Bently Nevada 330104-00-09-50-02-05 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330104-00-09-50-02-05 is a 3300 XL 8 mm proximity probe designed for precise, non-contact vibration and position measurement in critical rotating machinery. This probe uses a polyphenylene sulfide (PPS) tip and an AISI 303 or 304 stainless steel case for durability in harsh environments. With M10 x 1 thread and armor protection, it suits demanding industrial applications. The probe includes a miniature coaxial ClickLoc connector and standard cable, with a total length of 5.0 meters (16.4 feet). It carries CSA, ATEX, and IECEx approvals, making it suitable for hazardous area installations.

Technical Specifications

The 330104-00-09-50-02-05 operates with a nominal probe DC resistance of 8.73 ± 0.50 Ω from center conductor to outer conductor at 5.0 m length. It requires a power supply of -17.5 Vdc to -26 Vdc (or -23 Vdc to -26 Vdc with barriers) and draws a maximum of 12 mA. The output resistance is 50 Ω, and sensitivity is less than 2 mV change per volt change in input voltage. The probe is designed to seal differential pressure between tip and case using a Viton O-ring. Temperature classifications range from T1 to T5 for EPL Ga and Gc, with ambient temperatures from -55°C to +232°C depending on rating. For EPL Dc, surface temperature limits vary with ambient conditions.

Industry Applications

This proximity probe excels in monitoring vibration and shaft position in turbines, compressors, pumps, and motors. Its CSA, ATEX, and IECEx approvals allow use in Class I, Zone 0 and Zone 2 hazardous areas, including Groups A, B, C, D, E, F, and G. The 8 mm sensor size provides reliable measurements in tight spaces, while the armored construction resists mechanical damage. Typical applications include steam turbine bearing vibration monitoring, centrifugal compressor shaft displacement, and pump health assessment in oil and gas, power generation, and chemical processing facilities.

Installation & Setup Guidance

Install the 330104-00-09-50-02-05 with a 3300 XL 8 mm Proximitor Sensor and extension cable per manufacturer guidelines. For intrinsically safe installations, use approved zener barriers per drawing 141092. For nonincendive circuits, connect per drawing 140979. Ensure proper gap at 1.27 mm (50 mils) using an AISI 4140 steel target for calibration. The probe thread is M10 x 1; use appropriate mounting hardware. Verify the cable routing avoids sharp bends and excessive strain. Always follow local electrical codes and safety regulations.

Maintenance & Reliability

Regular inspection of the probe tip and cable for wear or damage helps maintain measurement accuracy. The PPS tip resists many chemicals, but avoid abrasive contact. The Viton O-ring provides reliable sealing; check for signs of degradation in high-temperature or corrosive environments. For safety-rated systems, follow the manufacturer's safety manual for periodic testing. The 3300 XL series is known for long-term stability, reducing the need for frequent recalibration. Proper installation and environmental control extend service life.

Selection Guide & Purchasing Advice

When ordering the 330104-00-09-50-02-05, verify the total length option (5.0 meters) and connector type (miniature coaxial ClickLoc) meet your system requirements. Confirm the agency approval option (CSA, ATEX, IECEx) matches your area classification. This probe is part of the 3300 XL 8 mm family and requires compatible Proximitor sensors and extension cables.
