3300 XL 8 mm Armored Probe – “Long-Nose” for Deep Bores
Signature Geometry
330102-36-80-10-02-05 = 3.6″ (91 mm) case + 8.0″ (203 mm) total “long-nose” body, armored.
This length is the sweet spot for reaching the center of large-bore steam-turbine casings without extra extension cables.

Three Real-World Installations
• Frame 9E gas turbine compressor inlet guide vane – probe nose protrudes 50 mm past labyrinth seal, capturing surge-frequency blade flutter at 8.3 kHz.
• Hydro-pump labyrinth seal – armored body resists 1 g vibration without conduit.
• Refinery FCCU regenerator blower – long body avoids hot coking deposits on cable.
Quick-Check Compatibility
Works with any 3300 XL 8 mm system: 330180-50-05/-51-05 proximitors, 330130-XXX extension cables.
Drop-in replacement for legacy 7200-series “long-tip” probes – no recalibration required.
