Product Overview — Quick Pyramid Summary
The 330191-40-75-50-00 Bently Nevada proximity probe delivers rugged performance for shaft position sensing in industrial equipment.
Key Technical Highlights
- The 330191-40-75-50-00 probe uses an 8mm 3300 XL tip for maximum mechanical strength.
- Power supply range: -17.5 Vdc to -26 Vdc for linear operation.
- Sensitivity: Less than 2 mV change per volt input variation.
- Probe DC resistance: 8.73 Ω ±0.50 for 5-meter length.
- Standard cable: 75Ω triaxial FEP insulated (optional PFA for high temperature).
- Probe tip: Polyphenylene sulfide (PPS) with AISI 303/304 stainless steel case.
- Connector material: Gold-plated brass or beryllium copper.
- Output resistance: 50Ω; typical current draw 12 mA max.
Measurement & Environmental Capabilities
- Accurate shaft position measurement using eddy-current sensing with 8mm encapsulated tip.
- Operational classifications: T1–T5 based on ambient temperature.
- Ambient range: -55°C to +232°C (T1), maintaining stability across rated classes.
- Compatibility ensured when paired with BN extension cables and Proximitor sensors.
Mechanical & Cable Features
- Patented TipLoc molding provides strong tip-to-body bonding.
- CableLoc design enhances pull strength to 330 N between probe and cable.
- Optional armor: flexible AISI 302/304 stainless steel with FEP jacket.
- Maximum connector torque: 0.565 N·m (5 in·lbf).
Installation Guidelines
- Thread size: 3/8-24 UNF with 0.563 inch maximum thread engagement.
- Seal the tip using Viton O-ring for differential pressure sealing.
- Avoid overtightening connectors beyond 0.565 N·m to protect terminals.
- Follow installation drawing 140979 for wiring and grounding standards.
Packaging & Shipping
- Includes one 330191-40-75-50-00 probe with protective cover and mounting guide.
- Packed in shockproof foam with connector cap and spare Viton seal.
- Global delivery via FedEx, UPS, or DHL.
