Bently Nevada 3300 XL 8 mm Probe – Hazardous Area Approved Vibration Sensor

• Manufacturer: Bently Nevada – a leader in industrial machinery protection.
• Product Number: 330101-00-31-15-02-05 (with hazardous area certifications).
• Probe Type: 3300 XL 8 mm Probe, 3/8-24 UNF thread, without armor.
• Unthreaded Length Option: 00 = 0.0 inches (standard flush design).
• Overall Case Length: 31 = 3.1 inches – compact size for tight installations.
• Total Cable Length: 15 = 1.5 meters (4.9 feet) – standard system length.
• Connector Type: Miniature coaxial ClickLoc connector with standard cable for secure signal transmission.
• Approvals: 05 = CSA, ATEX, IECEx – safe for hazardous locations.

Core Technical Specifications & Linear Performance

• Linear Range: 2 mm (80 mils). The linear range begins at 0.25 mm (10 mils) from target and extends to 2.3 mm (10 to 90 mils). Output voltage spans approximately –1 to –17 Vdc.
• Recommended Gap for Radial Vibration: -9 Vdc [approximately 1.27 mm (50 mils)]. This setting ensures optimal sensitivity.
• Incremental Scale Factor (ISF): 7.87 V/mm (200 mV/mil) ± 5% for the 1.5 meter system. This includes interchangeability error from 0°C to +45°C (+32°F to +113°F).
• Deviation from Best Fit Straight Line (DSL): Less than ±0.025 mm (±1 mil) over the 80 mil range at standard temperatures.
• Nominal DC Resistance (RPROBE): 7.73 ± 0.50 Ω from center conductor to outer conductor (for 1.5m length).
• Extension Cable Capacitance: 69.9 pF/m (21.3 pF/ft) typical – maintains signal fidelity over distance.
• Field Wiring: Accepts 0.2 to 1.5 mm² (16 to 24 AWG). We recommend using 3-conductor shielded triad cable. Maximum length between Proximitor Sensor and monitor: 305 meters (1,000 feet).

Environmental Durability & Mechanical Strength

• Probe Tip Material: Molded Polyphenylene sulfide (PPS) – provides thicker encapsulation of the probe coil. This results in a more rugged probe.
• Probe Case Material: AISI 303 or 304 stainless steel (SST) – offers strong corrosion resistance and mechanical robustness.
• Standard Probe Temperature Range: -52°C to +177°C (-62°F to +350°F) for operating and storage.
• Extended Temperature Range Option: Probe tip supports -52°C to +218°C (-62°F to +425°F); cable and connector withstand -51°C to +260°C (-60°F to +500°F).
• Pressure Sealing: The probe seals differential pressure using a Viton® O-ring. Avoid temperatures below –34°C (–30°F) to prevent premature seal failure.
• Relative Humidity Performance: Less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity (IEC 68-2-3).
• FluidLoc Option: Prevents oil or liquid leakage through the cable interior (orderable separately).
