Electrical Specifications & Performance

• Probe Resistance (RPROBE): 7.88 Ω ± 0.50 Ω for the 2.0m model.
• Cable Capacitance: Extension cable typical is 69.9 pF per meter (21.3 pF/ft).
• Linear Range: Provides a 2.0 mm (80 mil) linear measurement range.
• Recommended Gap: Set to -9 Vdc (approx. 1.27 mm / 50 mils) for radial vibration.
• Sensitivity (ISF): Standard system sensitivity is 7.87 V/mm (200 mV/mil) ±5%.
• Linearity (DSL): Deviation is less than ±0.025 mm (±1 mil) for standard systems.

Robust Mechanical Design

• Thread Type: Standard 3/8-24 UNF mounting thread.
• Probe Tip: Features a rugged Polyphenylene sulfide (PPS) molded tip.
• Probe Case: Constructed from AISI 303 or 304 stainless steel.
• Cable Strength: Patented CableLoc ensures 330 N (75 lbf) pull-off resistance.
• TipLoc Bonding: Patented molding creates a robust bond between tip and body.
• 8mm Advantage: Thicker encapsulation offers optimal robustness against physical damage.

Environmental Ratings & Operating Limits

• Standard Temperature: Operates from -52°C to +177°C (-62°F to +350°F).
• Extended Temperature: Option for tip up to +218°C (+425°F).
• Low-Temperature Note: Avoid below -34°C (-30°F) to prevent seal failure.
• Humidity Resistance: Less than 3% ASF change after 56 days at 93% humidity (IEC 68-2-3).
• Pressure Seal: Designed with a Viton® O-ring; not pressure tested before shipment.

Installation & Field Wiring Guidelines

• Field Wiring: Use 3-conductor shielded triad cable (16-24 AWG / 0.2-1.5 mm²).
• Wire Type: Tinned field wiring is recommended for better corrosion resistance.
• Maximum Distance: Up to 305 meters (1,000 feet) between probe and monitor.
• Signal Consideration: Long cable runs may affect high-frequency response; consult manual graphs.
• System Use: Compatible with standard 5, 1, and 9 meter system configurations.

Frequently Asked Questions (FAQ)

What does the "CN" suffix mean in the model number?

• The "CN" suffix indicates Country-Specific requirements. This often pertains to documentation, certifications (like a Certificate of Origin), or labeling needed for import into specific countries.

What is the difference between standard cable and FluidLoc cable?

• A standard cable is for general use. The FluidLoc option (code '12') has a special sealant to prevent oil from traveling inside the cable, which is critical for wet or oily machinery applications.

Why is an 8 mm probe recommended over smaller sizes?

• The 3300 XL 8 mm probe has a thicker plastic tip and a larger, stronger stainless steel case. This design provides much better physical durability and protection against accidental damage during operation and maintenance.

How do I set the correct gap for this probe?

• For measuring radial vibration, adjust the probe's position until the system output reads -9 Vdc. This voltage corresponds to a gap of approximately 1.27 mm (50 mils), which is the recommended setting.

Can this probe be used in high-humidity environments?

• Yes. Testing shows less than a 3% change in performance after 56 days in 93% relative humidity. This makes the Bently Nevada probe suitable for damp industrial conditions.
