Bently Nevada 330904-00-25-05-02-05 3300 XL NSv Proximity Probe

Description

330904-00-25-05-02-05: 3300 XL NSv proximity probe, M8x1 thread, with stainless steel armor (Option 00 unthreaded length, Option 25 case length, Option 05 total length, Option 02 standard cable, Option 05 multiple approvals). This transducer is part of the 3300 XL NSv Proximity Transducer System, specifically designed for machinery with limited installation space, such as small-bore rotating equipment, centrifugal air compressors, and refrigeration compressors.

The system excels in precision measurements where standard 3300 or 3300 XL 5 mm and 8 mm probes are restricted by counterbore or side-view limitations. With its M8x1 threaded probe body and integrated stainless steel armor, this configuration provides both mechanical protection and high-resolution displacement sensing for radial vibration and axial position monitoring on shafts smaller than 51 mm (2 in).

Features

• M8x1 thread probe body with stainless steel armor (Option 00 unthreaded, 25 case length)
• 0.5 meter (20 in) system length (Option 05)
• Miniature coaxial ClickLoc connector, standard cable (Option 02)
• Multiple agency approvals (Option 05) for hazardous area operation
• Compatible with 3300 XL NSv Proximitor Sensor and extension cables
• Reduced target area requirement suitable for small-bore machinery

Applications

• Small-bore fluid-filmed bearing machines
• Centrifugal air and process gas compressors
• Refrigeration compressor monitoring
• High-speed equipment with limited target geometry
• Axial (thrust) position and radial vibration measurements
• Tachometer and zero-speed sensing

Installation Guidelines

• Ensure the Proximitor Sensor is installed in a protected area, providing a degree of protection of at least IP54.
• Observe torque specifications: maximum 5.1 Nm (45 in-lb) for probe case tightening.
• Maintain a minimum bend radius of 25.4 mm (1.0 in) for cable routing.
• Use appropriate thread engagement lengths (max 12 mm for M8x1 probes) to prevent binding during installation.
• Refer to Bently Nevada drawing 141092 for intrinsically safe (ia) installations and 140979 for non-incendive (nA, ec) installations.
