Summary of all activities of Metallic Construction Materials group is here.
Knowledge of the corrosivity of environment is crucial for the proper optimization of corrosion protection. Implementation of on-line and real time monitoring enables operators to take immediate countermeasures if corrosion is accelerating and decrease thus the negative impact and costs of corrosion.
Resistometric sensors allow for the direct monitoring of corrosivity over time through precise measurements of the sensor's electrical resistance. When the sensor corrodes, its cross-section decreases, leading to a change in its electrical resistance. Based on this change in electrical resistance, the values of corrosion depth loss and the corrosion rate over time can be determined. To compensate the temperature effect on electrical resistance, resistometric sensors have an integrated reference part that is protected from corrosion. Comparing the changes in electrical resistance between the measuring and reference sections of the sensor enables an accurate calculation of the material loss caused by corrosion.

The CorrSen sensors which we use feature high sensitivity and a short response time (as seen in the graph of the corrosion depth loss record above). They are universally applicable in soil, the atmosphere, water, and other liquids without limitations by the conductivity. Unlike most monitoring techniques, these sensors do not require the presence of an electrolyte for corrosion monitoring. We offer a wide range of sensor materials, including steel, copper, zinc, aluminum, silver, and lead. We can also provide custom-made sensors from almost any metallic material or alloy.
We offer:
- Corrosion monitoring design, installation, maintenance, and data evaluation.
- The opportunity to apply CorrSen corrosion monitoring system.

Applications of CorrSen:
- Monitoring of atmospheric corrosion and determining corrosivity classes according to the ISO 9223 standard.
- Indoor monitoring (museums, galleries, archives, server rooms).
- Monitoring in the automotive, aerospace, and marine industries (mapping high-risk areas for corrosion attack, offshore platforms).
- Monitoring of electrochemically protected metallic objects (verifying corrosion protection settings).
- Monitoring of corrosion under insulation (CUI).
Further application possibilities, including detailed information, are described at www.corrsen.com.
