Product Description
The Bently Nevada 330100-50-02 is a high-precision 3300 XL Proximitor Sensor for the 8 mm Proximity Transducer System. It converts the gap between a probe tip and a rotating shaft into a proportional voltage signal, forming the electronic core of the vibration monitoring loop.
This “50” configuration is calibrated for a 5.0-meter total system length (probe + extension cable). The -02 Agency Approval provides extensive global certifications for hazardous area installations, making it suitable for worldwide deployment.
Engineered for temperature stability and interchangeability, the sensor can be replaced in the field without recalibrating the system. It is critical for protecting high-speed rotating machinery such as turbines, compressors, and industrial motors.

Application Scenarios
The 330100-50-02 is used for critical machinery protection in hazardous zones, including:
-
Radial Vibration: Detecting shaft movement in bearings to identify imbalance or misalignment.
-
Axial Thrust Position: Monitoring longitudinal rotor movement to prevent internal contact.
-
Speed Monitoring: Providing pulses for tachometers and overspeed protection circuits.
-
Keyphasor Signals: Establishing a timing reference for phase-locked vibration analysis.
Frequently Asked Questions
Q: What is the difference between the -01 and -02 agency approvals?
A: Both provide hazardous area certifications, but the -02 option includes a broader range of international approvals beyond ATEX/IECEx/CSA, often covering additional regions (e.g., NEPSI), making it ideal for global spare parts management.
Q: Can I use this sensor with a 3300 XL 11 mm probe?
A: No. The 330100 series is specifically calibrated for 8 mm probes. Using an 11 mm probe will produce an incorrect scale factor, resulting in inaccurate vibration and position readings.
