Bently Nevada Probe 3300 Series Sensor 330904-00-05-70-01-05

Bently Nevada 3300 NSv Proximity Probe Technical Overview

Core Technical Specifications

• Measurement Range: The system provides a linear range of 1.5 mm (60 mils), operating from 0.25 mm to 1.75 mm from the target surface. We recommend a gap setting of 1.0 mm (40 mils) for optimal performance.
• Sensitivity and Accuracy: This 3300 NSv Probe delivers an Incremental Scale Factor of 7.87 V/mm (200 mV/mil) including interchangeability error. The Deviation from Best Fit Straight Line remains less than ±0.06 mm (±2.3 mils).
• Electrical Characteristics: The 7.0 meter probe length features a DC resistance of 5.9 ± 0.9 ohms between conductors. Extension cable specifications show center conductor resistance of 0.220 Ω/m and capacitance of 69.9 pF/m.
• Frequency Response: The system maintains 0 to 10 kHz response (+0, -3 dB typical) with up to 305 meters of field wiring between sensor and monitor.
• Environmental Tolerance: The probe operates from -52°C to +177°C with a PPS tip and AISI 304 stainless steel case for excellent durability.

Mechanical Installation Guidelines

• Mounting Configuration: The unit uses M8x1 probe case thread with maximum engagement length of 12 mm. Torque requirements specify finger tight installation with 0.56 N•m maximum for the tip.
• Wiring Specifications: Field wiring requires three-conductor shielded triad cable from 0.2 to 1.5 mm². You can extend wiring up to 305 meters to the monitor.
• Connector Details: The 330904-00-05-70-01-05 includes a miniature coaxial ClickLoc connector with connector protector for secure attachment.
• Mechanical Limits: Minimum bend radius is 25.4 mm (1.0 in) even with stainless steel armor. The probe seals differential pressure using a Viton O-ring.
