The Data Logger Link combines inertial recording, microSD storage, and rechargeable battery power with Bluetooth Low Energy connectivity. Wireless access to live and recorded data makes it ideal for field and vehicle testing where a wired connection is impractical.
BLE streaming and microSD recording can run simultaneously, with USB-C providing wired access and charging. Dual auto-selecting accelerometers measure low-range motion and high-g events up to ±320g. Time-based and event-based recording, an onboard real-time clock, and a choice of battery capacities accommodate different test requirements. Portable and integrated Screwdown/Strapdown cases are available.
