What is the T1/T1R?
The Seametrics T1 and T1R are highly accurate, submersible temperature sensors. They
are available in both a recording and a non-recording version. Communicating either via
Modbus®RTU or SDI-12, these temperature sensors are versatile and easy to use.
The T1 and T1R temperature sensors are designed to provide trouble-free submersible
operation when properly installed.
The T1 (non-recording version) operates on an external (9 to 16 VDC) power supply and is
ideal for use with many data loggers and SCADA systems.
The T1R (recording version) operates on either two internal AA batteries or an external (6 to
16 VDC) power supply. The unit is programmed using our easy-to-use Aqua4Plus control
software. Once programmed it will measure and collect data on a variety of time intervals.
The T1R can be used as a stand-along unit or network with other Seametrics AquiStar®Smart
Sensors,aswellaswithmanydataloggersandSCADA systemsusing Modbus®RTU orSDI-12.
Initial Inspection and Handling
Upon receipt of your smart sensor, inspect the shipping package for damage. If any
damage is apparent, note the signs of damage on the appropriate shipping form. After
opening the carton, look for concealed damage, such as a cut cable. If concealed damage
Check the etched label on the sensor to be sure that the proper range and type were
provided. Also check the label attached to the cable at the connector end for the proper
cable length.
INTRODUCTION
Do handle the device with care.
Do store the device in a dry, inside
area when not in use.
Do install the device so that the
connector end is kept dry.
Don’t support the device with the connector.
Use a strain relief device to take the
Don’t allow the device to free-fall down a well
as impact damage can occur.
Don’t bang or drop the object on hard objects.

Sensor: There are no user-serviceable parts. If problems develop with sensor stability or
accuracy, contact Seametrics. If the sensor has been exposed to hazardous materials, do
Cable: Cable can be damaged by abrasion, sharp objects, twisting, crimping or crushing
and pulling. Take care during installation and use to avoid cable damage. If a section
of cable is damaged, it is recommended that you send your sensor back to replace the
cable harness assembly.
Connectors (if used): The contact areas (pins & sockets) of the connectors will wear
out with extensive use. If your application requires repeated connections, other types of
connectors can be provided. The connectors used by Seametrics are not submersible,
but are designed to be splash-resistant.

Installation
Lower the sensor to the desired depth. Fasten the cable to the well head using tie wraps
or a weather proof strain-relief system.
If your sensor comes with a connector, be sure the supplied cap is securely placed on the
weather-resistant connector at the top of the cable when not connected to a computer or
logger. Do not install such that the connector might become submerged with changing
weather conditions. The connector can withstand incidental splashing but is not designed
to be submerged.
The sensor can be installed in any position. Strapping the sensor body with tie wraps or

Factory calibration values are set at the factory.
Writing to Factory Calibration registers will void calibration!!
Field calibration values can be set by user. If set, these values will be applied to readings
before values are returned.

Sensor Conguration/Control
40301=n Set averaging: This enables sensor for n seconds (Read/Write).
Each second, the statistical data registers will be update to contain
new averages, max and min. At the completion of n seconds, the
will be put to sleep. n = 0..10,800. If n = 0, the sensor is put to
sleep, and the statistical data values are not updated.
40401=a Set sensor address = a (Write Only)
40501=b Set baud rate according to b (Write Only)
b=0:38400 b=1:19200 b=2:9600 b=3:4800 b=4:2400 b=5:1200
40601=w Set auto-enable. Causes sensor to be enabled automatically for
w seconds after a read of any parameter data register. W=0
disables auto-enable. (This is normally set to 10 seconds at the
factory.)
For lowest power usage, set this to zero. For fastest readings while still retaining as much
power savings as possible, set slightly longer than your read frequency. See section on
40701=L Set serial number. L= unsigned longword value
0x0000000 .. 0xFFFFFFF (0 .. 4,294,967,295)
LSB = minor revision. E.g., 0011 = revision 0.11

OPERATIONS-T1 NON-RECORDING
Readings and the Auto-Enable Setting
When a reading is requested, four things happen:
1. The sensor wakes up.
2. The current value in the register is returned.
3. The sensor turns on the analog portion, begins sampling, and begins putting the
new values in the registers.
sampling and moving values into the registers all the while, and then goes to
sleep.
the reading in the register.
If your read frequency is less than the auto-enable value, the sensor will stay on
reading.
If your read frequency is greater than the auto-enable value, the following reading
sequence is recommended:
1. Request a reading. This begins the wakeup process on the sensor and returns the
value currently in the register, which will be old data. Throw this value away.
2. Wait one second, and then take another reading. This reading will have fresh data.
Record this reading.
Note: This sequence applies only to Modbus®direct read. If reading the sensor via SDI-
12, the warmup timing is automatically taken care of.
