Bently Nevada 330910-06-25-50-11-00 | 3300 NSv Proximity Probes

Model Configuration & Ordering Details

Complete Part Number: 330910-06-25-50-11-00
Base Model: 330905 (3300 NSv Probe with M10X1 thread and armor)
Unthreaded Length: -06 = 60 mm (minimum 20 mm shorter than case length)
Case Length: -25 = 250 mm
Total Length: -50 = 5.0 meters (16.4 ft)
Connector/Cable: -11 = Miniature coaxial ClickLoc connector (with protector) + FluidLoc cable
Agency Approval: -00 (non-required)

Electrical Performance

DC Resistance: 5.3 ± 0.7 ohms (measured between center and outer conductors at 5.0m probe length).
Signal Consistency: The 75Ω coaxial cable with FEP insulation maintains 98% signal integrity at operating temperatures up to 177°C, minimizing data loss during critical measurements.

Mechanical Durability & Design

Material Specifications:
Tip: Polyphenylene sulfide (PPS) – withstands 260°C short-term exposure, with a compressive strength of 138 MPa.
Case: AISI 304 stainless steel – features a Vickers hardness of 200 HV, resisting corrosion in 3.5% salt spray for over 1,000 hours.
Cable: Available in 0.5m, 1m, 5m, or 7m lengths; the armored design supports 750N tensile load without deformation.

Installation Parameters:
Probe Case Torque: Max 33.9 N•m (300 in•lb); recommended 11.3 N•m (100 in•lb).
Connector Torque: Max 0.56 N•m (5 in•lb); finger-tight recommended for optimal connectivity.
Minimum Bend Radius: 25.4 mm (1.0 in) – tested to 10,000 flex cycles without cable damage.
Weight: 14-150g (0.5-5.3 oz) – lightweight yet robust for machinery integration.
