Description
Hioki CT7631 Current Sensor for Precise Low-Current Measurement
The Hioki CT7631 AC/DC Current Sensor is engineered for professionals who require accurate measurement and waveform capture of low-current electrical signals. With a measurement range of up to 100 A AC/DC, the CT7631 is well suited for testing control circuits, monitoring equipment performance, and analyzing current behavior in laboratory and field environments.
Flexible Display Integration
The CT7631 operates in combination with the Display Unit CM7290 or CM7291, allowing users to view real-time measurements and waveforms directly at the test site. This detachable display design supports efficient troubleshooting during inspections while also enabling easy connection to Hioki Memory HiCorders, data loggers, and oscilloscopes for extended analysis. Users can select from four output formats including waveform output, RMS conversion, peak detection, and frequency output, ensuring compatibility with a wide range of measurement workflows.
Stable Performance
Built for reliable operation, the CT7631 performs consistently across a broad temperature range from -25°C to 65°C. Its compact 33 mm core diameter makes it easy to clamp around insulated conductors in confined spaces, such as control panels and laboratory setups. The sensor is optimized for temperature-controlled environments where precise waveform observation is required, while still remaining suitable for on-site inspections.
Wireless Monitoring Capability
When paired with the CM7291 Display Unit, the CT7631 supports Bluetooth wireless communication. Measurement data and waveforms can be transmitted to a smartphone or tablet using the GENNECT Cross app, allowing users to review data in real time, capture screenshots, and simplify reporting. This wireless functionality improves efficiency during inspections and reduces the need for manual data handling.
Applications
The CT7631 is ideal for laboratory testing, electrical diagnostics, control system evaluation, and preventive maintenance. Its ability to mix and match with other CT7600 series sensors makes it a cost-effective solution for users who need coverage across multiple current ranges while maintaining consistent performance and safety.
