Bently Nevada 330105-02-12-10-02-00 3300 XL 8 mm Reverse Mount Probe

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330105-02-12-10-02-00 provides precise, reliable measurement. Part of the 3300 XL series, this 8 mm reverse mount probe is engineered for permanent installation in critical rotating assets. Its robust design reduces total cost of ownership by minimizing false trips and extending service intervals.

Technical Specifications

The 330105-02-12-10-02-00 features a probe tip made of polyphenylene sulfide (PPS), offering excellent chemical resistance and thermal stability. The probe case is constructed from AISI 303 or 304 stainless steel (SST), ensuring durability in harsh environments. The total length option -10 provides a 1.0 meter (3.3 feet) cable, while the connector option -02 uses a miniature ClickLoc coaxial connector for secure, quick connections. Nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.59 ± 0.50 Ω for a 1 meter probe length. The probe weighs 323 g/m (11.4 oz). Operating and storage temperature range for the standard probe is -52°C to +177°C (-62°F to +350°F). For extended temperature range probes, the tip withstands -52°C to +218°C (-62°F to +425°F), and the cable/connector handle -51°C to +260°C (-60°F to +500°F). Note: exposing the probe to temperatures below –34˚C (-30˚F) may cause premature failure of the pressure seal.

Cost-Effective Installation

Proper mounting maximizes probe life and reduces maintenance costs. The recommended probe case torque for reverse mount probes is 7.5 N•m (66 in•lbf), with a maximum rated torque of 22.6 N•m (200 in•lbf). Following these values prevents damage to the probe case and ensures consistent readings, avoiding costly rework.

Industry Applications

The 330105-02-12-10-02-00 excels in turbomachinery, compressors, and large pumps where continuous vibration monitoring is essential. Its PPS tip and stainless steel case withstand high temperatures and corrosive atmospheres, reducing replacement frequency. By catching bearing degradation early, operators avoid unplanned downtime and expensive repairs.

Maintenance & Reliability

Routine inspection of the probe cable and connector for wear prevents signal degradation. The miniature ClickLoc connector simplifies replacement without special tools. Choosing the 330105-02-12-10-02-00 means fewer spare parts and lower labor costs over the machine’s life.

Selection Guide

Before ordering, verify total length and connector options match your installation. The 330105-02-12-10-02-00 includes a 1.0 meter cable and miniature ClickLoc connector, with no agency approval option (-00).
