Overview

Overview
The NexSens TS210 Thermistor String provides high precision
temperature measurements for profiling in lakes, streams, and
coastal waters. It features an integral titanium thermistor secured
and epoxied in a protective housing for underwater deployments. A
marine-grade cable with braided Kevlar core help ensure reliability
in extreme environments.
Each 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.
TS210 strings are available standard with 1m spacing or at custom
intervals to meet project requirements. Cable lengths are available
up to 1,219 meters (4,000 feet) with a maximum 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 a bottom pressure sensor, cable
clamps, stainless steel mooring line, and communication adapters.

Multi-Point Temperature String Assembly
Multi-point strings are used to determine temperature at various
locations. Typically of interest are temperature distributions
vertically in a water column or horizontally along a stream or
riverbed.
To add the sensors in the Sensor Properties of the iChart Setup
Device Wizard, highlight the appropriate sensor in the Available
Parameters list. TS210 strings typically begin with Temp00 as the
first node. Click Add to add the number of TS210 devices that are
included in the string. Enter the correct Modbus address of the first
node under Modbus Settings (Default is 1). The software
automatically assigns the addresses of the remaining sensors.
If the sensors are to be connected to Port P1, P2 or T (See
Connecting to an SDL Data Logger below) click Show Detail.
Under Switch Power, select SW.A (12V,200mA). Enter 10 in the
Duration (sec) box.
Click OK to finish.
Figure 2: TS210 sensors must be added individually
WARNING
All o-rings must be
clean and dry before
being used to secure
watertight connections.
NOTE
Always check each
mating connector for an
o-ring before securing
any UW underwater
connection.

Connecting to an SDL500 Data Logger
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.
Figure 4: SDL500 sensor bulkhead
TS210 sensors and strings can be connected to Ports P0, P1, T, or
D. It is recommended to connect to port P1 or T to allow for power
to be removed from the TS210 sensors between readings. If this is
done, ensure Switch Power is setup correctly in iChart (See Multi-
Point Temperature String Assembly above).

Connecting to an iSIC Data Logger
TS210 sensors can be connected to any iSIC data logger using a
UW receptacle to flying lead cable assembly.
Figure 5: UW Receptacle to Flying Lead Cable
First, plug the temperature string into the adapter’s UW connector.
Run the cable through a gland fitting on the bottom of the iSIC
enclosure. Then, wire flying lead end of the cable into the iSIC
digital terminal strip per the wiring diagram shown in Table 4.
