Installation scheme of the CMS-PST_ICPD Installation scheme of the CMS-PST_ICPD

The CMS-PST-ICPD is a corrosion monitoring system consisting of a drainage unit for direct and alternating currents induced to the pipeline, which is equipped with a controller and a data transmission channel. The direct current is drained at the condition that the pipeline voltage exceeds the given range.

The system allows to monitor:

  • drained direct and alternating currents;
  • parameters of corrosion situation at the installation place.

Electrochemical protection parameters are measured with a steel coupon of 1qr cm area.
