330904-00-10-70-02-05 3300 NSv Proximity Probe

330904-00-10-70-02-05 Bently Nevada 3300 NSv Proximity Probe

• Measurement linear range spans from 0.25 mm to 1.75 mm (10 to 70 mils). It begins at approximately 0.25 mm from the target.
• Incremental Scale Factor (ISF) equals 7.87 V/mm (200 mV/mil) with +12.5% / -20% interchangeability error across the full 1.5 mm range.
• Deviation from best-fit straight line (DSL) remains less than ±0.06 mm (±2.3 mils) ensuring high linearity.
• Frequency response covers 0 to 10 kHz (+0, -3 dB) typical with up to 305 meters of field wiring.
• Resolution is inherently limited by the system noise; the probe offers a stable analog output proportional to gap.
• Operating temperature ranges from -52°C to +177°C (-62°F to +351°F) for both operation and storage.
• Probe tip material uses Polyphenylene sulfide (PPS). The case is AISI 304 stainless steel (SST).
• Cable features 75 Ω coaxial FEP insulation, total length of 7.0 meters (23.0 feet) with a miniature coaxial ClickLoc connector.
• Minimum target size is 8.9 mm diameter; recommended minimum is 13 mm (0.5 in) diameter.
• Maximum torque on the M8x1 thread is 0.56 N•m (5 in•lb); finger-tight recommended.
• Minimum bend radius with or without armor is 25.4 mm (1.0 in).
• Probe DC resistance from center to outer conductor is 5.9 ± 0.9 ohms for the 7.0 m length.

Installation & Mechanical Specifications

• Thread engagement length for M8x1 case is 12 mm maximum.
• Recommended gap setting is 1.0 mm (40 mils) for optimal performance.
• Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) – three-conductor shielded triad cable is recommended.
• Maximum field wiring length between the 3300 XL NSv Proximitor and monitor is 305 meters (1000 feet).
• The probe seals differential pressure via a Viton O-ring; not pressure tested before shipment.
• Connector-to-connector torque for 1/4-28 or M8x1 cases: maximum 7.3 N•m (65 in•lb), recommended 5.1 N•m (45 in•lb).
• The probe and extension cable are mechanically and electrically compatible with the previous 3300 RAM series.

Environmental & Chemical Resistance

• Increased chemical resistance permits use in many process compressor applications.
• Superior side-view characteristics compared to the 3000-series 190 probe at the same gap distance.
• Storage and operating temperatures are identical: -52°C to +177°C.
• Agency approval option 05 covers multiple global certifications.

Electrical & Cable Data

• Extension cable DC resistance: center conductor 0.220 Ω/m (0.067 Ω/ft); shield 0.066 Ω/m (0.020 Ω/ft).
• Extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical.
• Probe cable type: 75 Ω coaxial FEP insulated, available in 0.5, 1, 5, or 7 meter total lengths.

Frequently Asked Questions (FAQ)

• Is this probe compatible with older 3300 RAM systems? Yes, mechanically and electrically interchangeable with previous 3300 RAM probes.
• What is the recommended target diameter for axial position measurement? Minimum 13 mm (0.5 in); smaller shafts may alter scale factor – reduce gap to compensate.
• Can I use this probe in high-pressure environments? The Viton O-ring seals differential pressure, but we do not pressure test before shipment. Contact custom design for test requirements.
• What is the maximum field wiring length? Up to 305 meters (1000 feet) between the Proximitor and monitor – see frequency response graphs for high-frequency rolloff.
• Do you have this item in stock? Yes, we maintain ready inventory for the 3300 NSv probe. Shipment occurs within 5 working days.
• What is the probe's DC resistance? For the 7.0 m length, RPROBE is 5.9 ± 0.9 ohms from center to outer conductor.
• What torque should I apply to the M8x1 thread? Finger tight is recommended; maximum 0.56 N•m (5 in•lb).
