The X2-SDL Submersible Data Logger is a rugged, self-powered data logging and telemetry system for deploying environmental sensors in or near water without fear of accidental flooding.
- QUICK SPECS
RuggedThe X2-SDL is designed with impact-resistant PVC, two elastomer bumpers, shock-mounted electronics and redundant seals. It can withstand extreme wave action, floods and underwater deployment to 200 ft.
Underwater ConnectorsAll connections are made with a simple waterproof thread-in connector. This removes the complications and errors associated with connecting individual wires.
Extended Battery LifeThe X2-SDL operates for months on sixteen D-cell alkaline batteries. For longer deployments, extra alkaline battery packs and solar charging options are available.
Device-to-WebWhen communicating via wireless telemetry, measurement data streams directly to the WQData LIVE web datacenter.
Communication OptionsReal-time telemetry options include cellular, satellite, and radio. All communication modules are securely housed within the submersible enclosure, and a waterproof antenna is integrated on the top of the device.
Measurement VersatilityThe X2-SDL is configured with three sensor ports to interface with multi-parameter sondes, water quality sensors, temperature strings, Doppler velocity meters, water level sensors, and more. Supported sensor interfaces include SD-12, RS-485 and RS-232.
Buoy IntegrationThe CB-50 data buoy is designed to accommodate the NexSens X2-SDL submersible data logging system for unattended deployment in lakes, rivers, and coastal waters.
