Product Introduction
When vibration monitoring systems demand precision and durability, the Bently Nevada 330171-01-10-10-02-00 delivers reliable performance. This 3300 5mm Probe features a 1/4-28 UNF thread configuration without armor, designed for permanent installation in rotating machinery. As part of the trusted 3300 series, this probe provides accurate proximity measurements essential for predictive maintenance and asset protection.
Technical Specifications Breakdown
The Bently Nevada 330171-01-10-10-02-00 incorporates several key specifications that define its operational capabilities:
-
Probe Tip Material: Polyphenylene sulfide (PPS) offers excellent resistance to chemicals and high temperatures.
-
Probe Case Material: AISI 304 stainless steel (SST) ensures corrosion resistance and mechanical strength.
-
Electrical Power: Requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption, with operation above -23.5 Vdc reducing linear range.
-
Output Resistance: 50 Ω for reliable signal transmission.
-
Probe DC Resistance: For 1.0m probe length, resistance from center to outer conductor is 7.59 ± 0.50 Ω.
-
Cable Bend Radius: Minimum 25.4 mm (1.0 in) to prevent cable damage.
-
Probe Temperature Range: -35°C to +177°C (-31°F to +351°F).
-
Weight: 0.323 kg.
Industry Applications
The Bently Nevada 330171-01-10-10-02-00 excels in turbomachinery monitoring, including steam turbines, compressors, and pumps. Its 5mm probe tip and 1/4-28 thread make it ideal for close-coupled installations where space is limited. The probe's 1.0m total length (3.3 feet) with miniature coaxial ClickLoc connector simplifies wiring in control panels. This probe replaces older 3300 series models, offering improved sensitivity (<2 mV change per volt input) and enhanced temperature tolerance.
Maintenance & Reliability
To maximize service life, inspect the probe cable for kinks or abrasion regularly. The gold-plated connectors resist corrosion, but ensure torque during installation: 5.1 N·m (45 in·lb) recommended, maximum 7.3 N·m (65 in·lb). Avoid exposing the probe below -34°C (-30°F) as it may cause pressure seal failure. The 222 N (50 lbf) tensile strength at both probe case-to-lead and lead-to-extension cable connections ensures ruggedness in harsh environments.
Selection Guide & Purchasing Advice
When ordering a replacement or upgrade, verify the unthreaded length (01 = 0.1 in), overall case length (10 = 1.0 in), total length (10 = 1.0 metre), connector option (02 = miniature coaxial ClickLoc), and agency approval option (00). For drilling and tapping a 1/4-28 mounting hole, use a #3 or larger tap drill. PLC Source PRO stocks this exact Bently Nevada 330171-01-10-10-02-00 with full traceability and prompt shipping. Confirm your system's compatibility with the probe's -17.5 Vdc to -26 Vdc power requirement and 50 Ω output resistance.
Troubleshooting & Common Issues
If readings drift, check probe tip contamination—PPS material resists many chemicals but should be cleaned with approved solvents. Verify thread engagement does not exceed 0.375 in to avoid mechanical binding. For magnetic field interference up to 300 Gauss (60 Hz), the probe output remains low (~0.0004 mil pp/gauss at 10 mil gap). If signal noise appears, inspect cable integrity and connector torque (0.565 N·m maximum).
