Executive Summary & Core Capabilities
The Rosemount™ Wireless WT210 Corrosion and Erosion Transmitter (formerly Permasense WT210) is a non-intrusive, battery-powered ultrasonic wall thickness monitoring system engineered for high-temperature industrial piping and pressure vessels. Designed to operate without liquid couplant or process shutdowns, the transmitter continuously calculates metal loss with sub-10 micron precision and delivers real-time trend analytics to facility management software.
- Zero Process Downtime: Attaches directly to the outside of pipes and vessels without drilling, cutting, or interrupting fluid flow.
- No Maintenance Required: Operates on an internal high-capacity battery pack for up to 9 years without maintenance or couplant replenishment.
- Weld-Free Universal Installation: Optional Universal Mount strap kit enables rapid installation on pipes up to () without requiring certified welders.
Integrates advanced ultrasonic pulse-echo thickness measurement with specialized solid-state waveguides. The dual waveguides protect internal piezoelectric elements from extreme pipe wall temperatures ( to ).
Data is secured and routed using WirelessHART® protocols (IEEE 802.15.4), guaranteeing over 99% data reliability in dense metal refineries and chemical plants. Power is supplied by a field-replaceable Rosemount BP20E lithium module certified for intrinsically safe Class 1 Div 1 / Zone 0 hazardous locations.
