330880-28-40-058-01-02 | Bently Nevada PROXPAC XL Proximity Transducer - Petro Auto Tech

Product Overview

The 330880-28-40-058-01-02 is a Bently Nevada PROXPAC XL Proximity Transducer. This industrial-grade sensor measures shaft vibration and position in rotating machinery. It combines a rugged 8 mm probe with a durable housing, making it suitable for harsh environments. Petro Auto Tech offers this genuine part for reliable condition monitoring.

Technical Specifications Analysis

This transducer features a 2 mm (80 mils) linear range, starting at 0.25 mm from the target. Its Incremental Scale Factor (ISF) is 7.87 V/mm (200 mV/mil) ±5% over 0 °C to +45 °C. The frequency response covers 0 to 10 kHz with +0, -3 dB deviation. It requires -17.5 Vdc to -26 Vdc power without barriers, consuming 12 mA maximum. The probe operates from -51 °C to +177 °C. The housing carries an IP66 rating. Total system weight is 1.44 kg (3.2 lbm).

Application Scenarios & Usage Methods

Use the 330880-28-40-058-01-02 for vibration monitoring on steam turbines, compressors, and pumps. Install the probe within 1.27 mm (50 mils) recommended gap setting for optimal linear output. Connect via 3-conductor shielded triax cable up to 305 meters. The transducer works with Bently Nevada monitors for real-time protection.

Installation Guide & Packing List

Mount the probe using the 3/4-14 NPT fitting. Torque the retaining nut to 29.5 N·m and the probe sleeve locknut to 39.3 N·m. Ensure the target shaft diameter is at least 50.8 mm. The package includes the probe with 1-meter cable, one 3/4-14 NPT fitting, two plugs, and a standoff adapter (4-inch B dimension).

Purchasing Advice

Verify that your system requires a 58 mm probe penetration (C dimension). This model suits applications needing multiple approvals and IP66 protection. Petro Auto Tech stocks genuine Bently Nevada parts. Order the 330880-28-40-058-01-02 for reliable performance.

Repair & Maintenance Tips

Inspect the probe cable and connector for damage. Clean the probe tip with a soft cloth. Store in a dry environment within the -51 °C to +177 °C range. Check the housing O-ring and retaining chain periodically. Replace if the probe tensile strength exceeds 330 N.
