Details

The SDL500 Submersible Data Logger is a rugged, self-powered remote data logging system for deploying environmental sensors in streams, rivers, wetlands, coastal waters, sewers, and culverts without fear of accidental flooding. The system is configured with five sensor ports for connection to industry-standard digital and analog interfaces including RS-485, SDI-12, 1-wire temp string, 0-2.5 VDC, pulse count, and more. Each sensor port offers a UW receptacle with double O-ring seal for a reliable waterproof connection. Unlike many data loggers, the SDL500 is truly submersible. The housing and battery compartment are completely sealed and waterproof.

When it comes to field ruggedness, the NexSens SDL500 is in a class of its own. The housing is constructed of impact-resistant PVC and includes two elastomer bumpers for long-term deployment in close-fitting pipes and buoy ports. Internal circuit boards and communication modules are shock mounted and all access ports incorporate redundant sealing. The SDL500 withstands extreme wave action, drops, floods, periodic & long-term deployment underwater, and more. When fitted for wireless remote communication, the radio, cellular, and satellite antennas are also waterproof.

The SDL500 can be powered autonomously by eight D-cell alkaline batteries. Optional solar power kits provide long-term continuous operation and solar charging. The data logger incorporates the same analog and digital interfaces as the popular NexSens iSIC data loggers. Common sensor connections include multi-parameter sondes, water quality sensors, temperature strings, Doppler velocity meters, water level sensors, rain gauges, and weather stations. User-supplied sensor cable assemblies can also be connectorized and tested at the factory for SDL500 integration. With this sensor interface versatility, the measurement possibilities are endless.

NexSens AccuStage water level sensors are simple and durable

For monitoring water level and wave height, NexSens AccuStage water level sensors are durable, easy to use, and require little maintenance. Users can choose between titanium or stainless steel constructions. The sensors work by transducing water pressure into a millivolt charge, which can then be interpreted by data loggers as water level or wave height, depending on user needs. Two models of the sensor, vented or absolute, provide easy interfacing with NexSens iSIC or submersible data loggers. The sensors can communicate through Modbus RS485 or analog. “They’re used in streams and lakes most commonly,” said Kevin Stevens, product manager. “Many customers use deployment pipes, just to keep it more secure, and some also use conduit to protect the cable.

Strands linking system-wide Lake Superior food web identified in study

An inch-long crustacean spends its days near the bottom of Lake Superior, then swims up hundreds of meters under the cover of darkness to feast on plankton growing near the surface. That daily migration of the shrimp-like Mysis diluviana is an important interaction between two nutritional pathways in Lake Superior — one based on lake-bottom sediments and another on plankton growing in the water column. It's one strand in the system-wide food web that links the seemingly separate worlds of the nearshore and offshore habitats in the largest freshwater lake by area on the planet. A recently published study describing these food web links in Lake Superior is one of the first to show cross-habitat interactions in a such a large lake.
