Core Measurement Parameters

• Brand: Bently Nevada
• Model: 330101-00-67-20-02-CN (3300 XL Series)
• Linear Measuring Range: 2.0 mm (80 mils) from 0.25 to 2.3 mm from target.
• Recommended Gap for Vibration: Set at -9 Vdc, approximately 1.27 mm (50 mils).
• Sensitivity (Incremental Scale Factor): 7.87 V/mm (200 mV/mil) ±5% for standard 5m systems.
• Linearity (Deviation from Straight Line): Better than ±0.025 mm (±1 mil).
• Nominal Probe Resistance (RPROBE): 7.88 Ω ± 0.50 Ω for the 2.0m length.
• Cable Capacitance: 69.9 pF/m (21.3 pF/ft) typical for extension cable.

Robust Design & Construction

• Probe Tip Material: Molded Polyphenylene sulfide (PPS) with patented TipLoc for a stronger bond.
• Probe Case Material: AISI 303/304 Stainless Steel with 3/8-24 UNF thread.
• Cable Strength: Patented CableLoc design provides 330 N (75 lbf) pull-off resistance.
• Optional FluidLoc: Available to prevent fluid ingress along the cable interior.
• The 8mm diameter offers thicker encapsulation for superior physical ruggedness.

Environmental & Operational Limits

• Standard Temperature Range: Operates from -52°C to +177°C (-62°F to +350°F).
• Extended Temperature Range (ETR) Option: Probe tip up to +218°C (+425°F).
• Pressure Seal: Viton® O-ring seals differential pressure between tip and case.
• Humidity Resistance: Less than 3% ASF change at 93% relative humidity.
• Installation Torque: Recommended 11.2 N•m (100 in•lbf) for standard forward mounting.

Frequently Asked Questions (FAQ)

• Q: What is the key advantage of the 8mm probe design?
  A: The larger 8mm body and thicker tip encapsulation provide maximum robustness against physical damage.
• Q: Can this probe be used in high-pressure or wet environments?
  A: The standard Viton® seal handles differential pressure. For wet environments, order the optional FluidLoc cable.
• Q: How do I select the correct part number suffix for my application?
  A: Choose based on required cable length, connector type, and mounting dimensions using the suffix breakdown above.
• Q: Is this 330101-00-67-20-02-CN probe interchangeable with older 3300 series probes?
  A: Yes, but the 3300 XL series offers improved mechanical durability with TipLoc and CableLoc features.
