Bently Nevada 330106-05-30-50-12-05 3300 XL 8 mm Reverse Mount Probes
Product Introduction
This Bently Nevada probe delivers precise vibration and displacement readings on critical rotating machinery. The 330106-05-30-50-12-05 belongs to the widely used 3300 XL series. Its reverse mount design supports installation in compact machine housings. Additionally, the 8 mm probe tip uses polyphenylene sulfide for stable sensing. The stainless steel case resists corrosion and mechanical wear. The 5.0-meter cable carries a FluidLoc design for moisture protection. Moreover, this model holds CSA, ATEX, and IECEx approvals for hazardous areas. Therefore, it suits oil, gas, and petrochemical plants that require certified equipment.
Technical Specifications
The 330106-05-30-50-12-05 provides a nominal DC resistance of 8.73 Ω ± 0.50 Ω between center and outer conductors. The cable uses 75 Ω triaxial fluoroethylene propylene insulation. Specifically, the total length reaches 5.0 meters (16.4 feet). The connector option is a Miniature ClickLoc coaxial connector with FluidLoc cable (code 12). The agency approval option is 05 = CSA, ATEX, IECEx approvals. The probe case thread measures M10 x 1 with a maximum thread engagement of 15 mm. The probe tip material is polyphenylene sulfide (PPS). Meanwhile, the case material is AISI 303 or 304 stainless steel. The probe weighs 323 g/m (11.4 oz).
Mechanical and Environmental Parameters
The standard probe operates from -52°C to +177°C (-62°F to +350°F). However, exposure below -34°C (-30°F) may cause premature pressure seal failure. The probe seals differential pressure with a Viton O ring. Bently Nevada does not pressure test probes before shipment. Humidity testing shows less than 3% change in Average Scale Factor at 93% humidity for 56 days. The maximum tensile strength is 330 N from case to lead. Besides, the lead-to-connector joint holds 270 N. The connector uses gold-plated brass or gold-plated beryllium copper.
Installation Guide
First, confirm the M10x1 thread matches the machine housing. Next, position the probe so the tip sits at the correct gap. The reverse mount design allows access from the rear of the housing. Then, tighten the case to a maximum thread engagement of 15 mm. After that, connect the Miniature ClickLoc connector to the extension cable. Finally, route the cable away from hot surfaces and heavy vibration. Note that the FluidLoc option is often unnecessary on 330106 probes because the probe sleeve already provides protection. For instance, review your application carefully before ordering this cable type. In hazardous areas, follow all local wiring rules for approved equipment.
