Bently Nevada 330901-00-08-05-02-05 3300 NSv Proximity Probe

Description

0.0 in unthreaded length (Option 00) and 0.8 in case length (Option 08) define this 330901-00-08-05-02-05 configuration of the 3300 NSv proximity probe. As a critical component of the 3300 XL NSv Proximity Transducer System, this probe is specifically engineered for applications with limited installation space, such as machinery with small-bore bearings or restricted side-view and counter-bore areas. It provides precise radial vibration and axial position measurements in environments where standard 3300 XL 8 mm probes cannot be accommodated.

The system utilizes a 75 ohm coaxial cable and a Miniature ClickLoc connector (Option 02) to ensure signal integrity across the 0.5 m total length (Option 05). This unit is compatible with the 3300 XL NSv Proximitor Sensor and extension cable systems. With Agency Approval Option 05, this probe is suitable for use in hazardous areas requiring CSA, ATEX, and IECEx certifications.

Installation Guidelines

• Ensure the probe is installed with a gap setting appropriate for the 3300 NSv system (typically 1.0 mm or 40 mils from a 4140 steel target).
• Use recommended torque values: 5.1 N m (45 in lb) maximum for probe case; finger tight for initial positioning.
• Connectors should be kept clean and dry; utilize connector protectors if the connection is exposed to liquids or turbine oil.
• Ensure hazardous area installations follow local regulatory drawings for intrinsic safety or non-incendive wiring as specified by the product documentation.

Compliance and Certifications

• CSA / NRTL / C
• ATEX (Ex ia IIC, Ex nA IIC, Ex ec IIC)
• IECEx (Ex ia IIC, Ex nA IIC, Ex ec IIC)
• SIL 2 (HFT=0) / SIL 3 (HFT=1) Functional Safety
