Product Brief: Bently Nevada 330180-X1-05 145004-137 (3300 XL Proximitor with Right-Angle BNC Connector)
The 330180-X1-05 145004-137 is a Proximitor Sensor (driver/conditioner) for the Bently Nevada 3300 XL 8mm Proximity Probe System. This version features a right-angle (90°) BNC connector (suffix X1) for probe/extension cable attachment, which simplifies installation in tight junction boxes or panels where straight BNC connectors are difficult to route. The 145004-137 is an internal manufacturing or assembly drawing number for this specific configuration.
The Proximitor provides oscillator excitation to the 3300 XL 8mm probe, demodulates the eddy current signal, and outputs a linear DC voltage (‑0.8 VDC to ‑22 VDC) proportional to probe-to-target gap. It is designed for panel or DIN rail mounting in industrial environments and interfaces directly with 3500 series, 1900 series, or third-party monitors/PLCs.

Application Scenarios (use cases)
| Application Area | Description |
|---|---|
| Steam Turbine Junction Box (Tight Space) | Right-angle BNC allows mounting near junction box wall where straight BNC would hit the cover or adjacent components. |
| Gas Turbine Compressor Panel | Retrofit installation in existing panels with limited depth – right-angle connector reduces clearance needed. |
| Offshore Platform Machinery Rack | Sealed IP67 enclosure + right-angle BNC prevents cable strain and moisture ingress in tight marine cabinets. |
| Centrifugal Compressor Junction Box | Mounted on inside of box door; right-angle connector allows cable routing parallel to mounting surface. |
| Test Stand / Temporary Installation | Right-angle connector reduces risk of accidental cable pull-out in crowded test lab setups. |
| Retrofit of 7200 Series Proximitors | Replaces older, larger Proximitors with modern 3300 XL unit – right-angle BNC simplifies re-cabling. |
| Hydro Turbine Pit Panel | Mounted in damp, low-clearance enclosure; right-angle connector keeps cable tidy and protected. |
| Bearing Housing Local Monitor Box | Compact monitor box with 3300 XL Proximitor for local indication or relay output – saves space. |
Notes
330180-X1-05 is the Proximitor only – does NOT include probe, extension cable, or monitor. Order separately:
Probe: e.g., 330171-00-08-10-02-00 (straight) or 330101-00-60-10-02-00 (right-angle)
Extension cable (if needed): 330190-X0-00 (variable length)
X1 connector = Right-angle BNC female. Standard straight BNC is 330180-90-05.
Right-angle BNC reduces required clearance behind the Proximitor to approximately 25 mm (1 inch) versus 50 mm (2 inches) for straight BNC.
145004-137 is an internal Bently Nevada assembly drawing number – not required for ordering; use 330180-X1-05 as the primary ordering number.
DIN rail mounting clip available separately (3300 XL DIN rail adapter kit).
Maximum total cable length from probe tip to Proximitor = 305 m (1000 ft) including probe integral cable and any extension cables.
Not intrinsically safe by itself. For hazardous area installations, use 3300 XL IS Proximitor (different part number) or install external IS barriers between probe and Proximitor.
Output voltage polarity is negative (more negative as gap increases). Most Bently monitors accept this directly. For PLCs needing positive voltage, a level shifter (e.g., 135489-01) is required.
