Meaning of telemetry (what is it, concept and definition)

What is Telemetry:

It is known as telemetry to the system which allows monitoring, mediation and / or rastreamiento of physical quantities or chemical through data is transferred to a central control.

The telemetry system is normally carried out using wireless communication, but it can also be done through other means such as: telephone, computer networks, fiber optic link, among others. Telemetry is used in very diverse areas ranging from motorsports, aviation, astrology, through agriculture, the oil industry, medicine and even biology.

Telemetry aims to allow the mediation of physical or chemical quantities, to know the states of the processes and the system, as well as to remotely control the operation, correct errors and send the information collected to an information system for its use and benefit..

The telemetry system works by means of a transducer as an input device, a transmitter means in the form of cable lines or radio waves, signal processing, a recording device or data display. The main function of the transducer is to convert the physical or chemical magnitude such as: temperature, pressure, vibrations, voltage, into an electrical signal, which is transmitted remotely in order to be recorded and measured.

Telemetry allows monitoring liquid levels in rivers, containers, tanks, among others, allows measuring fluid parameters such as temperature, pressure, flow rates, and monitoring the environment such as the property of wind, water, air, and detect gases dangerous to it. Similarly, it foresees when a natural disaster such as a tsunami may occur, through radio telemetry, which measures the behavior of waves and sizes.

Etymologically, the word telemetry is of Greek origin " tele " which means "distance" and " metry " which expresses "measure".

Vehicle telemetry

Vehicle telemetry provides insight into engine performance, aerodynamic efficiency, oil pressure, tire grip, brake wear, and other car measurements that are important to the driver's progression in the race.

Telemetry in medicine

Telemetry in medicine consists of measuring or recording electrocardiographic processes at a distance. Specifically, these records are observed in a central computer located in the infirmary, where it is possible to obtain knowledge of the electrocardiograms of all the patients connected by means of wireless radio transmitters.

Spatial telemetry

Space telemetry allows measurements made on board the satellite to be obtained from the ground, which is of utmost importance for human safety. On the other hand, it allows controlling flight tests and verifying planes, probes, missiles, among others.
