3300 XL 8 mm Reverse-Mount Proximity Probe (5 m System)
Mechanical Construction – Extracted from Official Datasheet
• Probe Case: AISI 303 or 304 stainless steel, Ø 8 mm × 12 mm active tip
• Probe Tip Material: Polyphenylene sulfide (PPS) – chemically inert to turbine oils
• Thread: 3/8-24 UNF-2A reverse-mount – 22.6 N·m (200 in-lbf) max torque, 7.5 N·m (66 in-lbf) recommended
• Cable: 0.5 m integral, 75 Ω triaxial, FEP-insulated, 25.4 mm (1 in) minimum bend radius
• Connector: Gold-plated ClickLoc miniature coaxial – 0.565 N·m (5 in-lbf) max torque
Electrical Performance – API 670 4th Edition Verified
| Parameter | Value | |---|---| | Linear range | 2 mm (80 mil) |
| Sensitivity | 7.87 V/mm ± 5 % (200 mV/mil) |
| Frequency response | 0 Hz – 10 kHz (–3 dB) |
| Output impedance | 50 Ω (source) |
| Supply voltage | –17.5 Vdc to –26 Vdc (–24 Vdc nominal) |
| Current draw | 12 mA per probe (typical) |
| Operating temperature | –51 °C … +177 °C (probe/cable)
| Storage temperature | –60 °C … +177 °C
Installation & Field Considerations
• Reverse-mount cable exits away from shaft, eliminating radial clearance conflicts on steam-turbine bearings
• Not available with armor or connector protectors per factory spec
• Interchangeable with any 3300 XL 8 mm system—no bench calibration needed
