Features:
- 165 mm probe penetration with no standoff adapter provides exceptional reach for deep-well mounting through thick machine casings.
- Self-contained design with integrated Proximitor sensor eliminates extension cables and separate Proximitor housings.
- PG21 x M20 fitting accommodates metric conduit systems, with two plugs for flexible installation options.
The 330881-28-00-165-07-02 is engineered for installations where the measurement point sits deep inside the machine casing. Its 165 mm probe penetration allows the sensing tip to reach far into thick turbine casings, heavy compressor walls, or multiple insulation layers without requiring standoffs or custom adapters. The no-standoff design means the assembly mounts flush to the machine casing, eliminating additional components that could loosen or misalign over time.
Unlike traditional systems that require a probe, extension cable, and separate Proximitor housing, the 330881-28-00-165-07-02 integrates the Proximitor sensor directly into the housing cover. Field wiring connects straight from monitors to the assembly, reducing component count, eliminating the extension cable, and cutting potential failure points by two connectors. For system integrators, this means smaller control cabinets and faster commissioning.
The 330881-28-00-165-07-02 includes a PG21 x M20 fitting, providing direct compatibility with metric conduit systems commonly used in European and international installations. The fitting adapts the assembly for metric cable entry while maintaining the hazardous area integrity required for classified locations. Two additional plugs allow unused ports to be sealed, preventing moisture ingress and maintaining environmental protection.
The 330881-28-00-165-07-02 Bently Nevada PROXPAC XL Proximity Transducer may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Narrow observation hole monitoring: When the machine housing counterbore is very small (e.g., diameter less than 9.5 mm), standard 8 mm probes can cause sidewall interference, while the NSV provides a clean signal.
- Small high-speed machinery: Widely used in small centrifugal compressors, turbine expanders, high-speed gearboxes, and aircraft engine test benches.
- External adjustment requirements: Due to its "reverse mounting" design, it is typically installed inside a probe housing, allowing engineers to adjust the clearance between the probe and the shaft externally while the machine is running.
- High Spatial Resolution: NSV technology optimizes the magnetic field shape, requiring less surface area of the target (axis) and providing higher measurement accuracy on small diameter axes (less than 3 inches).
- Linear Range: Offers a linear measurement range of approximately 1.5 mm (60 mils). While slightly shorter than the standard 8 mm probe, it offers superior linearity and repeatability in confined spaces.
- Thermal Stability: Maintains extremely low temperature drift over a range of -35°C to +177°C, ensuring data consistency between cold start-up and warm-up operation.
- Probe Protection Box Integration: Installed in the 32000 series metric protection box. Protects the probe from external physical damage in harsh environments such as petrochemical plants or power plants, while enabling maintenance without shutting down the system.
- Scenario A: Monitoring the vibration of the journal bearings in small turbines.
- Keyphasor Acquisition: Installed in narrow housing openings, it captures keyway signals on
