Product Overview

The 330880-28-15-048-00-02 is a Bently Nevada PROXPAC XL Proximity Transducer. It integrates a 3300 XL 8 mm probe with multiple approvals. This system delivers precise shaft displacement and vibration measurements for critical rotating machinery. Petro Auto Tech stocks this genuine unit for industrial automation needs.

Technical Specifications Analysis

This transducer uses 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. Deviation from best fit straight line (DSL) stays within ±0.025 mm (±1 mil). Frequency response covers 0 to 10 kHz with up to 305 metres of field wiring. The probe operates from -51 °C to +177 °C. Power requires -17.5 Vdc to -26 Vdc without barriers. The housing carries an IP66 rating verified by BASEEFA. Probe tip material is Polyphenylene Sulfide (PPS). Total system weight is 1.44 kg.

Application Scenarios & Usage Methods

Use the 330880-28-15-048-00-02 for radial vibration and axial position monitoring on steam turbines, compressors, and large pumps. Mount the probe with a 1.27 mm (50 mils) recommended gap setting. Connect using 3-conductor shielded triax cable up to 305 metres. The 3/4-14 NPT mounting thread simplifies installation into standard bearing housings. This transducer withstands harsh environments with its IP66-rated housing and wide temperature range.

Installation Guide & Packing List

Install the probe sleeve locknut to 39.3 N·m (350 in·lb) and retaining nut to 29.5 N·m (260 in·lb). Ensure the target shaft diameter is at least 50.8 mm. Use a flat target of minimum 15.2 mm diameter. The package includes the 330880-28-15-048-00-02 transducer with a 1-metre triaxial cable, two plugs, two washers, and mounting hardware. No fittings are included.

Purchasing Advice

Verify your system voltage matches the -17.5 Vdc to -26 Vdc requirement. Confirm the 48 mm probe penetration and 1.5-inch standoff adapter fit your machine geometry. Order from Petro Auto Tech for genuine Bently Nevada parts with reliable delivery.

Repair & Maintenance Tips

Inspect the probe cable and connector for damage before each use. Clean the probe tip with a soft cloth and isopropyl alcohol. Store the transducer in a dry, static-free environment between -51 °C and +177 °C. Avoid exposing the probe to temperatures below -34 °C to prevent pressure seal failure. Check housing and sleeve O-rings for wear annually.
