Bently Nevada 330710-00-05-50-02-05 3300 XL 11 mm Proximity Probe

Description

330710-00-05-50-02-05 specifies a 3300 XL 11 mm proximity probe equipped with M16 x 1.5 metric mounting threads, integrated stainless steel protective armor, 0 mm unthreaded length (Option 00), 50 mm overall case length (Option 05), a 5.0-meter total system length (Option 50), a miniature ClickLoc coaxial connector (Option 02), and multiple hazardous area approvals (Option 05).

This robust eddy-current proximity probe belongs to the Bently Nevada 3300 XL 11 mm Proximity Transducer System family. It is optimized for non-contact radial vibration and axial position measurements in high-stress industrial environments. By utilizing flexible stainless steel armor with an FEP outer jacket, this variant provides superior resistance to mechanical abuse, abrasives, and chemical environments compared to non-armored counterparts. The 5.0-meter integrated cable facilitates a direct connection to a compatible 5.0-meter 3300 XL 11 mm Proximitor Sensor, eliminating the need for an additional extension cable and reducing overall point-to-point connection resistance.

Features

• Metric M16 x 1.5 threaded case with flexible AISI 302 stainless steel armor and FEP outer jacket protects the triaxial cable from physical wear and environmental contamination.
• Option 00 specifies a 0 mm unthreaded length to ensure the entire case length can be threaded during housing or bracket installation.
• Option 05 designates a 50 mm overall case length, suitable for medium-depth mounting configurations in turbine bearing housings.
• Option 50 provides a 5.0-meter (16.4 feet) total probe cable length, enabling a direct link to the 5-meter Proximitor Sensor.
• Option 02 click-connection utilizes a gold-plated miniature coaxial ClickLoc plug for robust high-frequency transmission.
• Option 05 agency approval package certifies the transducer system for intrinsically safe and non-incendive environments.
• Polyphenylene sulfide (PPS) probe tip material withstands prolonged exposure to corrosive process lubricants and high temperatures.

Applications

• Axial shaft position and radial vibration monitoring on critical rotating machinery.
• Heavy-duty steam and gas turbine shaft monitoring under extreme conditions.
• Machinery protection in petrochemical plants, oil and gas extraction, and power generation facilities.
• Fluid-lubricated bearing and compressor monitoring requiring high-pressure tip sealing.

Connections and Interfaces

Gold-plated miniature male ClickLoc coaxial connector on the probe cable, providing a secure, low-impedance interface. Connects directly to a compatible 5.0-meter Proximitor Sensor.

Installation Guidelines

• M16 x 1.5 metric thread must be installed with a recommended torque of 21.1 N-m (187 in-lb) to prevent binding or over-torque damage. Do not exceed the maximum rated torque of 63.3 N-m (560 in-lb).
• Avoid exposing the probe to temperatures below -34 degC (-30 degF) to prevent premature failure of the Viton pressure seal.
• Ensure the minimum bend radius of the armored cable is at least 25.4 mm (1.0 in) during routing to prevent core conductor degradation.
• Shielding and grounding must comply with Bently Nevada drawing 141092 (intrinsically safe) or 140979 (non-incendive) as dictated by the area classification.

Compliance and Certifications

• Standards: EMC Directive 2014/30/EU, EN 61000-6-2 (Immunity), EN 61000-6-4 (Emissions), RoHS Directive 2011/65/EU.
• Functional Safety: SIL 2 (HFT=0), SIL 3 (HFT=1) certified when part of an approved safety system.
• Hazardous Area Approvals (Option 05): ATEX, IECEx, and CSA certified for Class I, Zone 0, Ex ia IIC T5...T1 Ga; Class I, Div 2, Groups A, B, C, D; Class I, Zone 2, Ex nA / Ex ec IIC Gc.
