SENSOR DESIGN
CAPCIS measures many different types of corrosion on many different materials in a very wide range of environments and under a variety of operating constraints – geometry, accessibility, temperature and pressure. Where appropriate we will apply standard commercial insert probes designed for pipeline and vessel use. These standard probe types – such as flush mounted and finger electrodes – work very well in the target environments for which they were designed but cannot simply be applied to other applications with different environment geometry and chemistry and different corrosion mechanisms.
Our strong background in corrosion science, coupled with extensive field and
laboratory experience, gives us the skills and credibility
to develop bespoke probes and sensors that are matched
to the corrosion process, the measurement process and
to the chosen environment with minimal prototyping and
validation requirements. Examples include specialist
applications and overlarge / extra small variants on
‘standard’ designs. Specialist examples
include:
- localised corrosion probes to simulate individual pit growth,
- multiple element weldment probes,
- concrete durability probes for radiated environments,
- probe systems to monitor corrosion under pressure in aerosol cans
Examples of size constrained probes include:
- Large robust 3 electrode probes for immersion under flowing conditions in sewage treatment works
- Micro 3 electrode probes for measurement in nuclear reactor and boiler environments and insertion through narrow fittings in autoclave vessels
- Thermal gradient biofilm probes to simulate heat exchanger conditions
In each case a sound knowledge of the electrochemistry and microbiology behind the corrosion process is a key ingredient for success.
