330104-03-12-10-02-00 Bently Nevada 3300 XL 8 mm Metric Reverse Mount Probe

Technical Overview

The Bently Nevada 330104-03-12-10-02-00 belongs to the 3300 XL 8 mm series, the industry standard for machinery protection and condition monitoring. This probe effectively tracks radial vibration, axial position, and speed in high-speed industrial assets such as gas turbines, steam turbines, and large-scale centrifugal compressors. By utilizing advanced eddy current technology, the sensor detects minute movements in a conductive target material without making physical contact, ensuring zero wear on the monitored shaft.

This specific configuration excels in high-temperature and high-pressure environments, maintaining stable performance in the presence of steam, oil, and corrosive process gases. Furthermore, the probe features a reverse-mount design with a metric thread, allowing for flexible installation in various machine casings. Its tight linearity and improved temperature stability provide plant operators with deterministic data, which is crucial for preventing catastrophic machinery failure and optimizing maintenance schedules.

Key Technical Characteristics

• Superior Linearity: The probe delivers a highly linear output across its full measurement range, which enhances the accuracy of diagnostic data for turbomachinery.
• Environmental Resilience: Constructed with a polyphenylene sulfide (PPS) tip and a stainless steel body, the unit resists chemical corrosion and moisture ingress.
• Interchangeability: This 3300 XL probe remains fully backward compatible with older 3300 series Proximitor sensors, simplifying the upgrade path for existing monitoring systems.
• Low Signal-to-Noise Ratio: Optimized electrical shielding rejects Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), ensuring a clean signal for the 3500 Monitoring System.
• Mechanical Protection: The 1.0-meter probe cable includes integrated stainless steel armor to prevent physical damage during installation and long-term operation.
