Product Overview
The 330880-16-00-075-00-02 belongs to the high-reliability PROXPAC XL Series by Bently Nevada. This self-contained proximity transducer system integrates an 8mm eddy current probe, extension cable, and Proximitor sensor inside a weather-proof housing. It measures shaft vibration and axial position without direct physical contact. The glass-reinforced Polyphenylene Sulfide (PPS) housing provides rugged IP66 protection, making it suited for outdoor machinery installations lacking auxiliary enclosures.

Target Applications & Machinery Diagnostics
The 330880-16-00-075-00-02 assembly serves heavy industrial machinery where external transmitter boxes are impractical. Typical deployments include induced draft fans, boiler feed pumps, cooling tower gearboxes, and small steam turbines. Vibration analysts use its dynamic raw signal to calculate orbit plots, gap voltages, phase angles, and peak-to-peak displacement for early detection of unbalance, oil whirl, and shaft rub.
Global PLC Spare HUB's Insight
In our field retrofit work on induced draft fans, external junction boxes frequently suffer water intrusion or mechanical damage. Deploying the PROXPAC XL Series eliminated the need for separate Proximitor housings. The 330880-16-00-075-00-02 integrated housing shielded the delicate ClickLoc connector from high vibration. Its conductive PPS shell effectively dumped electrostatic buildup in harsh outdoor environments.
Model Comparison & Technical Recommendations
Review technical variations within the PROXPAC XL Series prior to procurement:
- Short Penetration Baseline: 330880-16-00-075-00-02 provides a 75 mm probe penetration depth with standard 3/4-14 NPT threads and unapproved probe options.
- Extended Standoff Variant: 330880-28-15-285-03-02 offers an extended 285 mm penetration sleeve, a 1.5-inch standoff adapter, multi-approval hazardous certifications, and flexible conduit fittings.
Engineering Selection Tip: Verify physical insertion depth from casing outer wall to shaft surface. Select option -075 when machine wall thickness is thin. If thick insulation covers the machine body, choose model variants with standoff adapters like the 330880-28-15-285-03-02 to keep field wiring terminations accessible outside thermal barriers.

Frequently Asked Questions (FAQ)
Q: What supply voltage range is required to ensure full 80 mil linear measurement range?
A: Power the unit with -23 Vdc to -26 Vdc. Operating more positive than -23.5 Vdc truncates top-end linear range output.
Q: How does the integrated housing change field wiring installation compared to standalone Proximitors?
A: Run three-conductor shielded triaxial cable directly into the housing terminal block, bypassing separate junction boxes.
Q: What failure mode occurs if probe tip exposure falls below -34°C (-29°F)?
A: Sub-zero temperatures below this threshold compromise internal elastomeric pressure seals, causing moisture penetration.
Q: Can option -16 probes operate safely in hazardous gas environments requiring ATEX or IECEx?
A: No, option -16 designates standard unapproved probes. Choose agency-certified probe options if installing in hazardous zones.
Q: What gap setting voltage should engineers target during initial mechanical mounting?
A: Set mechanical position to 1.27 mm (50 mils), which corresponds to approximately -10 Vdc bias reading at center gap.
