Detailed Product Information
🎯 Measurement Principle
The Bently Nevada 176449-01 is an eddy-current proximity sensor system measuring shaft vibration and position without contact. A radio-frequency field at the probe tip changes impedance with gap distance, producing a linear voltage output (typically 200 mV/mil).
Applications
- Radial Vibration: X-Y probe pairs at each bearing for orbit analysis.
- Thrust Position: Axial probes monitor thrust bearing wear.
- Keyphasor: Once-per-rev reference for phase and speed.

Installation
- Set probe gap to mid-linear-range (typically -10 VDC for 200 mV/mil systems).
- Use only Bently Nevada extension cables — generic cable shifts calibration 10-15%.
- Finger-tighten connector plus 1/8 turn — over-tightening is the #1 installation error.
- System calibrated for AISI 4140 steel. Different materials need correction factors.
📦 Shipping & Warranty
24-hour handling. Includes calibration data sheet. 12-month warranty covering coil failure, connector damage, calibration drift.
❓ FAQ
Q: Recalibration interval?
A: Annual verification recommended. Typical drift less than 0.5%/year.
Q: Different cable length?
A: No — cable length is part of calibrated system. Must match original exactly.
Q: 5mm vs 8mm vs 11mm probe?
A: 5mm = 0.25mm range (small shafts). 8mm = 0.5mm (industry standard). 11mm = 1mm (large machines).
💰 Procurement
Proximitors are wear items — cable fatigue is the #1 failure mode after 5-8 years. Keep one spare per measurement location on critical machines.
