Core Technical Specifications

• Brand & Model: Bently Nevada, 330101-48-71-20-02-CN (3300 XL Series 8 mm Probe).
• Linear Range: 2 mm (80 mils), effective from 0.25 mm to 2.3 mm (10 to 90 mils), corresponding to –1 to –17 Vdc output.
• Recommended Gap Voltage: –9 Vdc for radial vibration applications, approximately equal to 1.27 mm (50 mils) gap.
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% for 1 or 5 meter systems, including interchangeability error, tested from 0°C to +45°C.
• Deviation from Best Fit Straight Line (DSL): Less than ±0.025 mm (±1 mil) for standard 1 or 5 meter systems; less than ±0.038 mm (±1.5 mil) for 9 meter and ETR systems.
• Probe DC Resistance: 7.88 ±0.50 Ω from center conductor to outer conductor at 2.0 meter length.
• Extension Cable Capacitance: 69.9 pF/m (21.3 pF/ft) typical.
• Field Wiring Requirement: Use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. Maximum length is 305 meters (1000 feet).
• Probe Temperature Range: Standard probe operates from –52°C to +177°C (–62°F to +350°F). Extended temperature range probe tip withstands up to +218°C, with cable up to +260°C.
• Pressure Seal: Viton® O-ring seals differential pressure between the probe tip and case. Contact the custom design department if you require pressure testing.
• Relative Humidity Tolerance: Less than 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3.
• Probe Case Material: AISI 303 or 304 stainless steel (SST). Probe tip material is Polyphenylene sulfide (PPS).
• Weight: 323 g/m (11.4 oz).
• Connector Type: Miniature coaxial ClickLoc connector with standard cable (option code 02). Country Specific variant (CN).

Electrical Performance & System Compatibility

• Standard System Scale Factor: 7.87 V/mm ±5% (including interchangeability error) for 1 or 5 meter systems. 9 meter and ETR systems offer ±6.5% accuracy.
• Frequency Response & Field Wiring: Long field wiring up to 305 meters (1000 feet) introduces high-frequency signal roll-off. Refer to frequency response graphs (Figures 10 and 12) for attenuation details.
• System Compatibility: Use this probe only with 3300 XL series extension cables and Proximitor Sensors to maintain system accuracy.
• Noise Immunity: The coaxial construction provides excellent resistance to electrical noise in industrial environments.
• Environmental Durability: Humidity testing (93% relative humidity for 56 days) shows less than 3% gain drift, ensuring reliable performance in harsh conditions.

Frequently Asked Questions (FAQ)

• Q: Is this probe brand new and original?
  A: Yes, we supply brand new original Bently Nevada 330101-48-71-20-02-CN with factory standards.
• Q: Where does the linear range begin?
  A: The linear range starts at 0.25 mm (10 mils) from the target and extends to 2.3 mm (90 mils), with an output of –1 Vdc to –17 Vdc.
• Q: Can I use this probe in high-temperature applications?
  A: The standard probe tip withstands +177°C. For higher temperatures, select the extended temperature range version with tip up to +218°C and cable up to +260°C.
• Q: What is the stock and shipping status?
  A: We have units in stock. We ship within 5 business days via DHL, FedEx, or UPS for fast delivery.
• Q: Does the probe undergo pressure testing before shipment?
  A: Probes do not receive pressure testing before shipment, but they include a Viton® O-ring seal. Contact our custom design department if you require pressure seal testing.
• Q: What is the maximum field wiring length?
  A: You can run field wiring up to 305 meters (1000 feet) between the 3300 XL Proximitor Sensor and the monitor using shielded triad cable.
• Q: Can I return this product?
  A: Yes, we offer a 30-day return policy for products in original, unused condition with original packaging.
• Q: What is the difference between standard cable and FluidLoc cable?
  A: This model uses standard cable (option 02). FluidLoc cable (option 12) prevents oil or other liquids from leaking through the cable interior for applications with potential oil exposure.
