ICP analyzer
The ICP Analyzer is a portable microprocessor device and is designed for operational maintenance of ICP Corrosion Process Indicators with the ability to store and transfer data from the analyzer's memory on the status of indicators to a computer.
The analyzer, when connected to the indicator, performs its initialization, identification, scanning of the state of the indication elements, data exchange with the indicator memory chip, calculation and indication of the corrosion rate and depth.
Corrosion indicator
ICP indicators are designed to assess the corrosion state of a steel underground structure. The data obtained during the operation of the indicators are expressed in terms of corrosion rate (mm/year) and the total depth of corrosion since the indicator was installed (mm). Data from the indicator is processed by the ICP Analyzer.
Indicators have several modifications that differ in the number of display elements and their thickness. The display elements are characterized by a normalized thickness of the bottom of the monolithic housing cavity. Marking of indicators is carried out according to the scheme below:
ICP AA-VVV M, where:
ICP – abbreviated letter designation of products;
АА – is the number of display elements, a number from 01 to 99;
VVV – thickness step of display elements in tens of microns;
M – monolithic body.
For example, the record IKP10-012M denotes a corrosion process indicator, consisting of ten display elements with a thickness step of 120 µm, in a monolithic case.
The indicators are installed permanently in the ground with the conductors brought out to the control and measuring point (CIP) or carpet.
