What Permasense does
Permasense Ltd is a UK-based (Horsham) research and development company founded in 2008 that developed continuous corrosion and erosion monitoring technology for industrial process facilities. Originally an independent firm focused on the oil and gas sector, Permasense was acquired by Emerson Electric Co. and now operates as a product brand within Emerson's Measurement Instrumentation division, with its technology sold under the Rosemount brand.
The company's core offering centers on wireless ultrasonic thickness (UT) monitoring. Permanently installed transmitters (Rosemount Wireless ET310C, ET310, and WT210) use patented couplant-free ultrasonic technology — employing dry-coupled waveguides and electromagnetic acoustic transducers — to measure wall thickness without process interruption, transmitting data wirelessly for real-time visibility into metal loss. The portfolio has been extended with the Rosemount 4390 Series of inline fluid corrosivity transmitters, which use probes in direct contact with process fluid for highly sensitive corrosion and erosion measurement, and the Rosemount SAM42 Acoustic Particle Monitor, which listens to solids in the process stream to detect erosion risk in real time. Sensor data is consolidated in Plantweb Insight Corrosion and Erosion Applications, Emerson's analytics platform that delivers predictive intelligence, anomaly detection, and dashboards for asset integrity management, alongside a Connected Services offering for ongoing expert monitoring.
Permasense sells through Emerson's global enterprise field-sales motion with quote-based, multi-year contracts and expert-led configuration. Revenue streams include hardware sales (wireless transmitters and probes), recurring software/analytics (Plantweb Insight), and managed services (Connected Services). End markets are industrial verticals with high asset-integrity stakes — Oil & Gas (upstream and downstream), Refining, Chemical, Mining/Minerals & Metals, Power (including Data Centers), Marine, and Pulp & Paper — where unplanned downtime, safety incidents, and shortened asset life from corrosion and erosion represent material operational and financial risk.
