Coupled Multielectrode Sensor Probes

CMS probes are made from user-specified sensing materials, including carbon steels, stainless steels, and nickel-, aluminum-, and copper-based alloys. They can also be made from customer supplied materials that have the same microstructure/heat treatment as the system component materials to be monitored.

The size of the sensing electrode varies from 0.1 to 3 mm (0.004" to 0.12") in diameter, depending on the application. Typical numbers of electrodes in a CMS probe are 9, 16 or 25 for online corrosion monitoring and vary from 8 to 100 for laboratory corrosion and electrochemical studies. Other sizes and numbers of electrodes are available.

CMS Probes with Flush Mounted Electrodes

Typical Applications:

Quantitative Corrosion Monitoring and Electrochemical Studies for:

• Pitting corrosion

• Crevice corrosion

• General corrosion (most types)

• Inhibitor evaluation

• Cathodic/anodic protection

in the following environments:

• Aqueous solution

• Humid gases

• Soil

• Oil-water mixture

 
CMS Probes with Exposed Electrodes

Typical Applications:

Quantitative Corrosion Monitoring of:

• Pitting corrosion

• Crevice corrosion

• General corrosion (most types)

• Cathodic/anodic protection effectiveness

• Coating evaluation

in the following environments:

• Aqueous solution

• Soil

• Oil-water mixture

• Under coating

Exposed electrodes increase the sensing signal for an extremely low corrosion rate and reduce the effect of crevice between the electrodes and the insulation materials. An exposed electrode can be painted with coatings and be used for undercoating corrosion monitoring.

 
CMS Probes for High Temperatures and High Pressures

Typical Applications:

Quantitative or Qualitative Corrosion Monitoring of:

• Pitting corrosion

• Crevice corrosion

• General corrosion (most types)

in the following environments:

• Super critical water systems

• Steam generators

• High temprature and/or high pressure reactors

• High pressure pipelines

• Furnaces

• Fireside of boilers

• Flue gas stacks
