T-Node FR Temperature Sensor
The NexSens T-Node FR Temperature Sensor provides high precision measurements in a connectorized and addressable architecture for water quality profiling.
Each node features an integral titanium thermistor secured and epoxied in a protective housing for underwater deployments.
Nodes are connected in-series using marine-grade cables with braided Kevlar core and double O-ring seals. Cables are available in increments from 0.5m to 50m.
Each sensor is accurate to +/-0.075 C. The exposed titanium thermistor makes direct contact with water, allowing readings to stabilize within 60 seconds.
Temperature data is transmitted on a RS-485 Modbus RTU string bus for integration with data loggers and SCADA systems.
Optional accessories include water quality sensors, pressure sensors, signal splitters, cable clamps, mooring line, and communication adapters.

There are many major rivers flowing through the Pacific Northwest. Like others around the country, they are outfitted with various dams and reservoirs that are used to control their movements, provide energy and maintain drinking water supplies for those living around them. The U.S. Army Corps of Engineers (USACE) plays a big hand in managing and maintaining the structures that corral these rivers. Of significance for engineers with the USACE’s […]Read More →
Lake Erie’s western basin has received a lot of attention in recent years, as it has hosted large and toxic algal blooms that seem to come every summer. But there are still plenty of valuable environmental data to be gleaned from studying in the lake’s deeper and less algae-prone eastern basin. Researchers at Buffalo State University know the value of monitoring in this basin firsthand, as they have maintained a […]Read More →
Jordan Pond is one of the most transparent lakes in Maine, but the water body has seen cloudier waters in recent years. Declines in clarity began back in the 1990s and the drops appeared to accelerate, with monitoring by the National Park Service charting a 2-meter drop in Secchi disk readings there from 1999 to 2014. Several hypotheses were put forth for the lake’s loss in clarity. Scientists suspected that […]Read More →
