Introduction
What is the T1/T1R?
The 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. Both the T1 and T1R are compatible with INW’s
WaveData®VZCOM wireless data collection technology, making them excellent for
remote monitoring.
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 internalAAbatteries or an external
(6 to 15 VDC) power supply. The unit is programmed using INW’s 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 INWAquiStar®Smart Sensors, as well as with many data loggers and SCADA
systems using Modbus®RTU or SDI-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 is found, immediately file a claim with the carrier.
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.

Do’s and Don’ts Don’t support the device with the connector.
Use a strain relief device to take the
tension off the connectors.
Don’t allow the device to free-fall down a
well as impact damage can occur.
Don’t bang or drop the device on hard
objects.
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.

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 tape will not hurt it. If the sensor is being installed in a fluid environment other than
water, be sure to check the compatibility of the fluid with the wetted parts of the sensor.
INW can provide a variety of seal materials if you are planning to install the sensor in
an environment other than water.
Maintenance
Sensor: There are no user-serviceable parts. If problems develop with sensor stability
or accuracy, contact INW. If the sensor has been exposed to hazardous materials, do
not return it without notification and authorization.
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 INW are not submersible, but
are designed to be splash-resistant.
Trouble Shooting
Erratic Readings
Erratic readings can be caused by a damaged sensor, damaged cable, poor connections
or improper operation of readout equipment. In most cases, erratic readings are due
to moisture getting into the system. Assuming that the readout equipment is working
7
correctly, the first thing to check is the connection. Look for moisture between
contacts or a loose or broken wire.
Erratic and erroneous readings can also occur due to improper grounding.
See Grounding Issues.
Zero Readings
Continuous zero readings are caused by an open circuit which usually indicates broken
cable, a bad connection, or possibly a damaged sensor. Check the connector to see if a
wire has become loose, or if the cable has been cut. If neither of these appears to cause
the problem, the sensor needs factory repair.
Grounding Issues
It is commonly known that when using electronic equipment, both personnel and equip-
ment need to be protected from high power spikes that may be caused by
lightning, power line surges, or faulty equipment. Without a proper grounding system, a
power spike will find the path of least resistance to earth ground – whether that path is
through sensitive electronic equipment or the person operating the equipment. In order
to ensure safety and prevent equipment damage, a grounding system must be used to
provide a low resistance path to ground.
When using several pieces of interconnected equipment, each of which may have its
own ground, problems with noise, signal interference, and erroneous readings may be
noted. This is caused by a condition known as a Ground Loop. Because of natural re-
sistance in the earth between the grounding points, current can flow between the points,
creating an unexpected voltage difference and resulting erroneous readings.
The single most important step in minimizing a ground loop is to tie all equipment
(sensors, dataloggers, external power sources and any other associated equipment) to
a single common grounding point. INW recommends the following: (1) the sensor
cable shield (the wrapped shield inside the cable) be attached to the power ground on
the datalogger and (2) the grounding lug be connected via a 12 AWG or larger wire, to
a grounding rod driven into the earth. It is also recommended that if you are using an
external power supply to power the datalogger that it be tied to the same earth ground.
Notes:
• Proper grounding is very important! If your sensor does not come with a
connector, INW recommends the following:
(1) the sensor cable shield (the wrapped shield inside the cable) be attached to
the power ground on the datalogger and (2) the grounding lug be connected
via a 12 AWG or larger wire, to a grounding rod driven into the earth. It is
also recommended that your power supply be tied to the same earth ground.

Sensor Configuration/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
final statistical values will be left in the registers, and the sensor
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.
