Access limitations in confined spaces, elevated structures, and offshore installations increase deployment cost and time. Hot-tap requirements and shutdown coordination can delay projects. Offshore logistics and permitting further complicate installations. These access constraints create reliance on specialized service providers. Deployment complexity remains a key barrier to rapid scaling in legacy infrastructure.

• Data Interpretation Variability and False Alarm Risk
  Corrosion signals can be influenced by flow regimes, temperature changes, chemical transients, and sensor placement. Misinterpretation can lead to false alarms, unnecessary maintenance, or missed risks. Operators require clear thresholds, calibration protocols, and contextual process data. Analytics can help, but model validation remains essential. Trust in alarm quality directly impacts adoption of continuous monitoring. Data interpretation complexity continues to be a major operational challenge.

• Harsh Environment Durability and Lifecycle Cost Pressure
  Sensors deployed in high-temperature, high-pressure, or saline environments face accelerated wear and reliability risks. Ruggedization increases upfront cost, while replacement and recalibration increase lifecycle expense. Offshore and subsea deployments require extreme reliability due to access constraints. Materials compatibility issues can affect probe life and measurement stability. Ensuring long-term durability is essential for achieving the expected ROI. Lifecycle cost pressure influences procurement decisions and vendor qualification.

• Integration and Interoperability Challenges with Plant Systems
