Bently Nevada 3300 XL 8 mm Probe – High-Reliability Vibration Sensor

• Manufacturer: Bently Nevada – a leader in machinery protection systems.
• Model Number: 330101-00-84-20-02-CN (country-specific configuration).
• Probe Type: 3300 XL 8 mm Probe, 3/8-24 UNF thread, without armor.
• Unthreaded Length: 0.0 inches (standard flush configuration).
• Overall Case Length: 8.4 inches – optimal for mounting in various casing designs.
• Total Cable Length: 2.0 meters (6.6 feet) – standard system length for proximity measurements.
• Connector Type: Miniature coaxial ClickLoc connector with standard cable for secure and quick installation.

Key Technical Specifications & Performance

• Linear Range: 2 mm (80 mils) – starts at 0.25 mm (10 mils) from target and extends to 2.3 mm (10 to 90 mils). Output voltage spans –1 to –17 Vdc.
• Recommended Gap for Radial Vibration: -9 Vdc [approximately 1.27 mm (50 mils)].
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ± 5% (for 2.0 meter system) including interchangeability error from 0°C to +45°C.
• Deviation from Best Fit Straight Line (DSL): Less than ±0.025 mm (±1 mil) across the linear range at standard temperatures.
• Nominal DC Resistance (RPROBE): 7.88 ± 0.50 Ω from center conductor to outer conductor.
• Extension Cable Capacitance: 69.9 pF/m (21.3 pF/ft) typical – ensures signal integrity over extended distances.
• Field Wiring Compatibility: Accepts 0.2 to 1.5 mm² (16 to 24 AWG). Use 3-conductor shielded triad cable. Maximum field wiring length: 305 meters (1,000 feet) between Proximitor Sensor and monitor.

Environmental & Mechanical Robustness

• Probe Tip Material: Molded Polyphenylene sulfide (PPS) – thicker encapsulation for superior coil protection.
• Probe Case Material: AISI 303 or 304 stainless steel (SST) – corrosion-resistant and durable.
• Operating Temperature (Standard Probe): -52°C to +177°C (-62°F to +350°F). Extended temperature range version supports up to +218°C at tip.
• Pressure Capability: Designed to seal differential pressure using a Viton® O-ring. Probes maintain integrity in pressurized environments.
• Relative Humidity Tolerance: Less than 3% change in Average Scale Factor after 56 days in 93% humidity (IEC 68-2-3).
• Pull Strength: 330 N (75 lbf) thanks to patented CableLoc design – securely attaches probe cable and tip.
• FluidLoc Option: Prevents oil or liquid leakage through cable interior (orderable for special applications).
