Features:

  • Reverse Mount for Restricted Access
  • Extreme Temperature Operation
  • FluidLoc Cable for Liquid Protection
The Bently Nevada 330907-05-30-10-12 features a reverse mount design with M10X1 metric threads, allowing installation in machinery where standard probe mounting is impossible due to rear-view or side-view clearance limitations. This configuration is specifically engineered for small-bore centrifugal compressors and turbines with tight internal clearances.

Rated for continuous operation from -52°C to +177°C (-62°F to +351°F), the Bently Nevada 330907-05-30-10-12 withstands harsh thermal environments found in process gas compression and refrigeration systems without performance degradation.

This model includes the FluidLoc cable option, providing superior resistance to oil and liquid ingress at the connector interface, essential for turbine oil environments where standard silicone tape is not recommended.

Description
The Bently Nevada 330907-05-30-10-12 3300 NSv Reverse Mount Probe is specifically engineered for applications where standard 5 mm and 8 mm proximity probes cannot be installed due to counterbore, side-view, or rear-view restrictions. Its reverse mount configuration with M10X1 threads allows mounting in areas with extremely limited access, making it the ideal solution for small shaft diameter machines under 51 mm (2 inches).

Featuring increased chemical resistance compared to the previous 3300 RAM probe, the Bently Nevada 330907-05-30-10-12 is suitable for demanding process compressor applications where exposure to harsh media is common. The probe tip utilizes PPS material with a Viton O-ring seal, and the FluidLoc cable option (included in this configuration) provides enhanced protection against fluid ingress into the connector.

The Bently Nevada 330907-05-30-10-12 incorporates patented TiLoc molding for a robust bond between the probe tip and body, along with the CableLoc design providing 220 N (50 lb) of pull strength. The gold-plated brass ClickLoc connector locks securely to prevent loosening from vibration, and the FEP-insulated coaxial cable maintains signal integrity across a total probe length of 1.0 meter.

Technical notes
The Bently Nevada 330907-05-30-10-12 3300 NSv Reverse Mount Probe must be used with a 3300 XL NSv Proximitor Sensor and a 3300 NSv extension cable; total system length is determined by the sum of probe and extension cable lengths. Calibration is factory-set for AISI 4140 steel targets; recalibration is required for other target materials to maintain specified system accuracy.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What type of machines is this reverse mount probe used on?
It is primarily used on fluid-film bearing machines with small shafts or reduced side-view access, including centrifugal air compressors, refrigeration compressors, process gas compressors, and small turbines where standard probes cannot fit.
Is the FluidLoc cable necessary for all installations?
No. The FluidLoc cable (option 12, as in this model) is specifically recommended when the probe-to-extension cable connection will be exposed to turbine oil or other liquids. For dry environments, standard cable with connector protectors or silicone tape may be sufficient.
Does the Bently Nevada 330907-05-30-10-12 require pressure testing before installation?
No. The Bently Nevada 330907-05-30-10-12 is not pressure tested prior to shipment. If your application requires verification of the pressure seal (Viton O-ring), you must contact Bentley Nevada's custom design department to request this service.
Is the Bently Nevada 330907-05-30-10-12 compatible with 3000-series or 7000-series systems?
No. Upgrading from 3000-series or 7000-series transducer systems requires replacing the probe, extension cable, and Proximitor Sensor with NSv components. The Bently Nevada 330907-05-30-10-12 is designed for 3300 RAM and 3300 XL NSv systems.
