The
measurement of some quantity with the aid of intermediate means which permit
the measurement to be interpreted at a distance from the primary detector. The
process that measures a quantity and then transfers the measurement data to
a remote location to be recorded, displayed, or to control a process. FCC
Definition: "use of telecommunication for automatically indicating or
recording measurements at a distance from the measuring instrument. Strictly
speaking, "telemetry" is the information that is collected, and
"telemetering" is the process that collects and transfers the
information.
Technology advances allow reduction in size and power
requirements. In addition, high speed computers allow the use of complicated
algorithms for detection, encryption, and coding (compression). International
Foundation for Telemetering (IFT) Purpose "The purpose of the IFT is to
promote and stimulate technical growth in the field of telemetering and its
allied arts and sciences. A telemetering system includes all components
that are used to measure, transfer, and analyze the data. Although not all of these components are present in every
telemetering system, and some systems may include other components.

SMCT302
Telemetry Measurement and Control System
Model:
WM-TLMR-SMR-001
The SMCT302 - Telemetry Measurement and Control
System, developed by Smar, is intended to monitor and to control industrial
process variables in applications where the distances involved or the
geographical conditions of the area makes it impractical to use cables.
Some of the chief benefits
of the SMCT302 are:
-
The possibility of performing periodical
measurements without the participation of operators,
-
The reduced cost when compared with
conventional systems that make use of cables as the means of
transmission, and
-
The possibility of using existing
facilities such as telephone lines and transmission towers.
Besides the monitoring and
control of process variables, the SMCT302 provides real time operation and
maintenance, as well as status monitoring of all pieces of equipment
involved in the process, which makes it possible to diagnose eventual
failures in the system. All information collected by the SMCT302 are stored
in a standard format data bank which may be used in reports, process
optimization, statistic control and enterprise administration software. |
