Istallation scheme of CMS-PST-TS
Description of CMS-PST-TS
The CMS-PST-TS is a corrosion monitoring system ensuring monitoring of electrochemical protection parameters at test stations located in different areas of hazard corrosion zones and structural elements of the protected objects.
Operating principle
The system allows to monitor corrosion parameters where at the same time up to 4 reference electrodes are installed with coupons:
- earth, drainage, and protector-group currents (up to 12 current-measuring channels);
- insulation quality (voltage drop at current-measuring leads);
- "pipeline – casing" resistance;
The system can contain a rheostatic resistance control unit RCU (up to 2 channels, up to 14A).
