Features:
- Compact 1/4-28 UNF threaded proximity probe without armor, with 0.8-inch overall case length for machines with tight installation constraints
- Miniature coaxial ClickLoc connector with connector protector and FluidLoc cable for secure signal transmission in harsh environments
- Multiple agency approvals supporting integration into the 3300 XL NSv Proximity Transducer System for small-target and restricted-clearance applications
The 330901-00-08-05-11-05 operates as the 3300 NSv Proximity Probe within the 3300 XL NSv Proximity Transducer System, providing accurate eddy-current displacement detection for vibration and position monitoring across all connected machinery channels. It continuously senses minute gap changes between the probe tip and the rotating or stationary target and transmits these signals through the 0.5-meter (20-inch) FluidLoc cable to the 3300 XL NSv Proximitor Sensor for signal conditioning. The 330901-00-08-05-11-05 mounts directly via its 1/4-28 UNF thread without armor, with 0.0-inch unthreaded length, 0.8-inch overall case length, and a total length of 0.5 meter (20 inches), distributing precise proximity data through the miniature coaxial ClickLoc connector to support steady-state operation of centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with severe physical restrictions. Direct target sensing is standard with the 330901-00-08-05-11-05; however, using the complete 3300 XL NSv Transducer System will allow accurate measurement in applications where counter bore, sideview, or rearview restrictions previously prevented the use of standard 5 mm or 8 mm probes. The 330901-00-08-05-11-05 has made improvements in several areas over previous transducer designs in addition to incorporating enhanced sideview and small-target capability within the 3300 family.
The 330901-00-08-05-11-05 provides essential sensing functions common to the entire 3300 XL NSv measurement chain, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall machinery protection system. One 330901-00-08-05-11-05 probe is required per measurement point depending on the desired monitoring coverage. The 330901-00-08-05-11-05 occupies only a compact sensing position at the machine housing and is always located at the target surface (the dedicated measurement point, the primary sensing location).
For small-target or restricted-clearance applications, the 3300 XL NSv Transducer System requires the 330901-00-08-05-11-05 probe installed at the measurement location. In addition to standard radial vibration and axial position measurements on conventional shaft sizes, the 330901-00-08-05-11-05 also performs reliable detection on shaft diameters smaller than 51 mm (2 inches) and flat targets smaller than 15 mm (0.6 inches). The 3300 XL NSv system executes precise gap measurement using the internal eddy-current circuitry specified in the 330901-00-08-05-11-05 design. Using this method, the transducer system continually monitors the proximity signal integrity. If the application presents counter bore, sideview, or rearview restrictions that prevent the use of standard Bently Nevada 3300 and 3300 XL 5 and 8 mm Transducer Systems, or if the target size falls below 51 mm (2 inches) for radial vibration or 15 mm (0.6 inches) for axial position, the 330901-00-08-05-11-05 will automatically provide the necessary detection capability and measurement accuracy while maintaining the average scale factor of 7.87 V/mm (200 mV/mil) across its 1.5 mm (60 mils) linear range, and place the validated signal in the monitoring system data path.
The 330901-00-08-05-11-05 Bently Nevada 3300 NSv Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
