Bently Nevada 330780-91-05 Proximitor Sensor
1. Overview
The Bently Nevada 330780-91-05 is an eddy-current proximity sensor system designed for non-contact measurement of vibration, position, and speed in rotating machinery.
It consists of a probe, extension cable, and Proximitor (signal conditioner) to form a complete monitoring solution.
2. Key Functions & Features
Eddy-Current Sensing Technology:
Generates a high-frequency (2MHz) electromagnetic field to detect conductive target displacement.
Measures both static position (e.g., shaft alignment) and dynamic vibration (e.g., bearing motion).
Signal Conditioning & Output:
Converts raw probe signals into a linear DC voltage (-2V to -18V) proportional to target distance.
Compatible with Bently Nevada 3500/System 1 for integration into machinery protection systems.
Robust Industrial Design:
Supports 5-meter (16.4 ft) or 9-meter (29.5 ft) system lengths with options for panel/rail mounting.
Meets API 670 standards for machinery protection in oil/gas/power industries.
3. Applications
Vibration Monitoring: Detects radial/axial vibration in turbines, compressors, and pumps.
Position Measurement: Tracks shaft displacement (e.g., thrust bearing wear).
Keyphasor® Signals: Provides speed/timing references for phase analysis.
4. System Components
Probe: 8mm diameter, detects target proximity.
Extension Cable: Connects probe to Proximitor (options: 3m–8.5m lengths, armored/standard).
Proximitor (330780-91-05): Conditions and amplifies the signal.
