The Data Logger Link adds Bluetooth Low Energy connectivity to a self-contained inertial recorder with microSD storage and a rechargeable battery. Wireless access to real-time and logged data makes it ideal for unmanned vehicle testing and motion measurement where a tethered connection is impractical.
Users can stream over BLE and record to microSD simultaneously, with USB-C available for wired data access and charging. Dual auto-selecting accelerometers provide low-range measurements and high-range sensing up to ±320g. Configurable time-based and event-based recording, an onboard real-time clock, and two battery capacities provide flexibility for different test requirements. Portable and integrated Screwdown/Strapdown cases are available.
