Bently Nevada 330905-00-16-05-02-05 3300 XL NSv Proximity Probe

Description

The 330905-00-16-05-02-05 is a 3300 XL NSv proximity probe configuration featuring an M10x1 thread and non-armored design, optimized for tight installation environments. This specific unit is ordered with a 0.0 inch unthreaded length (Option 00), 1.6 inch case length (Option 16), and a 0.5 meter total system length (Option 05). It utilizes a standard miniature coaxial ClickLoc connector (Option 02) and includes multiple hazardous area approvals (Option 05).

As part of the 3300 XL NSv Proximity Transducer System, this probe is engineered for non-contact displacement measurement in machinery with restricted target areas, such as small-bore equipment, high-speed compressors, and aeroderivative turbines. It provides reliable radial vibration, axial position, and speed measurements on fluid-filmed bearing machines where standard 5 mm or 8 mm probes cannot fit due to side-view or counter-bore limitations. The system design ensures electrical and mechanical compatibility with 3300 NSv Proximitor sensors and extension cables, featuring the durable TipLoc and CableLoc designs for enhanced pull strength and connection security.

Features

Installation Guidelines

Ensure the probe is installed with the appropriate clearance to prevent physical contact with the rotating shaft. Use the recommended connector protectors (sold separately) on all probe-to-cable and cable-to-Proximitor connections to prevent moisture and liquid ingress. For hazardous area installations, adhere strictly to Bently Nevada installation drawings for intrinsic safety (Ex ia) or non-incendive (nA, ec) protection methods as indicated by the approval ratings.
