Measurement complex of telemetry system

Description

Telemetry autonomous measurement system is intended for measurement of protective potential (total and polarization potential), corrosion rate of underground metal structures with further transmission of this data via GSM channel to the control station. The system is intended for long-term autonomous operation, does not require external power sources and operates in combination with hardware and software package “System monitoring program” or other customized programs.

The system includes:

  • - autonomous power system consisting of two chemical power sources and ultracapacitors;
  • - telemetry unit with GSM module placed in a metal cabinet and attached to the test station stand
  • - copper-sulfate reference electrode
  • - wire indicator unit
