NexSens TS-Clamp thermistor string mooring clamps allow TS210 and T-Node FR nodes to be securely attached to a mooring line. Follow these steps to ensure a proper installation of the TS-Clamp: 1. Unscrew the TS-Clamp to find two o-rings with cuts. 2. Place the large o-ring on the cable above the strain relief of […]
NexSens T-Node FR and TS210 temperature strings have an RS-485 Modbus output that allows direct connection to a Modbus master device (i.e. PLC). To connect the string, a UW receptacle to flying lead cable is required. These cables are available in lengths ranging from 1m to 100m. The wiring for the T-Node FR or TS210 […]
Symptom Possible Cause Corrective Action Temperature data is displayed as a value between -99999 and -100001 Leakage into a connector Check each underwater connection for flooding String disconnected (or severed cable) Check the physical setup and condition of the temp string No Power If connected to port P1 or T ensure switch power is setup […]
Very little maintenance is required for T-Node FR temperature strings because they are designed for long-term deployments in submersible applications. Cleaning Any bio-fouling that accumulates on T-Node FR temperature strings during deployments should be cleaned using a soft cloth or soft-bristled brush along with soap and water. Never allow moisture to enter any of the […]
Temperature strings are frequently attached to mooring lines to keep them fixed in place vertically within a water column. This technique helps to ensure that temperature data is consistently being monitored at desired depths. To mount the T-Node FR sensors to a mooring line, T-clamp sensor mooring clamps, cable ties and a mooring line will […]
T-Node FR sensors can be connected to any iSIC data logger using a UW receptacle to flying lead cable assembly. First, plug the temperature string into the UW receptacle. Run the cable through a gland fitting on the bottom of the iSIC enclosure. Then, wire the flying lead end of the cable into […]
UW underwater connectors provide a plug-and-play interface for connection to NexSens SDL500 Submersible Data Loggers. The SDL500 sensor bulkhead includes sensor connection ports identified as T, P1, P0, A and D. T-Node FR sensors and strings can be connected to Ports P0, P1, T, or D. It is recommended to connect to port […]
Single-Point Temperature String Assembly Single-point strings are used to determine water temperature at one location, typically at the surface. To assemble a single-point temperature string, first connect the male UW plug connector on the T-Node FR to the female UW receptacle connector on an Underwater Cable. Then connect the supplied UW underwater plug […]
