Bently Nevada BA21504-000-032-10-02 Standard Mount Proximity Probe

Description

For precision machinery monitoring and displacement analysis, the Bently Nevada BA21504-000-032-10-02 proximity probe provides reliable eddy current measurement capabilities in industrial turbomachinery. This standard mount probe is designed to measure static and dynamic shaft displacement, vibration, and speed, serving as a critical hardware element in predictive maintenance and machinery protection systems. It features a robust physical build optimized for survivability in harsh, oil-lubricated turbine and compressor environments.

The mechanical configuration of this model includes a standard 3/8-24 thread design with an overall case length of 32 mm and a completely threaded body (0.0 inches unthreaded length). With a 1.0-meter total system length and a miniature male coaxial connector, it integrates directly with standard Bently Nevada proximity transducer systems and extension cables. This model is equivalent to and replaces the standard 21504-000-032-10-02 part number.

Features

• Standard Mount Design: Built with a standard 3/8-24 UNF-2A thread configuration for stable, secure industrial installation.
• Fully Threaded Case: 0.0 inches of unthreaded length ensures maximum mounting flexibility within standard brackets.
• Rugged Case Architecture: Features a 32 mm overall case length optimized for tight-clearance installation paths.
• Reliable Termination: Terminated with a high-integrity miniature male coaxial connector to prevent signal attenuation and moisture ingress.
• Physical Tolerances: Formulated with a total length tolerance of +0.25 meters / -0.10 meters to simplify field routing.

Applications

• Steam turbine rotor and shaft vibration monitoring
• Centrifugal and axial compressor displacement measurements
• Hydroelectric generator shaft alignment tracking
• High-speed industrial gearbox thrust and radial movement detection
• Industrial pump and motor speed and phase reference monitoring (Keyphasor)

Installation Guidelines

To ensure accurate calibration and prevent physical damage during operation, adhere to the following installation parameters:

• Probe Clearance: Maintain a minimum lateral clearance from adjacent structural metals to avoid cross-talk or target distortion.
• Cable Routing: Observe the minimum bend radius constraints for the 1.0-meter coaxial cable to prevent internal conductor damage. Do not route coaxial cables parallel to high-voltage AC power lines.
• Thread Engagement: Use a calibrated torque wrench to tighten the 3/8-24 threads, ensuring the probe body is secured without distorting the internal sensor coil assembly.
