Description
BENTLY NEVADA 330780-50-00 3300 XL 11 mm Proximitor Sensor
1. Product Description
The BENTLY NEVADA 330780-50-00 is a non-contacting proximity sensor system designed for precise vibration, displacement, and speed measurements in rotating machinery such as turbines, compressors, and pumps. Part of the 3300 XL Series, this system includes an 11 mm probe, extension cable, and proximitor sensor, offering a longer linear range (2.54 mm) compared to standard 8 mm systems. It supports applications like axial position monitoring, phase reference (keyphasor) signals, and rod position measurements in reciprocating compressors. The system meets API 670 standards and is widely used in oil & gas, power generation, and manufacturing industries.

3. Advantages and Features
- Extended Linear Range: The 11 mm probe provides a 2.54 mm linear range, ideal for applications requiring larger measurement spans.
- Enhanced Stability: Improved temperature stability and RFI/EMI immunity ensure reliable performance in harsh environments.
- Easy Installation: Din-rail or panel-mount options and spring-loc terminals simplify wiring.
- Robust Design: Patented Tip Loc and Cable Loc technologies offer 330 N (75 lb) pull strength for the probe cable.
- API Compliance: Meets API 670 standards for critical machinery monitoring.
4. Application Areas and Case Studies
- Oil & Gas: Monitoring axial displacement in centrifugal compressors.
- Power Generation: Tracking turbine rotor expansion in thermal power plants.
- Manufacturing: Ensuring precise alignment of conveyor rollers in steel mills.
Case Study: A U.S. refinery reduced downtime by 20% using the 330780-50-00 to detect bearing misalignment in a critical pump, avoiding costly repairs.
5. Competitor Comparison
The 330780-50-00 outperforms standard proximity sensors by:
- Offering a 11 mm probe for extended linear range (vs. 8 mm in most alternatives).
- Supporting higher temperature operation (-35°C to +85°C vs. typical -20°C to +70°C).
- Including advanced EMI shielding for reliable performance in noisy industrial settings.
6. Selection Recommendations
- Probe Size: Choose 11 mm for applications needing larger measurement ranges; opt for 8 mm for compact spaces.
- System Length: Ensure the 5.0-meter cable matches installation requirements.
- Mounting: Select panel mount for easy access or din-rail for space-efficient setups.
7. Precautions
- Target Material: Use AISI 4140 steel targets for accurate measurements.
- Cable Integrity: Avoid exceeding the 330 N pull strength to prevent damage.
- Upgrades: Replace all components (probe, cable, proximitor) when migrating from legacy 7200-series systems.
