NexSens T-Node Water Temperature Sensor

Details:

The NexSens T-Node connectorized water temperature sensor features an integral digital sensor secured in a protective housing for underwater deployments down to 100 meters in fresh, brackish, or seawater. Each T-Node sensor is factory calibrated to +/-0.1 C for high-precision measurements. The sensors can be connected in-series using UW underwater cables and suspended vertically in a water column or horizontally along a stream or riverbed. Double o-ring seals ensure a waterproof sensor connection.

Temperature data is transmitted on a 1-wire temp string bus. In addition to the 1-wire bus, the T-Node offers pass-through signals for SDI-12 and RS-485, allowing the user to connect Nodes and other environmental measurement sensors along the string. This sensorBUS architecture has been designed so that researchers can easily build and customize multi-point temperature strings or more powerful environmental monitoring networks.

The T-Node sensors feature a plug-and-play interface to NexSens SDL500 submersible data loggers and offshore data buoys. Data collection options include standalone, radio, and cellular telemetry. NexSens iChart Software is a Windows-based program for interfacing both locally (direct-connect) and remotely (through telemetry) to an SDL500 data logger or network of data loggers. For connection to external data collection platforms, the T-Node sensor string can integrate with a NexSens controller for data output in SDI-12 or Modbus RTU.
