- Full System Interchangeability: Interchangeable within 3300 XL 8mm ETR system
Application Scenarios
- Very thick-walled bearing housings: Monitors shaft vibration through extremely thick bearing caps
- Large steam turbine casings: Measures shaft position through thick high-pressure turbine casings
- Heavy-duty compressor cylinders: Monitors piston rod position through thick compressor cylinder walls
- Large hydro turbine housings: Measures shaft vibration through thick concrete and steel housings
- Nuclear reactor coolant pumps: Monitors shaft vibration through thick pressure boundary walls
- Large diesel engine blocks: Measures crankshaft vibration through thick engine block castings
- Heavy forging presses: Monitors ram position through thick press frames
- Large marine propulsion shafts: Measures shaft vibration through thick stern tube castings
Performance Parameters Identical electrical performance to other 3300 XL 8mm ETR probes. The very long case provides excellent heat conduction from the probe tip to the mounting structure, which can be advantageous in high-temperature applications. The 25mm case length provides substantial mass for vibration damping.
Material Composition Identical to other 3300 XL 8mm ETR probes. The 25mm case provides additional stainless steel mass.
Structural Characteristics Cylindrical stainless steel case with M10x1 thread and 19mm smooth unthreaded section. The 25mm overall length provides 6mm of threaded section plus 19mm of unthreaded section. This is the longest standard case length in the 3
