Key Technical Specifications

• Manufacturer & Brand: Bently Nevada – an industry leader in machine protection systems.
• Product Number: 330101-00-20-20-02-CN (3300 XL 8 mm Probe, without armor).
• Linear Range: Provides a 2 mm (80 mils) linear measurement range starting from 0.25 mm (10 mils) up to 2.3 mm (90 mils).
• Incremental Scale Factor (ISF): Delivers 7.87 V/mm (200 mV/mil) ±5% for standard 5 or 1 meter systems, ensuring interchangeability.
• Nominal Probe DC Resistance: Measures 7.88 ± 0.50 Ω between center and outer conductors at 2.0 meters length.
• Extension Cable Capacitance: Typical capacitance at 69.9 pF/m (21.3 pF/ft) maintains signal integrity.
• Recommended Gap Setting (Radial Vibration): Set at -9 Vdc which corresponds to approximately 1.27 mm (50 mils) from the target.
• Deviation from Best Fit Straight Line (DSL): Less than ±0.025 mm (±1 mil) for standard systems across 0°C to +45°C.
• Probe Tip Material: Molded Polyphenylene sulfide (PPS) for rugged encapsulation and TipLoc durability.
• Probe Case Material: AISI 303 or 304 stainless steel (SST) offers strong corrosion resistance.
• Temperature Range (Standard Probe): Operates and stores from -52°C to +177°C (-62°F to +350°F).
• Pressure Rating: Viton® O-ring seals differential pressure between probe tip and case; designed for reliable sealing.
• Relative Humidity: Less than 3% change in Average Scale Factor after 56 days of 93% humidity testing per IEC 68-2-3.
• Field Wiring: Accepts 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable; maximum length 305 meters (1000 feet).
• Thread Engagement Limit: Maximum thread engagement length for 3/8-24 UNF case thread is 0.563 inches.
• Probe Case Torque (Standard Forward Mount): Maximum rated torque at 33.9 N•m (300 in•lbf); recommended torque at 11.2 N•m (100 in•lbf).
• Probe Case Torque (First Three Threads): Maximum rated torque at 22.6 N•m (200 in•lbf); recommended torque at 7.5 N•m (66 in•lbf).

Enhanced Mechanical Features & Robustness

• Patented TipLoc™ Molding: Creates a stronger bond between the probe tip and the probe body, preventing internal loosening.
• CableLoc™ Design: Provides 330 N (75 lbf) pull strength for secure cable attachment, resisting industrial abuse.
• Thicker Coil Encapsulation: The 8 mm probe design uses thicker PPS plastic encapsulation, making the probe tip highly rugged.
• FluidLoc™ Cable Option: Available separately; prevents oil or liquid leakage through the cable interior (orderable when required).
• Larger Probe Body Diameter: Adds extra strength to the case, offering optimal physical protection in harsh environments.

Frequently Asked Questions (FAQ)

• Is this Bently Nevada 330101-00-20-20-02-CN probe brand new and original? – Yes, we guarantee brand new and original. All products come from authorized sources and are factory sealed.
• Do you have this 3300 XL 8 mm probe in stock? – Absolutely. We keep in stock inventory for fast shipment; the quantity updates in real time.
• How long will delivery take after purchase? – We process orders and ship within 5 days. Transit time depends on your location and selected courier (FedEx, UPS, or DHL).
• Can I return this probe if it does not fit my application? – We support 30-day returns from the delivery date. Please ensure the probe remains unused and in original packaging.
• What is the recommended gap setting for radial vibration monitoring? – Set the probe to achieve -9 Vdc output, equivalent to approximately 1.27 mm (50 mils) gap for best linear performance.
• What torque should I apply when mounting this probe? – Use recommended torque of 11.2 N•m (100 in•lbf) for standard forward mount; do not exceed 33.9 N•m maximum rating.
• Does this probe support the FluidLoc™ cable option? – The standard model 330101-00-20-20-02-CN does not include FluidLoc; you can order a variant with FluidLoc cable separately.
• What is the maximum field wiring length? – You can use up to 305 meters (1000 feet) of 3-conductor shielded triad cable between the Proximitor Sensor and the monitor.
• Is the probe temperature range suitable for high-heat turbines? – Standard probe operates up to +177°C; choose the extended temperature range probe for up to +218°C at the tip.
• How do I verify the resistance value? – Measure DC resistance between center and outer conductor; nominal value should be 7.88 ± 0.50 Ω at 2.0 meters length.
