T-Node FR/TS210 Register Information
Modbus-RTU Register Information The NexSens T-Node FR/TS210 Temperature string outputs values as 32-bit IEEE 754 floating point numbers in big-endean format. To convert from a hexadecimal value to a decimal value, use an IEEE-754 Floating Point Converter. Insert the hex output (e.g., 0x41af381d) into the “Hexadecimal Representation,” and the “Decimal Representation”, the temperature in degrees […]

Prevent Pressure Build-Up in CB-Series Data Wells
Due to temperature and barometric pressure changes, or in some cases, battery off-gassing, buoys with sealed compartments, including battery and data wells, can build up pressure or establish a vacuum over time. To reduce these effects, NexSens CB-Series buoy lids are equipped with either a membrane vent or, for rough water applications, a 5 PSI […]
