The Bently Nevada 330708-00-10-50-01-05 belongs to the trusted 3300 XL series of proximity probes. Specifically, this model offers an 11 mm sensing diameter and a standard 5/8-18 UNF thread without armor. Consequently, it serves as a critical component for non-contact vibration and position monitoring in turbomachinery. This sensor reliably measures shaft displacement and identifies potential machine faults early. Therefore, plant engineers and maintenance teams frequently choose this 3300 XL 11 mm probe for its proven durability and accuracy. The overall length option of 1.0 inch and the 5.0-meter total cable length make it adaptable for various mounting configurations.
This section details the core technical parameters of the Bently Nevada 330708-00-10-50-01-05. First, the probe tip uses polyphenylene sulfide (PPS), providing excellent chemical resistance. Meanwhile, the probe case is manufactured from AISI 304 stainless steel (SST), ensuring structural integrity in harsh industrial environments. The probe cable is a 75 Ω triaxial type with fluoroethylene propylene (FEP) insulation. Additionally, this cable is available in total lengths of 1, 5, or 9 meters; the 330708-00-10-50-01-05 specifically includes the 5.0-meter (16.4 feet) option. For electrical characteristics, the DC resistance from the center conductor to the outer conductor (RPROBE) is 7.2 ± 0.8 ohms. The agency approval option "05" confirms it meets Multiple Approvals for global compliance.
The mechanical design of this sensor is robust and field-friendly. For instance, 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), while the maximum rated torque is 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, with or without SST armor, is 25.4 mm (1.0 inch). Regarding environmental resilience, the operating and storage temperature range is -51°C to +177°C (-60°F to +351°F). However, note that exposing this probe to temperatures below -34°C (30°F) may cause premature failure of the pressure seal. Moreover, the probe is designed to seal differential pressure between the tip and case using a Viton O-ring.
Proper installation ensures the 3300 XL 11 mm probe performs to its full potential. 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, ensuring the bend radius stays above 25.4 mm to prevent cable damage. Specifically, when tightening the probe case, apply the recommended torque of 15.2 N•m to avoid mechanical stress. Additionally, for the ClickLoc connector, tighten it only to finger tightness plus the specified maximum torque. Meanwhile, always handle the probe tip with care to protect the PPS material. Since the probe is not pressure tested prior to shipment, consider contacting the custom design department if your application requires a pressure seal test.
