Detailed Product Information
🎯 Sensing Principle
The Bently Nevada 990-04-70-01-00 measures machinery parameters using precision sensing technology. Non-contact measurement eliminates mechanical wear, providing consistent data over years of continuous operation.
Applications
- Vibration Monitoring: Bearing housing and shaft vibration per ISO 10816.
- Position Measurement: Axial thrust, differential expansion, rod drop.
- Speed Reference: Keyphasor pulse for synchronous sampling.

Installation
- Mount rigidly — bracket resonance corrupts readings.
- Use manufacturer-specified cables only.
- Verify gap voltage/gain settings before commissioning.
- Secure connectors against vibration loosening.
📦 Shipping
24h handling. Ships with calibration data. 12-month warranty covering sensing element failure, calibration drift, connector damage.
❓ FAQ
Q: Calibration interval?
A: Annual verification recommended. Typical drift <0.5%/year.
Q: Cable length critical?
A: Yes — cable is part of calibrated system. Match original exactly.
💰 Spare Strategy
Sensors are wear items. Cable fatigue is #1 failure mode after 5-8 years. Keep one spare per measurement location on critical machines.
