The NexSens T-Node FR Thermistor String provides high accuracy temperature data 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. The nodes are connected in-series using marine-grade UW Cables with braided Kevlar core and double O-ring seals.

Each T-Node FR sensor is accurate to +/-0.075 C for high-precision measurements. 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. The string is powered by 4-28 VDC for operation on a 12 or 24 VDC power supply.

Mating UW Cables are available in lengths from 0.5m to 50m with a maximum 1,219 meters (4,000 feet) or 250 nodes. Strings terminate in a NexSens UW plug and receptacle connector, allowing additional sections or sensors to be added as required. Optional accessories include water quality sensors, pressure sensors, signal splitters, cable clamps, stainless steel mooring line, and communication adapters.
