Bently Nevada 330904 NSv Proximity Probe - 330904-00-25-05-02-CN

Bently Nevada 3300 NSv Proximity Probe Overview

Key Technical Specifications and Performance

• Measurement Range: The system offers a linear range of 1.5 mm (60 mils), starting from approximately 0.25 mm to 1.75 mm from the target.
• Sensitivity and Accuracy: It provides an Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil) with interchangeability error included. The Deviation from Best Fit Straight Line (DSL) is less than ±0.06 mm (±2.3 mils).
• Electrical Characteristics: The probe length of 0.5 meters features a DC resistance of 4.0 ± 0.5 ohms between conductors. We recommend a gap setting of 1.0 mm (40 mils) for optimal performance.
• Frequency Response: This 3300 NSv Probe maintains a typical frequency response of 0 to 10 kHz (+0, -3 dB) with up to 305 meters of field wiring.
• Environmental Tolerance: The probe operates in temperatures from -52°C to +177°C. It features a Polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case for excellent chemical resistance.

Installation and Mechanical Details

• Mounting Thread: It utilizes an M8x1 thread case with a maximum thread engagement length of 12 mm.
• Wiring Requirements: Field wiring requires a three-conductor shielded triad cable. You can run this cable up to 305 meters between the sensor and the monitor.
• Torque Specifications: You should tighten the probe finger tight, with a maximum torque of 0.56 N•m (5 in•lb) for the tip. The connector-to-connector torque should be 5.1 N•m (45 in•lb) recommended.
• Bending and Pressure: The 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.
