Bently Nevada 3300 NSv Proximity Probe – Model 330904-08-10-70-12-05

Physical Design & Construction

The probe is built to withstand harsh industrial environments and repeated mechanical stress.

• Probe Diameter: Compact 4.8 mm design for easy installation.
• Cable Diameter: Outer jacket measures 5.3 mm for added durability.
• Total Weight: Lightweight at only 52 grams (probe and cable combined).
• Armor Protection: Features a 0.9 mm thick stainless steel armored sleeve.
• Flexibility & Life: Minimum bend radius of 25.4 mm ensures over 200,000 bend cycles.
• Sealing Reliability: O-ring seal withstands at least 1000 pressure cycles at 5 bar.

Electrical Specifications & Measurement Performance

Engineered for accurate signal transmission and wide frequency response in monitoring systems.

• Probe Resistance: Measures 5.9 Ω ±0.9 Ω at the full 7.0 meter cable length.
• Cable Resistance: Center conductor: 0.220 Ω/m, Shield: 0.066 Ω/m.
• Cable Capacitance: Consistent low capacitance of 69.9 pF per meter.
• Frequency Response: Flat from 0 to 10 kHz (±3 dB) even with 305 m of wiring.
• EMI/RFI Immunity: High immunity, tolerates ≥25 V/m from 80 to 1000 MHz.
• Linear Measurement Range: Wide range from 0.25 to 1.75 mm (10 to 70 mils).
• Scale Factor (Sensitivity): 7.87 V/mm with a ±20% tolerance.
• Optimal Setup Gap: For best linearity, set the gap to 1.0 mm (40 mils).
