Bently Nevada 330106-05-30-05-02-05 Reverse Mount Probes

Bently Nevada 330106-05-30-05-02-05 3300 XL 8mm Reverse Mount Probe

Product Introduction

The Bently Nevada 330106-05-30-05-02-05 is a precision-engineered reverse mount probe from the 3300 XL 8 mm series. This probe features M10x1 threads and a compact 0.5-meter (1.6 feet) total length. It incorporates a miniature ClickLoc coaxial connector for secure, vibration-resistant connections. The probe tip uses robust Polyphenylene sulfide (PPS) material, while the case utilizes AISI 303 or 304 stainless steel. With CSA, ATEX, and IECEx approvals, this probe suits demanding turbomachinery monitoring applications in hazardous environments. Manufactured in the U.S.A., it delivers reliable, accurate measurements for critical asset protection.

Technical Specifications & Performance

The 330106-05-30-05-02-05 offers precise electrical characteristics for accurate proximity measurements. Its nominal DC resistance from center conductor to outer conductor measures 7.45 ± 0.50 Ω (highlighted in red) for the 0.5-meter length. This consistent resistance ensures reliable signal transmission between the probe tip and the Proximitor sensor. The probe cable uses 75 Ω triaxial FEP insulation, providing excellent shielding against electrical noise and interference. The system's linear range spans 1.5 mm (60 mils) with a recommended gap setting of 1.0 mm (40 mils), ensuring optimal measurement sensitivity for most turbomachinery applications.

Design Features and Construction

This 3300 XL 8 mm reverse mount probe incorporates several patented design features that enhance its reliability. The TipLoc molding method creates a robust bond between the probe tip and the probe body, preventing separation under mechanical stress. Additionally, the CableLoc design securely attaches the probe cable to the probe tip, providing 330 N (75 lbf) pull strength (highlighted in red) at the probe case to probe lead connection. The probe lead to extension cable connectors provide 270 N (60 lbf) pull strength (highlighted in red) . The probe case features M10x1 threads with a maximum thread engagement length of 15 mm. The miniature ClickLoc connector locks firmly into place, preventing loosening from vibration commonly found in rotating machinery.

Thread Configuration and Mounting

This probe features M10x1 metric threads, distinguishing it from the 3/8-24 UNF threaded variants. The M10x1 thread configuration suits installations requiring metric mounting standards, commonly found in European and Asian machinery. The maximum thread engagement length is 15 mm for optimal mounting stability. When installing this Bently Nevada 330106-05-30-05-02-05 , ensure the mounting hole accommodates the M10x1 thread specification. Proper thread engagement ensures accurate gap setting and prevents probe movement during operation. The reverse mount design allows installation from inside the machine casing, providing flexibility in tight spaces.

Agency Approvals and Certifications

This probe carries the "05" agency approval option, which includes CSA, ATEX, and IECEx approvals (highlighted in red) . These certifications confirm the probe's suitability for installation in potentially explosive atmospheres. The probe meets rigorous international standards for hazardous area equipment, providing peace of mind for safety-critical applications. For EPL Ga and Gc environments, the probe offers various temperature classifications from T1 through T5, accommodating ambient temperatures from -55°C up to +232°C depending on the classification. This flexibility makes the 330106-05-30-05-02-05 suitable for a wide range of global installations requiring hazardous area compliance.

Mechanical Properties and Temperature Range

The probe's material construction ensures durability in harsh industrial environments. The PPS probe tip offers excellent chemical resistance and dimensional stability at elevated temperatures. The AISI 303 or 304 stainless steel case provides corrosion resistance and mechanical strength. The standard probe operates across -52°C to +177°C (-62°F to +350°F) (highlighted in red) . For more demanding applications, an extended temperature range probe is available, supporting tip temperatures up to +218°C (+425°F). Note that exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe also withstands high humidity environments, with less than 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3.

Installation Guidelines

Installing the Bently Nevada 330106-05-30-05-02-05 requires attention to several important factors. First, always power down the system before making any connections. Next, ensure the mounting surface provides proper thread engagement for the M10x1 threads. The recommended maximum thread engagement length is 15 mm for optimal performance. Then, connect the miniature ClickLoc coaxial connector to the extension cable, ensuring it locks securely into place with an audible click. When routing the probe cable, avoid sharp bends and maintain adequate clearance from rotating parts. Finally, set the probe gap to the recommended value of 1.0 mm (40 mils) (highlighted in red) for optimal linearity. The Viton O-ring provides differential pressure sealing between the probe tip and case.
