Description
CT7822 AC/DC Current Sensor for Precision Measurement in Tight Spaces
The CT7822 AC/DC Current Sensor is engineered for engineers, technicians, and researchers who need reliable current measurement without sacrificing installation flexibility. As one of the smallest current sensors in its class, it combines a compact form factor with professional-grade accuracy, making it suitable for advanced electrical testing and monitoring applications.
Compact Design for Confined Wiring
Modern electrical systems often feature dense wiring and limited access points. The CT7822 AC/DC Current Sensor addresses this challenge with a slim φ5 mm clamp diameter, allowing effortless installation even in confined spaces with complex conductor routing. Its compact size also enables multiple sensors to be mounted close together, supporting multi-channel measurements and detailed system evaluations.
High Accuracy with Non-Contact Safety
The CT7822 AC/DC Current Sensor delivers accurate measurement of AC and DC currents up to 20 A while maintaining a non-contact measurement method. This approach allows current to be measured without cutting or disconnecting conductors, improving safety and reducing installation time. The result is consistent, repeatable data that professionals can trust during diagnostics, validation, and performance analysis.
Performance Across Wide Temperature Ranges
Temperature fluctuations can affect current measurement accuracy, particularly at low current levels. The CT7822 AC/DC Current Sensor is designed to operate reliably from −40°C to 85°C, ensuring stable DC current measurement even in harsh or variable environments. This makes it suitable for automotive electronics, industrial systems, and environmental testing applications.
Monitoring and Data Logging Applications
Designed for compatibility with high-precision measuring instruments, the CT7822 AC/DC Current Sensor supports long-term monitoring and waveform analysis. Its combination of compact size, accurate performance, and environmental robustness makes it a dependable choice for research and development, system verification, and maintenance tasks.
