki’s flux gate detection technology enables the CT6873 to measure both DC and low-frequency currents with minimal offset and excellent temperature stability. High-frequency currents are detected through the winding CT method, ensuring linearity and accuracy across a wide measurement range. This dual-detection method is crucial for inverter output power evaluation, transformer/reaction loss measurement, and long-term DC analysis.
Wideband Measurement and Phase Correction
With its DC–10 MHz bandwidth, the CT6873 excels in capturing fast-changing waveforms and high-frequency signals. Paired with the Hioki PW8001 Power Analyzer, the sensor automatically applies phase correction to ensure precise power calculations even under low-power factor conditions. This eliminates errors and maximizes measurement reliability.
Smart Automatic Sensor Detection
The CT6873 comes with built-in memory (I2C-EEPROM) that stores phase correction data, rated current, model, and serial number. When connected to the PW8001, all necessary settings are automatically detected, simplifying setup and preventing manual entry errors. This makes high-accuracy power measurement effortless and dependable.
Applications Across Industries
The Hioki CT6873 is suited for a wide range of applications: EV charging facilities, industrial inverter motors, PV power conditioners, wireless charging systems, and laboratory research. Its wide operating temperature range (-40°C to 85°C) ensures reliable performance in both automotive and industrial environments.
With the Hioki CT6873 Sensor, engineers and researchers can achieve accurate, reliable, and high-speed current measurements across DC and AC systems, enhancing productivity and precision in testing, evaluation, and monitoring processes.
