Section 7 - System Operation
7.1 Introduction
Compared to wired systems, wireless 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 UWTC Series system.
7.2 RF Communication Basics
In a basic UWTC series system, the UW series transmitter sends wireless
transmissions to the UWTC-REC1-915 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.
With the UWTC-RPT1 repeater in your UWTC series system, you are able to
maintain a strong signal over a long distance. The UW series transmitter sends
wireless transmissions to the UWTC-RPT1 repeater. The repeater serves as a
signal extension; it receives the incoming data and transmits it to the receiver.
The receiver then checks the incoming data for accuracy and processes it for use
on your measurement software.
7.3 Basic System Overview
Figure 7-1. Basic System Overview
The UWTC wireless thermocouple system is comprised of three main
components; a Thermocouple Connector (with a built-in battery powered 2.4
GHz radio transmitter), a Wireless Repeater (with a 2.4 GHZ receiver and 915
MHz transmitter), and a USB powered 915 MHz receiver.
Up to 48 of each Model UWTC connector/transmitters can be used with one
UWTC-RPT1 repeater.
