As part of the 3300 series, this probe features a 1\/4-28 UNF thread, unarmored design, and a 5.0-meter (16.4 ft) cable assembly terminated with a miniature coaxial ClickLoc connector and connector protector. Its rugged construction—polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case—ensures long-term reliability in harsh industrial environments.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications Breakdown\u003c\/h2\u003e\u003cp\u003eThe Bently Nevada 330171-00-12-50-01-CN operates on a power supply requiring -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Its output sensitivity is less than 2 mV change per volt change in input voltage, providing stable readings over the supply range. The probe DC resistance measures 8.73 ± 0.70 Ω for the 5-meter length, ensuring consistent signal transmission. The 75 Ω triaxial FEP-insulated cable minimizes signal loss and resists chemical attack. Temperature range spans -35°C to +177°C, preserving accuracy even near hot bearings.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eWhen installing the Bently Nevada 330171-00-12-50-01-CN, drill and tap a mounting hole using a #3 or larger tap drill for the 1\/4-28 thread. Maximum thread engagement is 0.375 inches. Tighten the probe case to 5.1 N·m (45 in·lb) recommended torque, not exceeding 7.3 N·m (65 in·lb). For the connector-to-connector interface, apply a maximum torque of 0.565 N·m (0.42 ft·lbf). The cable bend radius must be at least 25.4 mm (1.0 in) to prevent internal damage. Always verify that the probe is gapped at 1.27 mm (50 mils) under operating conditions for optimal linear range.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRoutine inspection should focus on the cable jacket and connector integrity. Exposing the probe to temperatures below –34°C (–30°F) can cause premature pressure seal failure. The probe is tolerant of 60 Hz magnetic fields up to 300 Gauss; at a 50-mil gap, the XL Proximitor sensor output variation is only 0.0131 mil pp\/gauss. The gold-plated brass or beryllium copper connectors resist corrosion. Adhering to the specified torque limits prevents thread stripping and ensures reliable readings.\u003c\/p\u003e\u003ch2\u003eTroubleshooting \u0026amp; Common Issues\u003c\/h2\u003e\u003cp\u003eIf the Bently Nevada 330171-00-12-50-01-CN produces erratic signals, check the connector engagement and cable bend radius. Over-tightening the probe case beyond 7.3 N·m can distort the tip and induce nonlinearity. If the probe experiences temperatures below -35°C or above +177°C, the internal components may degrade. Verify the power supply delivers between -17.5 Vdc and -26 Vdc; operating above -23.5 Vdc reduces linear range. For magnetic field interference, ensure the probe is properly grounded and the cable is shielded. When replacing an older probe, confirm the thread size (1\/4-28) and cable length match your system requirements.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore ordering the Bently Nevada 330171-00-12-50-01-CN, verify your system’s thread specification and required cable length. This probe is unarmored; if mechanical protection is needed, consider the armored variant. The CN agency approval indicates country-specific certifications—check compatibility with local regulations.
