Features:

  • Links Machinery Vibration Monitoring Systems Through Miniature Coaxial ClickLoc Connector Technology
  • Provides Enhanced Chemical Resistance and Robust Non-Contact Displacement Measurement for Process Compressor Applications
  • Functions with Complete Mechanical and Electrical Interchangeability with Bently Nevada's Legacy 3300 RAM Proximity Probe Systems
The 330902-00-90-05-02-00 operates as the 3300 NSv Proximity Probe in a machinery protection system, providing accurate vibration monitoring and shaft position measurement for rotating equipment. It features a 1/4-28 UNF thread with armor, an unthreaded length of 0.0 inches, an overall case length of 9.0 inches, and a total length of 0.5 meter (20 inches). The 330902-00-90-05-02-00 continuously converts physical displacement into an electrical signal through its miniature coaxial ClickLoc connector and standard cable, distributing this signal to the monitoring system to support steady state operation of all connected monitors and modules. Seamless compatibility with existing 3300 RAM systems is standard with the 330902-00-90-05-02-00, however using the optional extension cable configuration will allow enhanced chemical resistance in process compressor environments where traditional probes would deteriorate. The 330902-00-90-05-02-00 has made improvements in several areas over previous probe designs in addition to incorporating superior side-view characteristics when gapped at the same distance from the probe target.

The 330902-00-90-05-02-00 provides essential proximity sensing functions common to the entire transducer system, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall machinery protection system. One 330902-00-90-05-02-00 probe is required per measurement point depending on the desired monitoring configuration. The 330902-00-90-05-02-00 occupies a standard probe mounting position and is always located at the designated measurement location on the machine casing.

For enhanced connection security applications, the 330902-00-90-05-02-00 requires proper connector protection at the probe-to-extension cable junction. In addition to standard signal transmission, the armored configuration also performs automatic strain relief. The 330902-00-90-05-02-00 executes cable retention using the patented CableLoc design specified in the probe construction. Using this method, the probe system continually secures the cable with 220 N (50 lb) of pull strength. If the system detects that the probe-to-extension cable connection will be exposed to adverse liquids, connector protectors will automatically seal the ClickLoc connectors and prevent most liquids from entering and adversely affecting the electrical signal.

The 330902-00-90-05-02-00 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).

General

  • Manufacturer Bently Nevada
  • Model 330902-00-90-05-02-00
  • Condition New Original ready stock
  • Product Family 330902-00-90-05-02-05,330902-00-90-05-02-CN
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Small Shaft Targets: Ideal for shafts smaller than 51 mm (2.0 in) where standard probes suffer from field distortion.
  • Centrifugal & Process Compressors: Widely used in centrifugal air compressors, refrigeration compressors, and process gas compressors.
  • Tight Clearances: Deployed in restricted cross-sections, such as small counterbores down to 13 mm (0.5 in), minimizing side-wall interference.
  • Axial Position Monitoring: Measures thrust on flat targets as small as 15 mm (0.6 in).
  • Radial Vibration Analysis: Captures real-time dynamic shaft motion to diagnose unbalance, misalignment, or bearing wear.
  • Thrust & Axial Displacement: Tracks slow-moving position shifts to prevent catastrophic rotor-to-stator contact.
  • Scale Factor Stability: Operates with a linear range of 1.5 mm (60 mils) and a standard scale factor of 7.87 V/mm (200 mV/mil) when observing AISI 4140 steel.
  • Signal Integrity: Built with gold-plated brass ClickLoc connectors to prevent connection loosening and eliminate signal noise.
  • Thread Fit: Ensure the 1/4-28 UNF threaded housing matches the machine casing tap.
  • Side Clearance: Maintain a minimum counterbore diameter or physical clearing around the tip to prevent the side-view effect from skewing the calibration.
  • Cross-Talk Avoidance: Maintain a minimum gap of 23 mm (0.9 in) between adjacent radial probe tips to prevent signal overlapping.
  • Field Wiring: Connect the Proximitor to the monitoring system (such as the Bently Nevada 3500 series) using a recommended 3-conductor shielded triad cable up to 305 metres (1,000 feet).
Description
The 330902-00-90-05-02-00 is a 3300 NSv Proximity Probe from Bently Nevada, featuring a 1/4-28 UNF thread with armor protection. The 330902-00-90-05-02-00 probe has an unthreaded length of 0.0 inches and an overall case length of 9.0 inches, with a total length of 0.5 meter (20 inches). The 330902-00-90-05-02-00 is equipped with a miniature coaxial ClickLoc connector and utilizes standard cable construction. Agency approval is not required for the 330902-00-90-05-02-00.

The 330902-00-90-05-02-00 and its corresponding extension cable are mechanically and electrically compatible and interchangeable with Bently Nevada's previous 3300 RAM proximity probe and extension cable. The 330902-00-90-05-02-00 offers increased chemical resistance compared to the 3300 RAM probe, which allows its use in many process compressor applications. The side-view characteristics of the 330902-00-90-05-02-00 are also superior to those of the 3000-series 190 probe when gapping the 330902-00-90-05-02-00 at the same distance from the probe target.

The 330902-00-90-05-02-00 comes in varying probe case configurations, including armored and unarmored 1/4-28, 3/8-24, M8X1 and M10X1 probe threads. All components of the transducer system for the 330902-00-90-05-02-00 have gold-plated brass ClickLoc connectors. ClickLoc connectors lock into place and prevent the connection from loosening. The patented TipLoc molding method provides a robust bond between the probe tip and the probe body of the 330902-00-90-05-02-00. Bently Nevada's patented CableLoc design provides 220 N (50 lb) of pull strength and securely attaches the probe cable to the probe tip of the 330902-00-90-05-02-00. Connector protectors are recommended for use on the probe-to-extension cable connection, as well as on the cable-to-Proximitor Sensor connection. Connector protectors prevent most liquids from entering into the ClickLoc connectors and adversely affecting the electrical signal.
