3.1.2 Configure Your Transmitter

Now that you have connected your USB cable to your PC and transmitter you
will complete the following steps to configure your transmitter before placing
the unit into operation. You will be using the configuration software utility that
you installed onto your PC. If you have not installed the configuration software
utility you should do so now.

During this procedure you will be setting the following parameters in your
connector transmitter.

Thermocouple Type

This will program your device to provide the correct temperature readings to
your receiver for the type of thermocouple you will be using. Available types are
J, K, T, E, R, S, N, B.

RTD Type

This will program your device to provide the correct temperature readings to
your receiver for the type of RTD you will be using.

Connector Address

This sets a unique address number into your connector/transmitter. Later, when
you set up your measurement software you will again set channel numbers to
receive readings from the corresponding unit(s). Each connector must be set for a
different channel number for your system to operate correctly.

If you will be using more than one receiver unit in your area it is important to set
the transmitter address numbers to be a corresponding number in your TC­Central software. See Examples below.
For the first receiver:
Set the channels on your transmitters to 101, 102, 103, 104, etc. Then set the
channels in your TC-Central user software to match.
For the second receiver:
Set the channels on your transmitters to 201, 202, 203, 204, etc. Then set the
channels in your TC-Central user software to match.
This numbering scheme can be expanded to match the number of receivers you
are using.

Sample Rate
This will program your device to transmit 1 data reading to your receiver at a
specified time interval. Available settings are 2, 3, 5, 15, 30, 45, 60, 75, 90 or 120
seconds

The sample rate you set will have the most direct effect on the life of the battery in
your transmitter. It is recommended that you set the longest sample time that your
application can live with to extend time between battery replacement. See Section 6
for more information on battery life.

STEP 1. Enter the “SETUP” mode.

To place your transmitter into the “SETUP” mode for programming follow this

3.2 Mounting, Installation and Antenna Connection

3.2.1 Mounting

The diagram below shows dimensions of the transmitter that allows you to
mount it.

Figure 3-11. Mounting Dimensions

When mounting your transmitter, care should be taken to make sure it is as far
away from any metal objects. If nearby metal gets too close to your transmitter, it
has the potential to interfere with the way the unit radiates and may cause signal
lose or possibly even the inability to communicate at all with your receiver.

3.2.2 Installation

When installing your transmitter it is important to position your device in such a
way as to optimize the antenna location within what’s known as the “Fresnel
Zone”.

The Fresnel Zone can be thought of as a football-shaped invisible tunnel between
two locations that provides a path for RF signals between your transmitter and
your receiver.

ANTENNA

TRANSMITTER ANTENNA

Connector Operation

3-8

In order to achieve maximum range, the football-shaped path in which radio
waves travel must be free of all obstructions. Obstacles in the path (especially
metal) will decrease the communication range between your transmitter and
receiver. Also, If the antennas are mounted just barely off the ground, over half
of the Fresnel zone ends up being obstructed by the earth resulting in significant
reduction in range. To avoid this problem, the antennas should be mounted high
enough off of the ground so that the earth does not interfere with the central
diameter of the Fresnel zone.

It is important to understand that the environment may change over time due to new
equipment or machinery being installed, building construction, etc. If new obstacles
exist between your transmitter and receiver, the devices can be raised on one end or
on both ends to hopefully clear the Fresnel Zone of obstructions.

No co-location with other radio transmitters is allowed. By definition, co-location
is when another radio device or it’s antenna is located within 20 cm of your
transmitter and can transmit simultaneously with your UWXL unit.

Never install UWXL transmitters within 20 cm or less from each other.

Never use your UWXL transmitter as a portable device. Your unit has been
designed to be operated in a permanent installation only.

3.2.4 Antenna Connection

Your device has been shipped to you with a standard antenna already attached. In
some cases the user may wish to install a remote antenna to maximize transmission
range to the receiver. In these instances the UWXL-RAK kit can be used. The kit
includes a direction antenna, 8" extension cable and mounting bracket.

In some cases, a short RF cable may be used to connect an antenna to your device.
Please note that RF extension cables will always add some loss to the transmitting
signal strength. The longer the cable the more signal will be lost over that cable.
Because of this the length of the cable should be kept as short as possible.

Use of any other antenna then what’s supplied with your device will void all FCC
and CE regulatory compliance.

Additional Information on installation and system operation can be found in
Section 6.

3.3 - Thermocouple/RTD Connection

Your transmitter features a screw terminal connection which allows you to
connect a wide range of sensors and probes. Models with integral probes are
available from the factory. To connect a wire thermocouple or RTD, first remove
the nut from the cable gland and put the wire through the nut and seal. Then
feed the wire up through the cable gland fitting and around the outside of the
PCB mounting bracket. Connect the wires to the proper terminals on the
terminal block and then position the wire so that it does not interfere with the
housing cap when installed. Once the wire is positioned you can remove any
slack and tighten the cable gland nut to seal around the wire.

Figure 3-13. Thermocouple/RTD Connection

3.3.1 Thermocouple Operating Environment and Placement

3.3.2 Ambient Temperature Concerns

Your transmitter is rated for use in ambient temperatures between -10°C (14°F)
to 70°C (158°F). Exposure to temperatures below or above these stated
temperatures can cause your device to malfunction and produce incorrect
operation. When installing your thermocouple probe care should be taken to
make sure your transmitter will not be operated in an environment outside the
specifications outlined in Section 7.

Installing your transmitter in an application were the device will be exposed to
ambient temperatures above or below the operating limits specified in this manual
will damage your unit and cause the unit to malfunction and produce incorrect
operation.

CAUTION:

Lithium batteries may get hot, explode or ignite and cause serious injury if exposed to abusive
conditions. Be sure to follow the safety warnings listed below:
Your transmitter operates with one 3.6V Lithium Battery. Omega Replacement Part Number UWTC-BAT-C.
Never operate your transmitter with a different battery than what is specified in this manual or on the
product data sheet.
Do not discharge the battery using any device except your Transmitter unit. When the battery is used
in devices other than the specified device, it may damage the battery or reduce its life expectancy. If
the device causes an abnormal current to flow, it may cause the battery to become hot, explode or
ignite and cause serious injury.
Refer to the Omega technical data sheet or this manual for the temperature ranges over which the
battery can be operated. Use of the battery outside this temperature range may damage the
Transmitter or reduce the performance and life of the battery.

• Do not place the battery in fire or heat the battery.

• Do not store batteries with other hazardous or combustible materials.

• Do not install the battery backwards so the polarity is reversed.

• Do not connect the positive terminal and negative terminal of the battery to each other with any

Section 4 - System Operation

4.1 Introduction

Compared to wired thermocouple systems, wireless thermocouple systems
provide much simpler installation. Based on the physical principle of the
propagation of radio waves, certain basic conditions should be observed. The
following simple recommendations are provided to insure proper installation
and correct operation of your UWXL Series system.

4.2 RF Communication Basics

The Model UWXL wireless Thermocouple Transmitter sends wireless
transmissions to the UWXL-REC1 receiver. The receiver checks the incoming
data for accuracy and processes this data for use by the measurement software
on your PC. Radio signals are electromagnetic waves, hence the signal becomes
weaker the further it travels. While radio waves can penetrate some solid
materials like a wall, they are dampened more than when a direct line-of-sight
between the transmitting and receiving antenna exist.

4.3 Basic System Overview

The UWXL wireless thermocouple system is comprised of only two main
components; a Thermocouple Connector with a built-in battery powered 2.4
GHz radio transmitter, and a USB powered 2.4 GHz radio receiver.

Figure 4-1. Basic System Overview

Up to 48 UWXL transmitters can be used with one Model UWXL-REC1 receiver.

4.4.2 Ambient Temperature Readings

The ambient temperature reading displayed on your screen when running the
TC-Central program, is the actual ambient temperature that your transmitter is
being exposed to. This reading is only provided as reference and to aid you in
proper installation of your unit. The ambient temperature reading will blink and
change to RED digits to alert you that your have exceed the maximum
recommended safe operating conditions for your transmitter. You should not
rely on this feature as sole protection. Additional protection should be taken by
you “the user” to protect your unit from extreme conditions.

Operating your transmitter outside the specified ambient conditions listed in
Section 9 of this manual may cause your unit to malfunction and stop working
correctly.

4.5 Environment/Operating Conditions

4.5.1 Environment

Omega’s UWXL series transmitters are designed to be fixed mounted and
operated in either indoor or outdoor environments. Care should be taken to
prevent the components of your wireless system from being exposed to toxic
chemicals and extreme hot or cold temperatures outside the specifications listed
in this manual.

4.5.2 Operating Conditions

The following is a list of basic good practice you should apply when operating
your wireless system.

• Never operate your wireless device outside the recommended
environmental limits specified in this manual.

• Never operate your wireless device in flammable or explosive
environments.

• Never use your wireless device in medical, nuclear or other dangerous
applications were failure can cause damage or harm.

• Never operate your transmitter with any other battery or power source than
what’s specified in this manual or on the battery compartment label.

• No co-location with other radio transmitters is allowed. By definition, co­location is when another radio device or it’s antenna is located within 20 cm
of your transmitter and can transmit simultaneously with your UWXL unit.

• Never install a transmitters within 20 cm or less from each other.

• Never use your transmitter as a portable device. Your unit has been
designed to be operated in a permanent installation.

• Never install and/or operate your transmitter closer than 20 cm to nearby
persons.

• Never operate your transmitter with any other antenna than what is
supplied or listed here in this manual for approved use.

NOTE:

4.6 Determining and Maximizing Range

The available maximum range specified for the wireless Series system in this
manual is only achievable under optimum installation conditions. Mounting
height, obstructions in your “Fresnel Zone” and ambient conditions can cause a
decrease in signal strength resulting in a shorter range between your transmitter
and receiver unit.

The following recommendations will help to improve the range of your wireless
system.

Position your receiver in a central location

When multiple transmitters are in operation, position your receiver unit in a
central space if possible in equal distance to each connector transmitter.

Figure 4-4. Determining Maximum Range

Test your system before permanent mounting

Before permanently mounting your transmitters in your application try moving
the devices to different locations and mounting angles to determine what
installation achieves the best signal strength.

Move your system components higher off the floor and away from exterior walls

Avoid installing your system components to close to the floor or near your
buildings exterior walls. The closer your transmitter and receiver unit are the
greater the interference and lose of signal strength will be.

Maintain a line of sight (LOS) between antennas

Maintaining a line of sight between your transmitter and receiver unit will
produce greatly improved signal strength over a system were the antenna’s in
your system have obstacles blocking them.

Maintain a constant ambient temperature environment

Maintaining a constant ambient temperature environment is important to
achieving maximum signal strength. Exposing your system components to
extreme hold or cold temperatures, or sudden changes in ambient conditions
will have an effect on the performance of your system.

4.6.1 Operation in Buildings

Your transmitter sends wireless data transmissions to a receiver connected to
your PC. Radio signals are electromagnetic waves. A radio signal becomes
weaker the further it travels. Range is decreased by different types of materials
found in the direction of the signals propagation. Radio waves can penetrate
most types of wall materials, but they are dampened more than they would be
by a direct line-of-sight installation.

4.6.3 Building Materials

Examples of how different types of wall material may reduce your signal:

Material Type Possible Signal Reduction

Wood, Plaster, Sheetrock, Uncoated 0 to 10%
Glass w/o Metal, Fiberglass

Brick, Pressboard 5 to 35%

Reinforced Concrete 10 to 90%

Metal Walls, Metal Doors, Elevators,
Metal Stair Cases, Metal Piping, 90 to 100%
Metal Mesh, Metal Screening

Figure 4-5 Operation In Buildings

Avoid dampening materials by repositioning the transmitting and/or receiver.

4.6.2. Penetration Angle of Radio Waves Through Walls

The angle at which the transmitted radio signal hits a wall is very important and
also has a big effect on maximizing range. Signals between your transmitter
should be transmitted as directly as possible.

NOTE:

4.7 Antenna Basics

4.7.1 Antenna Basics

By definition, an antenna is a device used to transform an RF signal, traveling on
a conductor, into an electromagnetic wave in free space. Antennas demonstrate a
property known as reciprocity, this means that an antenna will always maintain
the same characteristics regardless if it is used to transmit or receive. Most
antennas are resonant devices, which means they operate efficiently over a
relatively very narrow frequency band. An antenna must be tuned to the same
frequency band of the radio system to which it is connected, otherwise the
reception and the transmission will be impaired. The antennas in your wireless
thermocouple connector system have been tuned to operate in the 2.4 GHz band.

In some cases, a short RF cable may be used to connect an antenna to your
device. Please note that RF extension cables will always add some loss to the
transmitting signal strength. The longer the cable the more signal will be lost over
that cable. Because of this the length of the cable should be kept as short as
possible.

4.8 Antenna Placement

Proper antenna installation is important and will allow you to achieve maximum
performance and range between your transmitter and receiver unit.

Your transmitter should not be installed on the same side of the wall as the
receiver. If mounted close to each other on the same wall, the radio waves are
likely to be subject to interfering dispersions or reflections. The best positioning is
to have the transmitter installed on the opposite or connecting wall to the receiver.

4.8.1 Horizontal Antenna Placement

Figure 4-6. Horizontal Antenna Placement

If your transmitter is mounted in a horizontal position in your application you
should mount your receiving so that the same polarization is achieved with the
receiving antenna. As shown in the “Horizontal” example above.

4.10 Transmit Rate vs. Battery Life

Many factors such as ambient temperature
conditions and transmitting rate can have a big
effect on the life of the battery used in your
transmitter. Transmitting data places a big
demand of the battery in your transmitter. The
transmit rate is the single most contributing
factor in the life of your battery. The slower the
transmit rate you set, the longer the battery in
your device will last. The table below give some
estimates on how long the battery should last vs.
the transmit rate you selected when you setup
your transmitters and under normal operating
conditions.
