Overview
RCM sensor uses electrical resistance to measure the corrosion and thinning of metals.
To minimize the effects of temperature changes, the RCM sensor prepares the same pattern and uses one side as a reference for comparison.
Sensor types
We provide various types of sensors for your purpose.
It can be customized to meet your requirements.

Flat type
- Stepless structure, which prevents water accumulation.

Flexible type
- Polyimide is used for substrate instead of glass fiber epoxy.

Overlap type
- For evaluating the amount of corrosion thinning on uneven objects.

Straight type
- Increase the electrode width to reduce the impact of localized corrosion.
Appearance・Structure
In order to increase the value of measured electrical resistance, the metal electrode has an elongated shape. the electrical resistance of the coated electrode is used as the reference electrode to reduce the influence of temperature change, and the corrosion amount is calculated from the ratio of the electrical resistance between the reference electrode and the exposed electrode
