Bently Nevada 3300 XL 8 mm Probe – Model 330101-00-28-20-02-00

Key Technical Specifications

• Brand & Model: Bently Nevada 330101-00-28-20-02-00 – 3300 XL 8 mm probe without armor.
• Thread & Length Options: 3/8-24 UNF thread. Unthreaded length: 0.0 inch. Overall case length: 2.8 inches. Total length: 2.0 meters (6.6 feet).
• Connector Type: Miniature coaxial ClickLoc connector with standard cable (option 02).
• Nominal DC Resistance (RPROBE): 7.88 ± 0.50 Ω for the 2.0m probe length.
• Extension Cable Capacitance: 69.9 pF/m (21.3 pF/ft) typical.
• Linear Range: 2 mm (80 mils). Range begins at 0.25 mm (10 mils) from target, extends 0.25 to 2.3 mm (10 to 90 mils) → approx -1 to -17 Vdc.
• Recommended Gap for Radial Vibration: -9 Vdc (≈1.27 mm / 50 mils).
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ±5% (1.5m system) or ±6.5% (9m system) including interchangeability error at 0°C to +45°C.
• Deviation from Best Fit Straight Line (DSL): < ±0.025 mm (±1 mil) for standard 1.5m system; < ±0.038 mm (±1.5 mil) for 9m or extended range systems.
• Probe Tip Material: Polyphenylene sulfide (PPS) – thicker encapsulation for ruggedness.
• Probe Case Material: AISI 303 or 304 stainless steel (SST).
• Weight: 323 g/m (11.4 oz).
• Temperature Range (Standard Probe): -52°C to +177°C (-62°F to +350°F) operating/storage.
• Extended Temperature Range Probe: Tip -52°C to +218°C (-62°F to +425°F); Cable & connector -51°C to +260°C (-60°F to +500°F).
• Pressure Seal: Viton® O-ring seals differential pressure between tip and case. Contact custom design for pressure test requests.
• Relative Humidity: Less than 3% change in Average Scale Factor after 56 days at 93% RH per IEC 68-2-3.
• Field Wiring: 0.2 to 1.5 mm² (16-24 AWG). Recommend 3-conductor shielded triad cable. Max length 305 m (1000 ft) between Proximitor Sensor and monitor.

Robust Design & Environmental Tolerance

• The 330101-00-28-20-02-00 probe uses a patented TipLoc molding method. This creates a stronger bond between probe tip and body.
• CableLoc technology provides 330 N (75 lbf) pull strength. This securely attaches the probe cable to the tip.
• Optional FluidLoc cable prevents oil or liquid leakage through the cable interior.
• 8 mm probes give thicker PPS encapsulation of the probe coil. This makes the probe more rugged against physical abuse.
• Larger diameter probe body offers a stronger, more robust stainless steel case.
• Exposing the probe to temperatures below -34°C (-30°F) may cause premature pressure seal failure.

Frequently Asked Questions (FAQ)

• Q: What is the difference between standard and extended temperature range?
  A: Standard probe works -52°C to +177°C. Extended range probe tip withstands up to +218°C, and cable up to +260°C.
• Q: How long does delivery take?
  A: We dispatch within 5 days. Then FedEx/UPS/DHL shipping typically takes 3–7 business days.
• Q: Can I return this probe if it doesn't fit my application?
  A: Yes, we support 30-day returns for unused items in original packaging.
• Q: Does the probe include an extension cable?
  A: No, this model comes with a 2.0m cable and ClickLoc connector. Extension cables are ordered separately.
• Q: What linear range does this probe provide?
  A: It offers 2 mm (80 mils) linear range from 0.25 mm to 2.3 mm gap, output -1 to -17 Vdc.
• Q: Is the probe pressure tested before shipment?
  A: Standard units are not pressure tested. Contact our custom design department if your application requires a pressure seal test.
