Wireless ConsiderationsChapter 1
Why Go Wireless ?
•Wireless Units are easily re-usable i.e. temporary installation
•No long and costly wiring lay outs
•Non contacting for precision or rotating measurements i.e. temp, pressure, RPM, torque
•Wireless link can cost less than buying and installing a cable
•Easy to Seal
•Eliminates Failure due to Cable damage
•Long Battery Life
•Radio communication is highly regulated
•New and maybe unfamiliar aspects of RF such as antenna positioning and RF interference sources
•Planning, buying and testing a wireless link may cost more initially
•Access is usually still required for changing or recharging of batteries
PROsCONs
T24 - Wireless Considerations
• Range How far must data travel ? Nominal range “open field range” ACTUAL range depends on environment
• Data What type of data and how fast ?
• RF Interference 2.4 GHz is a busy part of the RF
spectrum Radio Signals can be intercepted &
Jammed Installations in proximity must be
co-ordinated

Modular Design & System Examples
Chapter 3
Modular design focused on your application
The T24 range has been designed so that one acquisition module can provide data to
multiple output devices and accept data from multiple acquisition modules.
Acquisition Module
Displays
Rugged Handhelds
Analogue Outputs
Serial Outputs
Printer Module
PC Interfaces
Simple links for simple solutions
Acquiring inputs from multiple or single sources to static and portable displays allows operators
to monitor their sensor data in real time.

Display Module
T24-HSHandheld
Display and log your data in the field
Acquiring data from multiple inputs can simply be displayed or logged to any RS232 display or data
logger. Alternatively a single acquisition module output can be represented as an Analogue output.

On-site computer? On-site logging and monitoring
On-site PC terminals are commonly available and can easily be used to gather and log data from
multiple acquisition modules on-site. Coupled with custom software for your application, graphical
representations can be created for your sensor data.
