Summary: AN INTRODUCTION TO TELEMETRY
PART 1: TELEMETRY BASICS
Telemetry is defined as the sensing and measuring of information at some remote
location and then transmitting that information to a central or host location. There, it
can be monitored and used to control a process at the remote site.
The basic concept of telemetry has been in existence for centuries. Various mediums
or methods of transmitting data from one site to another have been used. Dataradio
provides a wireless method for transmitting the information. Telemetry using radio
waves or wireless offers several distinct advantages over other transmission
methods. Some of these advantages are:
· No transmission lines to be cut or broken.
· Faster response time
· Lower cost compared to leased lines
· Ease of use in remote areas where it is not practical or possible to use wire or
· Easy relocation
· Functional over a wide range of operating conditions
Properly designed radio links can provide low cost, effective and flexible data
gathering systems that operate for many years with very little maintenance.
