Technical highlights (engineered for reliability)

• Brand & series: Bently Nevada, 3300 XL 8 mm Proximity Probes – metric thread M10x1.
• Linear range: 2 mm (80 mils), starting at 0.25 mm from target. Output –1 to –17 Vdc.
• Recommended gap: –9 Vdc (approx. 1.27 mm / 50 mils) for radial vibration.
• DC resistance (RPROBE): 7.59 Ω ± 0.50 (1.0 m probe length).
• Tip material: Polyphenylene sulfide (PPS); case: AISI 303/304 SST.
• Temperature range (standard): –52 °C to +177 °C (–62 °F to +350 °F). Extended tip version withstands up to +218 °C.
• Sealing & humidity: Viton® O‑ring seals differential pressure. <3% ASF change after 56 days at 93% RH (IEC 68‑2‑3).

Field wiring & system integration

• Use 3‑conductor shielded triad cable, 0.2…1.5 mm² (16–24 AWG), tinned ends.
• Maximum extension between 3300 XL Proximitor Sensor and monitor: 305 m (1,000 ft).
• Frequency response graphs show signal roll‑off at high frequencies with longer wiring; refer to Figures 10 & 12 in manual.
• Intrinsically safe installations: Class I, Zone 0 (AEx/Ex ia IIC T5…T1 Ga) when used with zener barriers (drwg 141092) or galvanic isolators.

Installation essentials

• Thread engagement: Maximum 15 mm (M10x1). Probe weight 323 g/m (11.4 oz/ft).
• Pressure seal caution: 3300 XL 8 mm Probes use Viton® O‑ring; not pressure tested before shipment. Contact our custom design department if your application requires a pressure seal test.
• Temperature note: Exposing probe below –34 °C (–30 °F) may cause premature pressure seal failure.

Frequently asked questions

• Q: Can I use this probe with existing 3300 XL monitors?
  A: Yes, the 3300 XL 8 mm Proximity Probes are fully backward compatible with all 3300 XL Proximitor sensors.
• Q: What is the maximum cable extension without signal degradation?
  A: You can extend up to 305 meters (1000 feet) using recommended shielded triad cable. For high‑frequency response, consult the manual graphs.
• Q: Does the probe work in high‑humidity areas?
  A: Absolutely. It passes IEC 68‑2‑3 56‑day damp heat test with less than 3% Average Scale Factor change.
• Q: Which torque value should I use for the M10x1 thread?
  A: Bently Nevada recommends hand‑tight plus 1/8 turn maximum. Never exceed 15 mm thread engagement.
