Telemetry Equipment

In general, telemetry works in the following way: Sensors at the source measure either electrical data (such as voltage or current) or physical data (such as temperature or pressure). These measurements are converted to specific electrical voltages. A multiplexer combines the voltages, along with timing data, into a single data stream for transmission to a remote receiver. Upon reception, the data stream is separated into its original components and the data is displayed and processed according to user specifications.

Telemetry Throughout Time

In 1912, the first telemetrics application in Chicago used telephone lines to transmit operational data from a power plant to a central office. Because telemetry was originally used in projects like this, the first telemetry systems were called supervisory systems. In 1960, the interrogation-reply principle was developed, which allowed a more selective transmission of data upon request. At that time, a telemetry transmitter consisted of a set of measuring instruments, an encoder that translated instrument readings into analog or digital signals, a modulator, and a wireless transmitter with an antenna. The receiver consisted of an antenna, a set of radio-frequency (RF) amplifiers, a demodulator and recording devices. Mainframe computers were used to process and store the received information.

Today, telemetry applications include measuring and transmitting data from sensors located in automobiles, smart meters, power sources, robots and even wildlife in what is commonly called the Internet of Things (IoT).

    Applications

    Now the telemetry help to Remote Monitoring all kind of industrial or common things, ensuring the safety of people and the environment knowing the information that they need wherever they are. We designed state of the art equipment to monitor cathodic protection systems such as:

  • Rectifiers.
  • Test Points.
  • Compressors.
  • Tanks.
  • Other critical assets in the Oil & Gas Industry.

Through a sophisticated network and with a wide coverage of the GSM networks, the information is measured and wireless transmitted to our Web Servers for storage, generating alarms as necessary according to the presets configured during the setup phase. This information can demonstrate the regulatory compliance of your assets.
