Technical Specifications Breakdown
The Bently Nevada 330172-16-42-10-01-00 operates within a proximity transducer system at temperatures between +18°C and +27°C (+64°F to +80°F) with a -24 Vdc power supply, a 10 kW load, and an AISI 4140 steel target gapped at 1.27 mm (50 mils). Here are the critical electrical and mechanical parameters:
| Parameter |

7.59 ± 0.50 Ω |
| Probe Cable |
75 Ω triaxial, FEP insulated |
| Probe Tensile Strength |
222 N (50 lbf) |
| Probe Case Torque |
5.1 N·m recommended, 7.3 N·m max |
| Connector-to-Connector Torque |
0.565 N·m max |
| Minimum Cable Bend Radius |

The probe's DC resistance is specified at 7.59 ± 0.50 Ω for a 1.0-meter length, ensuring signal integrity. The 75 Ω triaxial cable with FEP insulation provides excellent electrical isolation and durability. The gold-plated brass or beryllium copper connectors resist corrosion and maintain reliable contact.
Installation & Setup Guidance
When installing the Bently Nevada 330172-16-42-10-01-00, ensure proper mounting to achieve accurate readings. For a 1/4-28 probe, use a #3 or larger tap drill when creating a mounting hole. Recommended probe case torque is 5.1 N·m (45 in·lb), with a maximum of 7.3 N·m (65 in·lb) to prevent damage. Maintain a minimum cable bend radius of 25.4 mm (1.0 inch) to avoid stress on the cable. The connector-to-connector torque should not exceed 0.565 N·m (0.42 ft·lbf).
For optimal performance, gap the probe at 1.27 mm (50 mils) from the target, and verify the power supply is within -17.5 Vdc to -26 Vdc. Operating at voltages more positive than -23.5 Vdc may reduce the linear range, so plan your system accordingly.
Maintenance & Reliability
Routine inspection of the probe and cable is essential to maintain reliability. Check for physical damage, especially at the probe tip and cable connections. Avoid exposing the probe to temperatures below -34°C (-30°F), as this may cause premature failure of the pressure seal. The probe's temperature range is -35°C to +177°C, making it suitable for most industrial environments.
Regularly verify the probe's DC resistance to ensure it remains within the specified 7.59 ± 0.50 Ω. Any deviation may indicate cable or connector issues. Keeping the probe clean and free of debris will extend its service life and reduce downtime.
Compatibility & Integration
The Bently Nevada 330172-16-42-10-01-00 is part of the 3300 series and is designed to work with Bently Nevada proximity transducer systems. It integrates seamlessly with XL Proximitor sensors and extension cables. The probe's 75 Ω triaxial cable and ClickLoc connector ensure compatibility with standard Bently Nevada components. For system integration, verify that your monitoring equipment supports the 5mm probe form factor and the specified electrical characteristics.
Selection Guide & Purchasing Advice
Before purchasing the Bently Nevada 330172-16-42-10-01-00, confirm your system requirements: total length, thread type, and connector options. This model features a 1/4-28 UNF thread, a 1.0-meter cable, and a miniature coaxial ClickLoc connector. If your application requires different lengths or connectors, consider other configurations in the 3300 series.
