330172-05-63-05-02-CN Bently Nevada 5mm Probe | 0.5m Armored

Product Overview: Bently Nevada 330172-05-63-05-02-CN

The Bently Nevada 330172-05-63-05-02-CN is a 5mm proximity probe from the 3300 series, engineered for precise displacement and vibration measurement in industrial machinery. It features a 1/4-28 UNF thread and an armored case for mechanical protection. This specific configuration includes a 0.5-meter total length and a miniature coaxial ClickLoc connector. The probe tip is made from polyphenylene sulfide (PPS), while the case uses AISI 304 stainless steel. With a net weight of 0.323 kg, it balances robustness with ease of installation. This probe is designed to operate with a -24 Vdc power supply and a 10 kW load, targeting an AISI 4140 steel target at a 1.27 mm gap. The 330172-05-63-05-02-CN is a reliable choice for maintenance engineers seeking exact, engineering-grade precision in condition monitoring systems.

Key Specifications and Performance

The 330172-05-63-05-02-CN operates on a supply voltage of -17.5 Vdc to -26 Vdc, drawing a maximum of 12 mA. For optimal linear range, operation should avoid voltages more positive than -23.5 Vdc. The probe's sensitivity is less than 2 mV change per volt change in input, ensuring stable output. The output resistance is 50 Ω, and the probe DC resistance from center conductor to outer conductor is 7.45 ± 0.50 Ω at 0.5 m. The 5mm probe offers a tensile strength of 222 N (50 lbf) between the case and lead. It withstands temperatures from -35°C to +177°C, though exposure below -34°C may cause premature seal failure. The recommended probe case torque is 5.1 N·m (45 in·lb), with a maximum of 7.3 N·m (65 in·lb). The connector-to-connector torque ranges from 0.565 N·m (0.42 ft·lbf) maximum, and the minimum cable bend radius is 25.4 mm (1.0 in).

Installation and Maintenance Guidance

When mounting the 330172-05-63-05-02-CN, drill and tap a 1/4-28 hole using a #3 or larger tap drill. The maximum thread engagement is 0.375 in, and the unthreaded length is 0.5 in. The overall case length is 6.3 in. For reliable performance, maintain the specified probe gap and use a -24 Vdc supply. Periodically inspect the armored cable for wear and verify the connector torque. The probe tip material, PPS, is resistant to many chemicals, but avoid exposure to temperatures below -34°C. In case of erratic readings, check for proper grounding and cable integrity. Always follow Bently Nevada's safety manual for maintenance.
