Product Overview

The 330880-28-15-051-00-02 is a Bently Nevada PROXPAC XL Proximity Transducer. This industrial automation component measures shaft vibration and position in rotating machinery. It integrates a 3300 XL 8 mm probe with multiple approvals, making it a trusted choice for critical asset protection.

Technical Specifications Analysis

This transducer operates with a power supply of -17.5 Vdc to -26 Vdc without barriers, and -23 Vdc to -26 Vdc with barriers. It delivers a linear range of 2 mm (80 mils) and an Incremental Scale Factor (ISF) of 7.87 V/mm (200 mV/mil) ±5%. The frequency response spans 0 to 10 kHz with +0, -3 dB. The probe temperature range is -51 °C to +177 °C, and the housing carries an IP66 rating. The total system weight is 1.44 kg.

Application Scenarios & Usage Methods

Use this transducer for real-time vibration monitoring on steam turbines, centrifugal compressors, and large pumps. Mount the probe with a 3/4-14 NPT thread and set the recommended gap at 1.27 mm (50 mils). Connect using 3-conductor shielded triax cable up to 305 metres. The 8 mm probe tip, made of Polyphenylene Sulfide (PPS), withstands harsh environments.

Installation Guide & Packing List

Install the probe sleeve locknut with 39.3 N·m torque. Ensure the target shaft diameter is at least 50.8 mm. Use the provided two plugs and two washers for fittings. The package includes the PROXPAC XL transducer assembly with probe, cable, and connectors. No additional certificates or warranty documents are included.

Purchasing Advice

Verify your system voltage matches the -17.5 Vdc to -26 Vdc range. Choose this model if you need IP66 protection and a 1.5-inch standoff adapter. Petro Auto Tech stocks genuine Bently Nevada parts with fast delivery. Order the 330880-28-15-051-00-02 for reliable machine protection.

Repair & Maintenance Tips

Inspect the probe cable for cuts or abrasions. Clean the probe tip with a soft cloth and avoid solvents. Store the transducer in a dry environment within -51 °C to +177 °C. Check the retaining nut torque at 29.5 N·m periodically. Replace the sleeve O-ring if damaged.
