SunStation™阴极保护监测

Each SunStation is a single-channel device with an independent ground, thus any Polatrak instrument can output to this device. Anode currents, for example, can now be read directly, in real numbers, as can current densities. This system can save an operator hundreds of thousands of dollars in reduced inspection time, and improves quality and repeatability of data to a level never before available.

The readouts are strategically located where ROV intervention is required; CP inspection is achieved whenever the ROV visits. The mounting panel around the unit indicates inspection point location information and the designation of each channel.
