The Bently Nevada 330708-00-10-50-12-05 is a high-performance 3300 XL series proximity probe designed for non-contact vibration and position sensing. Specifically, this model features an 11 mm diameter sensing element with a 5/8-18 UNF thread and comes without armor. What sets this variant apart is its FluidLoc cable option, which provides enhanced protection against fluid ingress in demanding environments. Therefore, this 3300 XL 11 mm probe is particularly well-suited for applications where oil, coolant, or other liquids may be present. The 5.0-meter total cable length offers flexibility for remote mounting configurations, while the ClickLoc connector ensures a secure and reliable electrical connection.
This section covers the essential technical parameters of the Bently Nevada 330708-00-10-50-12-05. First, the probe tip is constructed from polyphenylene sulfide (PPS), a material known for its excellent dimensional stability and chemical resistance. Meanwhile, the probe case uses AISI 304 stainless steel (SST), providing superior corrosion resistance and mechanical strength. The probe cable is a 75 Ω triaxial type with fluoroethylene propylene (FEP) insulation, ensuring signal integrity over long distances. Additionally, the 330708-00-10-50-12-05 includes the 5.0-meter (16.4 feet) cable length option, with the FluidLoc feature adding an extra layer of durability. For electrical performance, the DC resistance from the center conductor to the outer conductor (RPROBE) measures 7.2 ± 0.8 ohms. The agency approval option "05" confirms Multiple Approvals for international compliance.
The FluidLoc cable on this model represents a significant enhancement for challenging installations. Essentially, this cable design incorporates a specialized seal that prevents moisture and industrial fluids from migrating along the cable jacket. Consequently, it dramatically reduces the risk of signal degradation or probe failure in wet environments. Specifically, the FluidLoc option (designated by option "12") is highly recommended for machinery monitoring in paper mills, metal processing plants, and offshore applications. Furthermore, this feature complements the standard 75 Ω triaxial FEP cable construction, which already offers excellent electrical properties. Therefore, the 330708-00-10-50-12-05 delivers both superior signal quality and enhanced environmental protection.
The mechanical specifications of this sensor ensure reliable operation in tough conditions. For example, the 5/8-18 UNF probe case thread has a maximum length of thread engagement of 0.938 inches. When installing, the recommended torque for the probe case is 15.2 N•m (133 in•lb), with a maximum rated torque of 45.2 N•m (400 in•lb). Furthermore, the connector-to-connector torque should be finger tight, with a maximum of 0.565 N•m (5 in•lb). The minimum bend radius for the cable is 25.4 mm (1.0 inch), applicable with or without SST armor. Regarding environmental resilience, the operating and storage temperature range spans -51°C to +177°C (-60°F to +351°F). However, exposing this 3300 XL probe to temperatures below -34°C (30°F) may cause premature failure of the pressure seal. Additionally, the probe incorporates a Viton O-ring to seal differential pressure between the tip and the case.
Proper installation of the Bently Nevada 330708-00-10-50-12-05 maximizes its performance and service life. Initially, verify the thread engagement does not exceed 0.938 inches for the 5/8-18 UNF thread. Next, carefully route the 5.0-meter FEP cable while maintaining a bend radius above 25.4 mm to prevent cable damage. Specifically, for the FluidLoc cable, ensure the connector is fully seated and the sealing mechanism is properly engaged. When tightening the probe case, apply the recommended torque of 15.2 N•m to avoid mechanical stress. Additionally, tighten the ClickLoc connector to finger tightness plus the specified maximum torque. Meanwhile, protect the PPS probe tip from impact damage during handling. Since the probe is not pressure tested prior to shipment, consider contacting the custom design department if your application requires a pressure seal test.
