Description
LR8513 Wireless Clamp Logger for Current Monitoring
The Hioki LR8513 Wireless Clamp Logger is purpose-built for professionals who need a simple, safe, and flexible way to monitor electrical current in real-world environments. Designed as a wireless, two-channel AC and DC current input module, the LR8513 supports both load current and leakage current measurements when used with compatible clamp sensors.
This logger is particularly effective for maintenance and inspection tasks where installing traditional wired instruments is difficult or unsafe. By placing the LR8513 directly inside a distribution panel and closing the cover, users can monitor electrical values wirelessly from outside the panel, improving safety while reducing setup time.
Wireless Clamp Logger with Bluetooth Data Collection
Equipped with built-in Bluetooth technology, the LR8513 Wireless Clamp Logger allows measurement data to be collected on a smartphone, tablet, or computer while logging is ongoing. Data captured at different times is automatically merged into a single file, eliminating manual data handling and simplifying reporting.
Users can review trends directly in the field through waveform displays and numerical values, making it easier to identify abnormal load conditions, leakage increases, or peak demand periods. When combined with compatible Hioki display units, real-time waveform monitoring is also possible during active measurements.
Compact Clamp Logger for Panel and Equipment Installation
The compact, pocket-sized design of the LR8513 Wireless Clamp Logger allows it to fit easily inside switchboards, control panels, and confined electrical enclosures. Optional magnetic mounting accessories provide flexible installation on metal surfaces, eliminating the need for permanent mounting hardware.
Because data is transmitted wirelessly, there is no need to route signal cables through panel openings. This allows panels to remain closed during measurements, supporting safer operation and cleaner installations. The logger is also suitable for difficult-to-wire locations such as elevated equipment, moving machinery, and transportation systems.
Long-Term Load and Leakage Current Logging
Powered by two AA alkaline batteries, the LR8513 can operate for approximately 10 days at a one-second recording interval with Bluetooth enabled. A built-in power-saving function helps extend battery life by activating wireless communication only during scheduled periods. For extended monitoring, the logger can be powered using an AC adapter or an external 5 to 13.5 V power supply.
All measurement data is securely stored in the logger’s internal memory, which can hold up to 500,000 data points per channel, ensuring reliable data retention even when wireless communication is temporarily disabled.
