Bently Nevada 330104-00-07-50-02-00 3300 XL 8 mm Proximity Probe

Product Overview

When unplanned downtime threatens production targets, the Bently Nevada 330104-00-07-50-02-00 3300 XL 8 mm proximity probe delivers precise shaft displacement and vibration measurements. This metric probe, part of the trusted 3300 XL series, features a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case for durability in harsh environments. With a 5.0-meter cable and M10x1 thread, it integrates seamlessly into existing monitoring systems. Choosing this probe reduces total cost of ownership by minimizing false trips and extending maintenance intervals.

Technical Specifications

The 330104-00-07-50-02-00 offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, roughly 1.27 mm (50 mils). Operating temperature spans -52°C to +177°C (-62°F to +350°F), with an extended range option for probe tips up to +218°C. Nominal DC resistance (RPROBE) is 8.73 ± 0.50 ohms for the 5.0-meter length. These parameters ensure consistent performance, reducing calibration costs and improving measurement accuracy over the equipment lifespan.

Industry Applications

This proximity probe excels in turbomachinery, compressors, and large pumps where real-time vibration monitoring is critical. In a refinery, for example, the 330104-00-07-50-02-00 provides early detection of shaft misalignment, preventing costly catastrophic failures. Its robust PPS tip and stainless steel case withstand high temperatures and corrosive atmospheres, lowering replacement frequency and associated labor expenses. By integrating this probe, facilities achieve higher uptime and more predictable maintenance budgets.

Installation & Setup Guidance

Proper installation maximizes the probe's value. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable. Maximum field wiring length between the Proximitor sensor and monitor is 305 meters (1,000 feet). For radial vibration, set the gap to -9 Vdc (approximately 1.27 mm). The M10x1 thread allows secure mounting with a maximum thread engagement of 15 mm. Correct installation reduces commissioning time and avoids costly rework.

Maintenance & Reliability

The 330104-00-07-50-02-00 probe requires minimal routine care. Its PPS tip resists wear, and the stainless steel case prevents corrosion in most industrial environments. The probe seals differential pressure using a Viton O-ring; avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature seal failure. Regular inspection of the cable and connector ensures signal integrity. This low-maintenance design translates to lower lifecycle costs and fewer unscheduled shutdowns.

Compatibility & Integration

This 5-meter probe is designed for use with the 5-meter Proximitor sensor only. It supports intrinsically safe installations when paired with approved zener barriers per drawing 141092 or galvanic isolators, achieving Class I, Zone 0 ratings. For non-incendive circuits, use drawing 140979. This compatibility simplifies system design and reduces integration risk, saving engineering time and procurement costs.
