Application
-
Turbine Case Expansion Monitoring
Used in TSI systems to measure thermal growth of turbine casings during startup and operation. -
Power Generation Equipment Protection
Applied in steam and gas turbines to ensure safe thermal alignment and stable operation. -
Rotor-to-Stator Contact Prevention
Detects uneven thermal growth to prevent rubbing between rotating and stationary components. -
Mechanical Fault Detection
Identifies issues such as jammed or obstructed sliding feet on turbine casings for early maintenance action.
